+README on the ADC/Touchscreen Controller
+========================================
+
+The LH79524 and LH7A404 include a built-in Analog to Digital
+controller (ADC) that is used to process input from a touchscreen.
+The driver only implements a four-wire touch panel protocol.
+
+The touchscreen driver is maintenance free except for the pen-down or
+touch threshold. Some resistive displays and board combinations may
+require tuning of this threshold. The driver exposes some of it's
+internal state in the sys filesystem. If the kernel is configured
+with it, CONFIG_SYSFS, and sysfs is mounted at /sys, there will be a
+directory
+
+ /sys/devices/platform/adc-lh7.0
+
+containing these files.
+
+ -r--r--r-- 1 root root 4096 Jan 1 00:00 samples
+ -rw-r--r-- 1 root root 4096 Jan 1 00:00 threshold
+ -r--r--r-- 1 root root 4096 Jan 1 00:00 threshold_range
+
+The threshold is the current touch threshold. It defaults to 750 on
+most targets.
+
+ # cat threshold
+ 750
+
+The threshold_range contains the range of valid values for the
+threshold. Values outside of this range will be silently ignored.
+
+ # cat threshold_range
+ 0 1023
+
+To change the threshold, write a value to the threshold file.
+
+ # echo 500 > threshold
+ # cat threshold
+ 500
+
+The samples file contains the most recently sampled values from the
+ADC. There are 12. Below are typical of the last sampled values when
+the pen has been released. The first two and last two samples are for
+detecting whether or not the pen is down. The third through sixth are
+X coordinate samples. The seventh through tenth are Y coordinate
+samples.
+
+ # cat samples
+ 1023 1023 0 0 0 0 530 529 530 529 1023 1023
+
+To determine a reasonable threshold, press on the touch panel with an
+appropriate stylus and read the values from samples.
+
+ # cat samples
+ 1023 676 92 103 101 102 855 919 922 922 1023 679
+
+The first and eleventh samples are discarded. Thus, the important
+values are the second and twelfth which are used to determine if the
+pen is down. When both are below the threshold, the driver registers
+that the pen is down. When either is above the threshold, it
+registers then pen is up.

+README on the LCD Panels
+========================
+
+Configuration options for several LCD panels, available from Logic PD,
+are included in the kernel source. This README will help you
+understand the configuration data and give you some guidance for
+adding support for other panels if you wish.
+
+
+lcd-panels.h
+------------
+
+There is no way, at present, to detect which panel is attached to the
+system at runtime. Thus the kernel configuration is static. The file
+arch/arm/mach-ld7a40x/lcd-panels.h (or similar) defines all of the
+panel specific parameters.
+
+It should be possible for this data to be shared among several device
+families. The current layout may be insufficiently general, but it is
+amenable to improvement.
+
+
+PIXEL_CLOCK
+-----------
+
+The panel data sheets will give a range of acceptable pixel clocks.
+The fundamental LCDCLK input frequency is divided down by a PCD
+constant in field '.tim2'. It may happen that it is impossible to set
+the pixel clock within this range. A clock which is too slow will
+tend to flicker. For the highest quality image, set the clock as high
+as possible.
+
+
+MARGINS
+-------
+
+These values may be difficult to glean from the panel data sheet. In
+the case of the Sharp panels, the upper margin is explicitly called
+out as a specific number of lines from the top of the frame. The
+other values may not matter as much as the panels tend to
+automatically center the image.
+
+
+Sync Sense
+----------
+
+The sense of the hsync and vsync pulses may be called out in the data
+sheet. On one panel, the sense of these pulses determine the height
+of the visible region on the panel. Most of the Sharp panels use
+negative sense sync pulses set by the TIM2_IHS and TIM2_IVS bits in
+'.tim2'.
+
+
+Pel Layout
+----------
+
+The Sharp color TFT panels are all configured for 16 bit direct color
+modes. The amba-lcd driver sets the pel mode to 565 for 5 bits of
+each red and blue and 6 bits of green.

+
+READ MEMORY BARRIERS VS LOAD SPECULATION
+----------------------------------------
+
+Many CPUs speculate with loads: that is they see that they will need to load an
+item from memory, and they find a time where they're not using the bus for any
+other loads, and so do the load in advance - even though they haven't actually
+got to that point in the instruction execution flow yet. This permits the
+actual load instruction to potentially complete immediately because the CPU
+already has the value to hand.
+
+It may turn out that the CPU didn't actually need the value - perhaps because a
+branch circumvented the load - in which case it can discard the value or just
+cache it for later use.

