+
+PHY device node
+===============
+
+Required Properties:
+#phy-cells: Number of cells in a PHY specifier; The meaning of all those
+ cells is defined by the binding for the phy node. The PHY
+ provider can use the values in cells to find the appropriate
+ PHY.
+
+For example:
+
+phys: phy {
+ compatible = "xxx";
+ reg = <...>;
+ .
+ .
+ #phy-cells = <1>;
+ .
+ .
+};
+
+That node describes an IP block (PHY provider) that implements 2 different PHYs.
+In order to differentiate between these 2 PHYs, an additonal specifier should be
+given while trying to get a reference to it.
+
+PHY user node
+=============
+
+Required Properties:
+phys : the phandle for the PHY device (used by the PHY subsystem)
+phy-names : the names of the PHY corresponding to the PHYs present in the
+ *phys* phandle
+
+Example 1:
+usb1: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&usb2_phy>, <&usb3_phy>;
+ phy-names = "usb2phy", "usb3phy";
+ .
+ .
+};
+
+This node represents a controller that uses two PHYs, one for usb2 and one for
+usb3.
+
+Example 2:
+usb2: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&phys 1>;
+ phy-names = "usbphy";
+ .
+ .
+};
+
+This node represents a controller that uses one of the PHYs of the PHY provider
+device defined previously. Note that the phy handle has an additional specifier
+"1" to differentiate between the two PHYs.

+COOKIE ENABLEMENT
+=================
+
+Cookies exist in one of two states: enabled and disabled. If a cookie is
+disabled, it ignores all attempts to acquire child cookies; check, update or
+invalidate its state; allocate, read or write backing pages - though it is
+still possible to uncache pages and relinquish the cookie.
+
+The initial enablement state is set by fscache_acquire_cookie(), but the cookie
+can be enabled or disabled later. To disable a cookie, call:
+
+ void fscache_disable_cookie(struct fscache_cookie *cookie,
+ bool invalidate);
+
+If the cookie is not already disabled, this locks the cookie against other
+enable and disable ops, marks the cookie as being disabled, discards or
+invalidates any backing objects and waits for cessation of activity on any
+associated object before unlocking the cookie.
+
+All possible failures are handled internally. The caller should consider
+calling fscache_uncache_all_inode_pages() afterwards to make sure all page
+markings are cleared up.
+
+Cookies can be enabled or reenabled with:
+
+ void fscache_enable_cookie(struct fscache_cookie *cookie,
+ bool (*can_enable)(void *data),
+ void *data)
+
+If the cookie is not already enabled, this locks the cookie against other
+enable and disable ops, invokes can_enable() and, if the cookie is not an index

+An Intel MIC X100 device is a PCIe form factor add-in coprocessor
+card based on the Intel Many Integrated Core (MIC) architecture
+that runs a Linux OS. It is a PCIe endpoint in a platform and therefore
+implements the three required standard address spaces i.e. configuration,
+memory and I/O. The host OS loads a device driver as is typical for
+PCIe devices. The card itself runs a bootstrap after reset that
+transfers control to the card OS downloaded from the host driver. The
+host driver supports OSPM suspend and resume operations. It shuts down
+the card during suspend and reboots the card OS during resume.
+The card OS as shipped by Intel is a Linux kernel with modifications
+for the X100 devices.
+
+Since it is a PCIe card, it does not have the ability to host hardware
+devices for networking, storage and console. We provide these devices
+on X100 coprocessors thus enabling a self-bootable equivalent environment
+for applications. A key benefit of our solution is that it leverages
+the standard virtio framework for network, disk and console devices,
+though in our case the virtio framework is used across a PCIe bus.
+
+Here is a block diagram of the various components described above. The
+virtio backends are situated on the host rather than the card given better
+single threaded performance for the host compared to MIC, the ability of
+the host to initiate DMA's to/from the card using the MIC DMA engine and
+the fact that the virtio block storage backend can only be on the host.