+3.4 Configuring Bonding Manually via Sysfs
+------------------------------------------
-5. Querying Bonding Configuration
+ Starting with version 3.0, Channel Bonding may be configured
+via the sysfs interface. This interface allows dynamic configuration
+of all bonds in the system without unloading the module. It also
+allows for adding and removing bonds at runtime. Ifenslave is no
+longer required, though it is still supported.
+
+ Use of the sysfs interface allows you to use multiple bonds
+with different configurations without having to reload the module.
+It also allows you to use multiple, differently configured bonds when
+bonding is compiled into the kernel.
+
+ You must have the sysfs filesystem mounted to configure
+bonding this way. The examples in this document assume that you
+are using the standard mount point for sysfs, e.g. /sys. If your
+sysfs filesystem is mounted elsewhere, you will need to adjust the
+example paths accordingly.
+
+Creating and Destroying Bonds
+-----------------------------
+To add a new bond foo:
+# echo +foo > /sys/class/net/bonding_masters
+
+To remove an existing bond bar:
+# echo -bar > /sys/class/net/bonding_masters
+
+To show all existing bonds:
+# cat /sys/class/net/bonding_masters
+
+NOTE: due to 4K size limitation of sysfs files, this list may be
+truncated if you have more than a few hundred bonds. This is unlikely
+to occur under normal operating conditions.
+
+Adding and Removing Slaves
+--------------------------
+ Interfaces may be enslaved to a bond using the file
+/sys/class/net/<bond>/bonding/slaves. The semantics for this file
+are the same as for the bonding_masters file.
+
+To enslave interface eth0 to bond bond0:
+# ifconfig bond0 up
+# echo +eth0 > /sys/class/net/bond0/bonding/slaves
+
+To free slave eth0 from bond bond0:
+# echo -eth0 > /sys/class/net/bond0/bonding/slaves
+
+ NOTE: The bond must be up before slaves can be added. All
+slaves are freed when the interface is brought down.
+
+ When an interface is enslaved to a bond, symlinks between the
+two are created in the sysfs filesystem. In this case, you would get
+/sys/class/net/bond0/slave_eth0 pointing to /sys/class/net/eth0, and
+/sys/class/net/eth0/master pointing to /sys/class/net/bond0.
+
+ This means that you can tell quickly whether or not an
+interface is enslaved by looking for the master symlink. Thus:
+# echo -eth0 > /sys/class/net/eth0/master/bonding/slaves
+will free eth0 from whatever bond it is enslaved to, regardless of
+the name of the bond interface.
+
+Changing a Bond's Configuration
+-------------------------------
+ Each bond may be configured individually by manipulating the
+files located in /sys/class/net/<bond name>/bonding
+
+ The names of these files correspond directly with the command-
+line parameters described elsewhere in in this file, and, with the
+exception of arp_ip_target, they accept the same values. To see the
+current setting, simply cat the appropriate file.
+
+ A few examples will be given here; for specific usage
+guidelines for each parameter, see the appropriate section in this
+document.
+
+To configure bond0 for balance-alb mode:
+# ifconfig bond0 down
+# echo 6 > /sys/class/net/bond0/bonding/mode
+ - or -
+# echo balance-alb > /sys/class/net/bond0/bonding/mode
+ NOTE: The bond interface must be down before the mode can be
+changed.
+
+To enable MII monitoring on bond0 with a 1 second interval:
+# echo 1000 > /sys/class/net/bond0/bonding/miimon
+ NOTE: If ARP monitoring is enabled, it will disabled when MII
+monitoring is enabled, and vice-versa.
+
+To add ARP targets:
+# echo +192.168.0.100 > /sys/class/net/bond0/bonding/arp_ip_target
+# echo +192.168.0.101 > /sys/class/net/bond0/bonding/arp_ip_target
+ NOTE: up to 10 target addresses may be specified.
+
+To remove an ARP target:
+# echo -192.168.0.100 > /sys/class/net/bond0/bonding/arp_ip_target
+
+Example Configuration
+---------------------
+ We begin with the same example that is shown in section 3.3,
+executed with sysfs, and without using ifenslave.
+
+ To make a simple bond of two e100 devices (presumed to be eth0
+and eth1), and have it persist across reboots, edit the appropriate
+file (/etc/init.d/boot.local or /etc/rc.d/rc.local), and add the
+following:
+
+modprobe bonding
+modprobe e100
+echo balance-alb > /sys/class/net/bond0/bonding/mode
+ifconfig bond0 192.168.1.1 netmask 255.255.255.0 up
+echo 100 > /sys/class/net/bond0/bonding/miimon
+echo +eth0 > /sys/class/net/bond0/bonding/slaves
+echo +eth1 > /sys/class/net/bond0/bonding/slaves
+
+ To add a second bond, with two e1000 interfaces in
+active-backup mode, using ARP monitoring, add the following lines to
+your init script:
+
+modprobe e1000
+echo +bond1 > /sys/class/net/bonding_masters
+echo active-backup > /sys/class/net/bond1/bonding/mode
+ifconfig bond1 192.168.2.1 netmask 255.255.255.0 up

+
+1. Introduction
+
+Linux distinguishes between administrative and operational state of an
+interface. Admininstrative state is the result of "ip link set dev
+<dev> up or down" and reflects whether the administrator wants to use
+the device for traffic.
+
+However, an interface is not usable just because the admin enabled it
+- ethernet requires to be plugged into the switch and, depending on
+a site's networking policy and configuration, an 802.1X authentication
+to be performed before user data can be transferred. Operational state
+shows the ability of an interface to transmit this user data.
+
+Thanks to 802.1X, userspace must be granted the possibility to
+influence operational state. To accommodate this, operational state is
+split into two parts: Two flags that can be set by the driver only, and
+a RFC2863 compatible state that is derived from these flags, a policy,
+and changeable from userspace under certain rules.
+
+
+2. Querying from userspace
+
+Both admin and operational state can be queried via the netlink
+operation RTM_GETLINK. It is also possible to subscribe to RTMGRP_LINK
+to be notified of updates. This is important for setting from userspace.
+
+These values contain interface state:
+
+ifinfomsg::if_flags & IFF_UP:
+ Interface is admin up
+ifinfomsg::if_flags & IFF_RUNNING:
+ Interface is in RFC2863 operational state UP or UNKNOWN. This is for
+ backward compatibility, routing daemons, dhcp clients can use this
+ flag to determine whether they should use the interface.
+ifinfomsg::if_flags & IFF_LOWER_UP:
+ Driver has signaled netif_carrier_on()
+ifinfomsg::if_flags & IFF_DORMANT:
+ Driver has signaled netif_dormant_on()
+
+These interface flags can also be queried without netlink using the
+SIOCGIFFLAGS ioctl.
+
+TLV IFLA_OPERSTATE
+
+contains RFC2863 state of the interface in numeric representation:
+
+IF_OPER_UNKNOWN (0):
+ Interface is in unknown state, neither driver nor userspace has set
+ operational state. Interface must be considered for user data as
+ setting operational state has not been implemented in every driver.
+IF_OPER_NOTPRESENT (1):
+ Unused in current kernel (notpresent interfaces normally disappear),
+ just a numerical placeholder.
+IF_OPER_DOWN (2):
+ Interface is unable to transfer data on L1, f.e. ethernet is not
+ plugged or interface is ADMIN down.
+IF_OPER_LOWERLAYERDOWN (3):
+ Interfaces stacked on an interface that is IF_OPER_DOWN show this
+ state (f.e. VLAN).
+IF_OPER_TESTING (4):
+ Unused in current kernel.
+IF_OPER_DORMANT (5):
+ Interface is L1 up, but waiting for an external event, f.e. for a
+ protocol to establish. (802.1X)
+IF_OPER_UP (6):
+ Interface is operational up and can be used.
+
+This TLV can also be queried via sysfs.
+
+TLV IFLA_LINKMODE
+
+contains link policy. This is needed for userspace interaction
+described below.
+
+This TLV can also be queried via sysfs.
+
+
+3. Kernel driver API
+
+Kernel drivers have access to two flags that map to IFF_LOWER_UP and
+IFF_DORMANT. These flags can be set from everywhere, even from
+interrupts. It is guaranteed that only the driver has write access,
+however, if different layers of the driver manipulate the same flag,
+the driver has to provide the synchronisation needed.
+
+__LINK_STATE_NOCARRIER, maps to !IFF_LOWER_UP:
+
+The driver uses netif_carrier_on() to clear and netif_carrier_off() to
+set this flag. On netif_carrier_off(), the scheduler stops sending
+packets. The name 'carrier' and the inversion are historical, think of
+it as lower layer.
+
+netif_carrier_ok() can be used to query that bit.
+
+__LINK_STATE_DORMANT, maps to IFF_DORMANT:
+
+Set by the driver to express that the device cannot yet be used
+because some driver controlled protocol establishment has to
+complete. Corresponding functions are netif_dormant_on() to set the
+flag, netif_dormant_off() to clear it and netif_dormant() to query.
+
+On device allocation, networking core sets the flags equivalent to
+netif_carrier_ok() and !netif_dormant().
+
+
+Whenever the driver CHANGES one of these flags, a workqueue event is
+scheduled to translate the flag combination to IFLA_OPERSTATE as
+follows:
+
+!netif_carrier_ok():
+ IF_OPER_LOWERLAYERDOWN if the interface is stacked, IF_OPER_DOWN
+ otherwise. Kernel can recognise stacked interfaces because their
+ ifindex != iflink.
+
+netif_carrier_ok() && netif_dormant():
+ IF_OPER_DORMANT
+
+netif_carrier_ok() && !netif_dormant():
+ IF_OPER_UP if userspace interaction is disabled. Otherwise
+ IF_OPER_DORMANT with the possibility for userspace to initiate the
+ IF_OPER_UP transition afterwards.
+
+
+4. Setting from userspace
+
+Applications have to use the netlink interface to influence the
+RFC2863 operational state of an interface. Setting IFLA_LINKMODE to 1
+via RTM_SETLINK instructs the kernel that an interface should go to
+IF_OPER_DORMANT instead of IF_OPER_UP when the combination
+netif_carrier_ok() && !netif_dormant() is set by the
+driver. Afterwards, the userspace application can set IFLA_OPERSTATE
+to IF_OPER_DORMANT or IF_OPER_UP as long as the driver does not set
+netif_carrier_off() or netif_dormant_on(). Changes made by userspace
+are multicasted on the netlink group RTMGRP_LINK.
+
+So basically a 802.1X supplicant interacts with the kernel like this:
+
+-subscribe to RTMGRP_LINK
+-set IFLA_LINKMODE to 1 via RTM_SETLINK
+-query RTM_GETLINK once to get initial state
+-if initial flags are not (IFF_LOWER_UP && !IFF_DORMANT), wait until
+ netlink multicast signals this state
+-do 802.1X, eventually abort if flags go down again
+-send RTM_SETLINK to set operstate to IF_OPER_UP if authentication
+ succeeds, IF_OPER_DORMANT otherwise
+-see how operstate and IFF_RUNNING is echoed via netlink multicast
+-set interface back to IF_OPER_DORMANT if 802.1X reauthentication
+ fails
+-restart if kernel changes IFF_LOWER_UP or IFF_DORMANT flag
+
+if supplicant goes down, bring back IFLA_LINKMODE to 0 and
+IFLA_OPERSTATE to a sane value.
+
+A routing daemon or dhcp client just needs to care for IFF_RUNNING or
+waiting for operstate to go IF_OPER_UP/IF_OPER_UNKNOWN before
+considering the interface / querying a DHCP address.
+
+

+PXA2xx SPI on SSP driver HOWTO
+===================================================
+This a mini howto on the pxa2xx_spi driver. The driver turns a PXA2xx
+synchronous serial port into a SPI master controller
+(see Documentation/spi/spi_summary). The driver has the following features
+
+- Support for any PXA2xx SSP
+- SSP PIO and SSP DMA data transfers.
+- External and Internal (SSPFRM) chip selects.
+- Per slave device (chip) configuration.
+- Full suspend, freeze, resume support.
+
+The driver is built around a "spi_message" fifo serviced by workqueue and a
+tasklet. The workqueue, "pump_messages", drives message fifo and the tasklet
+(pump_transfer) is responsible for queuing SPI transactions and setting up and
+launching the dma/interrupt driven transfers.

+-----------------------------------
+Typically a SPI master is defined in the arch/.../mach-*/board-*.c as a
+"platform device". The master configuration is passed to the driver via a table
+found in include/asm-arm/arch-pxa/pxa2xx_spi.h:
+
+struct pxa2xx_spi_master {
+ enum pxa_ssp_type ssp_type;
+ u32 clock_enable;
+ u16 num_chipselect;
+ u8 enable_dma;
+};
+
+The "pxa2xx_spi_master.ssp_type" field must have a value between 1 and 3 and
+informs the driver which features a particular SSP supports.
+
+The "pxa2xx_spi_master.clock_enable" field is used to enable/disable the
+corresponding SSP peripheral block in the "Clock Enable Register (CKEN"). See
+the "PXA2xx Developer Manual" section "Clocks and Power Management".
+
+The "pxa2xx_spi_master.num_chipselect" field is used to determine the number of
+slave device (chips) attached to this SPI master.
+
+The "pxa2xx_spi_master.enable_dma" field informs the driver that SSP DMA should
+be used. This caused the driver to acquire two DMA channels: rx_channel and
+tx_channel. The rx_channel has a higher DMA service priority the tx_channel.
+See the "PXA2xx Developer Manual" section "DMA Controller".
+
+NSSP MASTER SAMPLE
+------------------
+Below is a sample configuration using the PXA255 NSSP.
+
+static struct resource pxa_spi_nssp_resources[] = {
+ [0] = {
+ .start = __PREG(SSCR0_P(2)), /* Start address of NSSP */
+ .end = __PREG(SSCR0_P(2)) + 0x2c, /* Range of registers */
+ .flags = IORESOURCE_MEM,
+ },
+ [1] = {
+ .start = IRQ_NSSP, /* NSSP IRQ */
+ .end = IRQ_NSSP,
+ .flags = IORESOURCE_IRQ,
+ },
+};
+
+static struct pxa2xx_spi_master pxa_nssp_master_info = {
+ .ssp_type = PXA25x_NSSP, /* Type of SSP */
+ .clock_enable = CKEN9_NSSP, /* NSSP Peripheral clock */
+ .num_chipselect = 1, /* Matches the number of chips attached to NSSP */
+ .enable_dma = 1, /* Enables NSSP DMA */
+};
+
+static struct platform_device pxa_spi_nssp = {
+ .name = "pxa2xx-spi", /* MUST BE THIS VALUE, so device match driver */
+ .id = 2, /* Bus number, MUST MATCH SSP number 1..n */
+ .resource = pxa_spi_nssp_resources,
+ .num_resources = ARRAY_SIZE(pxa_spi_nssp_resources),
+ .dev = {
+ .platform_data = &pxa_nssp_master_info, /* Passed to driver */
+ },
+};
+
+static struct platform_device *devices[] __initdata = {
+ &pxa_spi_nssp,
+};
+
+static void __init board_init(void)
+{
+ (void)platform_add_device(devices, ARRAY_SIZE(devices));
+}
+
+Declaring Slave Devices
+-----------------------
+Typically each SPI slave (chip) is defined in the arch/.../mach-*/board-*.c
+using the "spi_board_info" structure found in "linux/spi/spi.h". See
+"Documentation/spi/spi_summary" for additional information.
+
+Each slave device attached to the PXA must provide slave specific configuration
+information via the structure "pxa2xx_spi_chip" found in
+"include/asm-arm/arch-pxa/pxa2xx_spi.h". The pxa2xx_spi master controller driver
+will uses the configuration whenever the driver communicates with the slave
+device.
+
+struct pxa2xx_spi_chip {
+ u8 tx_threshold;
+ u8 rx_threshold;
+ u8 dma_burst_size;
+ u32 timeout_microsecs;
+ u8 enable_loopback;
+ void (*cs_control)(u32 command);
+};
+
+The "pxa2xx_spi_chip.tx_threshold" and "pxa2xx_spi_chip.rx_threshold" fields are
+used to configure the SSP hardware fifo. These fields are critical to the
+performance of pxa2xx_spi driver and misconfiguration will result in rx
+fifo overruns (especially in PIO mode transfers). Good default values are
+
+ .tx_threshold = 12,
+ .rx_threshold = 4,
+
+The "pxa2xx_spi_chip.dma_burst_size" field is used to configure PXA2xx DMA
+engine and is related the "spi_device.bits_per_word" field. Read and understand
+the PXA2xx "Developer Manual" sections on the DMA controller and SSP Controllers
+to determine the correct value. An SSP configured for byte-wide transfers would
+use a value of 8.
+
+The "pxa2xx_spi_chip.timeout_microsecs" fields is used to efficiently handle
+trailing bytes in the SSP receiver fifo. The correct value for this field is
+dependent on the SPI bus speed ("spi_board_info.max_speed_hz") and the specific
+slave device. Please note the the PXA2xx SSP 1 does not support trailing byte
+timeouts and must busy-wait any trailing bytes.
+
+The "pxa2xx_spi_chip.enable_loopback" field is used to place the SSP porting
+into internal loopback mode. In this mode the SSP controller internally
+connects the SSPTX pin the the SSPRX pin. This is useful for initial setup
+testing.
+
+The "pxa2xx_spi_chip.cs_control" field is used to point to a board specific
+function for asserting/deasserting a slave device chip select. If the field is
+NULL, the pxa2xx_spi master controller driver assumes that the SSP port is
+configured to use SSPFRM instead.
+
+NSSP SALVE SAMPLE
+-----------------
+The pxa2xx_spi_chip structure is passed to the pxa2xx_spi driver in the
+"spi_board_info.controller_data" field. Below is a sample configuration using
+the PXA255 NSSP.
+
+/* Chip Select control for the CS8415A SPI slave device */
+static void cs8415a_cs_control(u32 command)

+ .timeout_microsecs = 64, /* Wait at least 64usec to handle trailing */
+ .cs_control = cs8405a_cs_control, /* Use external chip select */
+};
+
+static struct spi_board_info streetracer_spi_board_info[] __initdata = {
+ {
+ .modalias = "cs8415a", /* Name of spi_driver for this device */
+ .max_speed_hz = 3686400, /* Run SSP as fast a possbile */
+ .bus_num = 2, /* Framework bus number */
+ .chip_select = 0, /* Framework chip select */
+ .platform_data = NULL; /* No spi_driver specific config */
+ .controller_data = &cs8415a_chip_info, /* Master chip config */
+ .irq = STREETRACER_APCI_IRQ, /* Slave device interrupt */
+ },
+ {
+ .modalias = "cs8405a", /* Name of spi_driver for this device */
+ .max_speed_hz = 3686400, /* Run SSP as fast a possbile */

+ .controller_data = &cs8405a_chip_info, /* Master chip config */

+ },
+};
+
+static void __init streetracer_init(void)
+{
+ spi_register_board_info(streetracer_spi_board_info,
+ ARRAY_SIZE(streetracer_spi_board_info));
+}
+
+
+DMA and PIO I/O Support
+-----------------------
+The pxa2xx_spi driver support both DMA and interrupt driven PIO message
+transfers. The driver defaults to PIO mode and DMA transfers must enabled by
+setting the "enable_dma" flag in the "pxa2xx_spi_master" structure and and
+ensuring that the "pxa2xx_spi_chip.dma_burst_size" field is non-zero. The DMA
+mode support both coherent and stream based DMA mappings.
+
+The following logic is used to determine the type of I/O to be used on
+a per "spi_transfer" basis:
+
+if !enable_dma or dma_burst_size == 0 then
+ always use PIO transfers
+
+if spi_message.is_dma_mapped and rx_dma_buf != 0 and tx_dma_buf != 0 then
+ use coherent DMA mode
+
+if rx_buf and tx_buf are aligned on 8 byte boundary then
+ use streaming DMA mode
+
+otherwise
+ use PIO transfer
+
+THANKS TO

+David Brownell and others for mentoring the development of this driver.

+BUS NUMBERING

+Bus numbering is important, since that's how Linux identifies a given

+manufacturer. For example, hardware controller SPI2 would be bus number 2,
+and spi_board_info for devices connected to it would use that number.
+
+If you don't have such hardware-assigned bus number, and for some reason

+ -----------
+ DESCRIPTION
+ -----------
+
+ Only one panel may be defined at a time.
+
+ The pixel clock is calculated to be no greater than the target.
+
+ Each timing value is accompanied by a specification comment.
+
+ UNITS/MIN/TYP/MAX
+
+ Most of the units will be in clocks.
+
+ USE_RGB555
+
+ Define this macro to configure the AMBA LCD controller to use an
+ RGB555 encoding for the pels instead of the normal RGB565.
+
+ LPD9520, LPD79524, LPD7A400, LPD7A404-10, LPD7A404-11
+
+ These boards are best approximated by 555 for all panels. Some
+ can use an extra low-order bit of blue in bit 16 of the color
+ value, but we don't have a way to communicate this non-linear
+ mapping to the kernel.

+ o *** This driver is cribbed from the 7952x implementation.

+
+ o This driver contains sufficient logic to control either the
+ serial EEPROMs or the audio codec. It is included in the kernel
+ to support the codec. The EEPROMs are really the responsibility
+ of the boot loader and should probably be left alone.
+
+ o The code must be augmented to cope with multiple, simultaneous
+ clients.
+ o The audio codec writes to the codec chip whenever playback
+ starts.
+ o The touchscreen driver writes to the ads chip every time it
+ samples.
+ o The audio codec must write 16 bits, but the touch chip writes
+ are 8 bits long.
+ o We need to be able to keep these configurations separate while

+ * This code implements the DMA subsystem. It provides a HW-neutral interface
+ * for other kernel code to use asynchronous memory copy capabilities,
+ * if present, and allows different HW DMA drivers to register as providing
+ * this capability.
+ *
+ * Due to the fact we are accelerating what is already a relatively fast
+ * operation, the code goes to great lengths to avoid additional overhead,
+ * such as locking.
+ *
+ * LOCKING:
+ *
+ * The subsystem keeps two global lists, dma_device_list and dma_client_list.
+ * Both of these are protected by a mutex, dma_list_mutex.
+ *
+ * Each device has a channels list, which runs unlocked but is never modified
+ * once the device is registered, it's just setup by the driver.
+ *
+ * Each client has a channels list, it's only modified under the client->lock
+ * and in an RCU callback, so it's safe to read under rcu_read_lock().
+ *
+ * Each device has a kref, which is initialized to 1 when the device is
+ * registered. A kref_put is done for each class_device registered. When the
+ * class_device is released, the coresponding kref_put is done in the release
+ * method. Every time one of the device's channels is allocated to a client,
+ * a kref_get occurs. When the channel is freed, the coresponding kref_put
+ * happens. The device's release function does a completion, so
+ * unregister_device does a remove event, class_device_unregister, a kref_put
+ * for the first reference, then waits on the completion for all other
+ * references to finish.
+ *
+ * Each channel has an open-coded implementation of Rusty Russell's "bigref,"
+ * with a kref and a per_cpu local_t. A single reference is set when on an
+ * ADDED event, and removed with a REMOVE event. Net DMA client takes an
+ * extra reference per outstanding transaction. The relase function does a
+ * kref_put on the device. -ChrisL

+ * The ib_uobject locking scheme is as follows:

+ * dropping this lock.
+ *
+ * - Each object also has an rwsem. This rwsem must be held for
+ * reading while an operation that uses the object is performed.
+ * For example, while registering an MR, the associated PD's
+ * uobject.mutex must be held for reading. The rwsem must be held
+ * for writing while initializing or destroying an object.
+ *
+ * - In addition, each object has a "live" flag. If this flag is not
+ * set, then lookups of the object will fail even if it is found in
+ * the idr. This handles a reader that blocks and does not acquire
+ * the rwsem until after the object is destroyed. The destroy
+ * operation will set the live flag to 0 and then drop the rwsem;
+ * this will allow the reader to acquire the rwsem, see that the
+ * live flag is 0, and then drop the rwsem and its reference to
+ * object. The underlying storage will not be freed until the last

- *
- * 04-14-2004 tglx: first working version for 2k page size chips
- *
- * 05-19-2004 tglx: Basic support for Renesas AG-AND chips
- *
- * 09-24-2004 tglx: add support for hardware controllers (e.g. ECC) shared
- * among multiple independend devices. Suggestions and initial patch
- * from Ben Dooks <ben-mtd@fluff.org>
- *
- * 12-05-2004 dmarlin: add workaround for Renesas AG-AND chips "disturb" issue.
- * Basically, any block not rewritten may lose data when surrounding blocks
- * are rewritten many times. JFFS2 ensures this doesn't happen for blocks
- * it uses, but the Bad Block Table(s) may not be rewritten. To ensure they
- * do not lose data, force them to be rewritten when some of the surrounding
- * blocks are erased. Rather than tracking a specific nearby block (which
- * could itself go bad), use a page address 'mask' to select several blocks
- * in the same area, and rewrite the BBT when any of them are erased.
- *
- * 01-03-2005 dmarlin: added support for the device recovery command sequence for Renesas
- * AG-AND chips. If there was a sudden loss of power during an erase operation,
- * a "device recovery" operation must be performed when power is restored
- * to ensure correct operation.
- *
- * 01-20-2005 dmarlin: added support for optional hardware specific callback routine to
- * perform extra error status checks on erase and write failures. This required
- * adding a wrapper function for nand_read_ecc.
- *
- * 08-20-2005 vwool: suspend/resume added
- *
- * Credits:
+ * Credits:
* David Woodhouse for adding multichip support
*
* Aleph One Ltd. and Toby Churchill Ltd. for supporting the
* rework for 2K page size chips

- * TODO:
+ * TODO:
* Enable cached programming for 2k page size chips
* Check, if mtd->ecctype should be set to MTD_ECC_HW
* if we have HW ecc support.
* The AG-AND chips have nice features for speed improvement,
* which are not supported yet. Read / program 4 pages in one go.

-/* Change Log
- * 7.0.33 3-Feb-2006
- * o Added another fix for the pass false carrier bit
- * 7.0.32 24-Jan-2006
- * o Need to rebuild with noew version number for the pass false carrier
- * fix in e1000_hw.c
- * 7.0.30 18-Jan-2006
- * o fixup for tso workaround to disable it for pci-x
- * o fix mem leak on 82542
- * o fixes for 10 Mb/s connections and incorrect stats
- * 7.0.28 01/06/2006
- * o hardware workaround to only set "speed mode" bit for 1G link.
- * 7.0.26 12/23/2005
- * o wake on lan support modified for device ID 10B5
- * o fix dhcp + vlan issue not making it to the iAMT firmware
- * 7.0.24 12/9/2005
- * o New hardware support for the Gigabit NIC embedded in the south bridge
- * o Fixes to the recycling logic (skb->tail) from IBM LTC
- * 6.3.9 12/16/2005
- * o incorporate fix for recycled skbs from IBM LTC
- * 6.3.7 11/18/2005
- * o Honor eeprom setting for enabling/disabling Wake On Lan
- * 6.3.5 11/17/2005
- * o Fix memory leak in rx ring handling for PCI Express adapters
- * 6.3.4 11/8/05
- * o Patch from Jesper Juhl to remove redundant NULL checks for kfree
- * 6.3.2 9/20/05
- * o Render logic that sets/resets DRV_LOAD as inline functions to
- * avoid code replication. If f/w is AMT then set DRV_LOAD only when
- * network interface is open.
- * o Handle DRV_LOAD set/reset in cases where AMT uses VLANs.
- * o Adjust PBA partioning for Jumbo frames using MTU size and not
- * rx_buffer_len
- * 6.3.1 9/19/05
- * o Use adapter->tx_timeout_factor in Tx Hung Detect logic
- * (e1000_clean_tx_irq)
- * o Support for 8086:10B5 device (Quad Port)

- * Theory of operation...
- * -------------------
- * Maybe you had a look in orinoco_plx. Well, this is totally different...
- *
- * The card contains only one PCI region, which contains all the usual
- * hermes registers.
- *
- * The driver will memory map this region in normal memory. Because
- * the hermes registers are mapped in normal memory and not in ISA I/O
- * post space, we can't use the usual inw/outw macros and we need to
- * use readw/writew.
- * This slight difference force us to compile our own version of
- * hermes.c with the register access macro changed. That's a bit
- * hackish but works fine.
- *
- * Note that the PCI region is pretty big (4K). That's much more than
- * the usual set of hermes register (0x0 -> 0x3E). I've got a strong
- * suspicion that the whole memory space of the adapter is in fact in
- * this region. Accessing directly the adapter memory instead of going
- * through the usual register would speed up significantely the
- * operations...
- *
- * Finally, the card looks like this :

- Network controller: PCI device 1260:3873 (Harris Semiconductor) (rev 1).
- IRQ 11.
- Master Capable. Latency=248.

+Version 1.43
+------------
+POSIX locking to servers which support CIFS POSIX Extensions
+(disabled by default controlled by proc/fs/cifs/Experimental).
+Handle conversion of long share names (especially Asian languages)
+to Unicode during mount.

Version 1.42
------------
Fix slow oplock break when mounted to different servers at the same time and
-the tids match and we try to find matching fid on wrong server.
+the tids match and we try to find matching fid on wrong server. Fix read
+looping when signing required by server (2.6.16 kernel only). Fix readdir
+vs. rename race which could cause each to hang. Return . and .. even
+if server does not. Allow searches to skip first three entries and
+begin at any location. Fix oops in find_writeable_file.

Ordering constraints:
Lock wbuf_sem last, after the alloc_sem or and f->sem.
+
+
+ c->xattr_sem
+ ------------
+
+This read/write semaphore protects against concurrent access to the
+xattr related objects which include stuff in superblock and ic->xref.
+In read-only path, write-semaphore is too much exclusion. It's enough
+by read-semaphore. But you must hold write-semaphore when updating,
+creating or deleting any xattr related object.
+
+Once xattr_sem released, there would be no assurance for the existence
+of those objects. Thus, a series of processes is often required to retry,
+when updating such a object is necessary under holding read semaphore.
+For example, do_jffs2_getxattr() holds read-semaphore to scan xref and
+xdatum at first. But it retries this process with holding write-semaphore
+after release read-semaphore, if it's necessary to load name/value pair
+from medium.
+
+Ordering constraints:
+ Lock xattr_sem last, after the alloc_sem.

+ * xattr_datum_hashkey(xprefix, xname, xvalue, xsize)
+ * is used to calcurate xdatum hashkey. The reminder of hashkey into XATTRINDEX_HASHSIZE is
+ * the index of the xattr name/value pair cache (c->xattrindex).
+ * unload_xattr_datum(c, xd)
+ * is used to release xattr name/value pair and detach from c->xattrindex.
+ * reclaim_xattr_datum(c)
+ * is used to reclaim xattr name/value pairs on the xattr name/value pair cache when
+ * memory usage by cache is over c->xdatum_mem_threshold. Currentry, this threshold
+ * is hard coded as 32KiB.
+ * delete_xattr_datum_node(c, xd)
+ * is used to delete a jffs2 node is dominated by xdatum. When EBS(Erase Block Summary) is
+ * enabled, it overwrites the obsolete node by myself.
+ * delete_xattr_datum(c, xd)
+ * is used to delete jffs2_xattr_datum object. It must be called with 0-value of reference
+ * counter. (It means how many jffs2_xattr_ref object refers this xdatum.)
+ * do_verify_xattr_datum(c, xd)
+ * is used to load the xdatum informations without name/value pair from the medium.
+ * It's necessary once, because those informations are not collected during mounting
+ * process when EBS is enabled.
+ * 0 will be returned, if success. An negative return value means recoverable error, and
+ * positive return value means unrecoverable error. Thus, caller must remove this xdatum
+ * and xref when it returned positive value.
+ * do_load_xattr_datum(c, xd)
+ * is used to load name/value pair from the medium.
+ * The meanings of return value is same as do_verify_xattr_datum().
+ * load_xattr_datum(c, xd)
+ * is used to be as a wrapper of do_verify_xattr_datum() and do_load_xattr_datum().
+ * If xd need to call do_verify_xattr_datum() at first, it's called before calling
+ * do_load_xattr_datum(). The meanings of return value is same as do_verify_xattr_datum().
+ * save_xattr_datum(c, xd)
+ * is used to write xdatum to medium. xd->version will be incremented.
+ * create_xattr_datum(c, xprefix, xname, xvalue, xsize)
+ * is used to create new xdatum and write to medium.

- * Changelog:
- * 01-31-2000 DMW Created
- * 09-18-2000 SJH Moved structure out of the Disk-On-Chip drivers
- * so it can be used by other NAND flash device
- * drivers. I also changed the copyright since none
- * of the original contents of this file are specific
- * to DoC devices. David can whack me with a baseball
- * bat later if I did something naughty.
- * 10-11-2000 SJH Added private NAND flash structure for driver
- * 10-24-2000 SJH Added prototype for 'nand_scan' function
- * 10-29-2001 TG changed nand_chip structure to support
- * hardwarespecific function for accessing control lines
- * 02-21-2002 TG added support for different read/write adress and
- * ready/busy line access function
- * 02-26-2002 TG added chip_delay to nand_chip structure to optimize
- * command delay times for different chips
- * 04-28-2002 TG OOB config defines moved from nand.c to avoid duplicate
- * defines in jffs2/wbuf.c
- * 08-07-2002 TG forced bad block location to byte 5 of OOB, even if
- * CONFIG_MTD_NAND_ECC_JFFS2 is not set
- * 08-10-2002 TG extensions to nand_chip structure to support HW-ECC
- *
- * 08-29-2002 tglx nand_chip structure: data_poi for selecting
- * internal / fs-driver buffer
- * support for 6byte/512byte hardware ECC
- * read_ecc, write_ecc extended for different oob-layout
- * oob layout selections: NAND_NONE_OOB, NAND_JFFS2_OOB,
- * NAND_YAFFS_OOB
- * 11-25-2002 tglx Added Manufacturer code FUJITSU, NATIONAL
- * Split manufacturer and device ID structures
- *
- * 02-08-2004 tglx added option field to nand structure for chip anomalities
- * 05-25-2004 tglx added bad block table support, ST-MICRO manufacturer id
- * update of nand_chip structure description
- * 01-17-2005 dmarlin added extended commands for AG-AND device and added option
- * for BBT_AUTO_REFRESH.
- * 01-20-2005 dmarlin added optional pointer to hardware specific callback for
- * extra error status checks.

+ * TCP Vegas congestion control
+ *
+ * This is based on the congestion detection/avoidance scheme described in
+ * Lawrence S. Brakmo and Larry L. Peterson.
+ * "TCP Vegas: End to end congestion avoidance on a global internet."
+ * IEEE Journal on Selected Areas in Communication, 13(8):1465--1480,
+ * October 1995. Available from:
+ * ftp://ftp.cs.arizona.edu/xkernel/Papers/jsac.ps
+ *
+ * See http://www.cs.arizona.edu/xkernel/ for their implementation.
+ * The main aspects that distinguish this implementation from the
+ * Arizona Vegas implementation are:
+ * o We do not change the loss detection or recovery mechanisms of
+ * Linux in any way. Linux already recovers from losses quite well,
+ * using fine-grained timers, NewReno, and FACK.
+ * o To avoid the performance penalty imposed by increasing cwnd
+ * only every-other RTT during slow start, we increase during
+ * every RTT during slow start, just like Reno.
+ * o Largely to allow continuous cwnd growth during slow start,
+ * we use the rate at which ACKs come back as the "actual"
+ * rate, rather than the rate at which data is sent.
+ * o To speed convergence to the right rate, we set the cwnd
+ * to achieve the right ("actual") rate when we exit slow start.
+ * o To filter out the noise caused by delayed ACKs, we use the
+ * minimum RTT sample observed during the last RTT to calculate
+ * the actual rate.
+ * o When the sender re-starts from idle, it waits until it has
+ * received ACKs for an entire flight of new data before making
+ * a cwnd adjustment decision. The original Vegas implementation
+ * assumed senders never went idle.

+ *
+ * Original Author:
+ * Aleksandar Kuzmanovic <akuzma@northwestern.edu>
+ *
+ * See http://www-ece.rice.edu/networks/TCP-LP/ for their implementation.
+ * As of 2.6.13, Linux supports pluggable congestion control algorithms.
+ * Due to the limitation of the API, we take the following changes from
+ * the original TCP-LP implementation:
+ * o We use newReno in most core CA handling. Only add some checking
+ * within cong_avoid.
+ * o Error correcting in remote HZ, therefore remote HZ will be keeped
+ * on checking and updating.
+ * o Handling calculation of One-Way-Delay (OWD) within rtt_sample, sicne
+ * OWD have a similar meaning as RTT. Also correct the buggy formular.
+ * o Handle reaction for Early Congestion Indication (ECI) within
+ * pkts_acked, as mentioned within pseudo code.
+ * o OWD is handled in relative format, where local time stamp will in
+ * tcp_time_stamp format.