+ PHY SUBSYSTEM
+ Kishon Vijay Abraham I <kishon@ti.com>
+
+This document explains the Generic PHY Framework along with the APIs provided,
+and how-to-use.
+
+1. Introduction
+
+*PHY* is the abbreviation for physical layer. It is used to connect a device
+to the physical medium e.g., the USB controller has a PHY to provide functions
+such as serialization, de-serialization, encoding, decoding and is responsible
+for obtaining the required data transmission rate. Note that some USB
+controllers have PHY functionality embedded into it and others use an external
+PHY. Other peripherals that use PHY include Wireless LAN, Ethernet,
+SATA etc.
+
+The intention of creating this framework is to bring the PHY drivers spread
+all over the Linux kernel to drivers/phy to increase code re-use and for
+better code maintainability.
+
+This framework will be of use only to devices that use external PHY (PHY
+functionality is not embedded within the controller).
+
+2. Registering/Unregistering the PHY provider
+
+PHY provider refers to an entity that implements one or more PHY instances.
+For the simple case where the PHY provider implements only a single instance of
+the PHY, the framework provides its own implementation of of_xlate in
+of_phy_simple_xlate. If the PHY provider implements multiple instances, it
+should provide its own implementation of of_xlate. of_xlate is used only for
+dt boot case.
+
+#define of_phy_provider_register(dev, xlate) \
+ __of_phy_provider_register((dev), THIS_MODULE, (xlate))
+
+#define devm_of_phy_provider_register(dev, xlate) \
+ __devm_of_phy_provider_register((dev), THIS_MODULE, (xlate))
+
+of_phy_provider_register and devm_of_phy_provider_register macros can be used to
+register the phy_provider and it takes device and of_xlate as
+arguments. For the dt boot case, all PHY providers should use one of the above
+2 macros to register the PHY provider.
+
+void devm_of_phy_provider_unregister(struct device *dev,
+ struct phy_provider *phy_provider);
+void of_phy_provider_unregister(struct phy_provider *phy_provider);
+
+devm_of_phy_provider_unregister and of_phy_provider_unregister can be used to
+unregister the PHY.
+
+3. Creating the PHY
+
+The PHY driver should create the PHY in order for other peripheral controllers
+to make use of it. The PHY framework provides 2 APIs to create the PHY.
+
+struct phy *phy_create(struct device *dev, const struct phy_ops *ops,
+ struct phy_init_data *init_data);
+struct phy *devm_phy_create(struct device *dev, const struct phy_ops *ops,
+ struct phy_init_data *init_data);
+
+The PHY drivers can use one of the above 2 APIs to create the PHY by passing
+the device pointer, phy ops and init_data.
+phy_ops is a set of function pointers for performing PHY operations such as
+init, exit, power_on and power_off. *init_data* is mandatory to get a reference
+to the PHY in the case of non-dt boot. See section *Board File Initialization*
+on how init_data should be used.
+
+Inorder to dereference the private data (in phy_ops), the phy provider driver
+can use phy_set_drvdata() after creating the PHY and use phy_get_drvdata() in
+phy_ops to get back the private data.
+
+4. Getting a reference to the PHY
+
+Before the controller can make use of the PHY, it has to get a reference to
+it. This framework provides the following APIs to get a reference to the PHY.
+
+struct phy *phy_get(struct device *dev, const char *string);
+struct phy *devm_phy_get(struct device *dev, const char *string);
+
+phy_get and devm_phy_get can be used to get the PHY. In the case of dt boot,
+the string arguments should contain the phy name as given in the dt data and
+in the case of non-dt boot, it should contain the label of the PHY.
+The only difference between the two APIs is that devm_phy_get associates the
+device with the PHY using devres on successful PHY get. On driver detach,
+release function is invoked on the the devres data and devres data is freed.
+
+5. Releasing a reference to the PHY
+
+When the controller no longer needs the PHY, it has to release the reference
+to the PHY it has obtained using the APIs mentioned in the above section. The
+PHY framework provides 2 APIs to release a reference to the PHY.
+
+void phy_put(struct phy *phy);
+void devm_phy_put(struct device *dev, struct phy *phy);
+
+Both these APIs are used to release a reference to the PHY and devm_phy_put
+destroys the devres associated with this PHY.
+
+6. Destroying the PHY
+
+When the driver that created the PHY is unloaded, it should destroy the PHY it
+created using one of the following 2 APIs.
+
+void phy_destroy(struct phy *phy);
+void devm_phy_destroy(struct device *dev, struct phy *phy);
+
+Both these APIs destroy the PHY and devm_phy_destroy destroys the devres
+associated with this PHY.
+
+7. PM Runtime
+
+This subsystem is pm runtime enabled. So while creating the PHY,
+pm_runtime_enable of the phy device created by this subsystem is called and
+while destroying the PHY, pm_runtime_disable is called. Note that the phy
+device created by this subsystem will be a child of the device that calls
+phy_create (PHY provider device).
+
+So pm_runtime_get_sync of the phy_device created by this subsystem will invoke
+pm_runtime_get_sync of PHY provider device because of parent-child relationship.
+It should also be noted that phy_power_on and phy_power_off performs
+phy_pm_runtime_get_sync and phy_pm_runtime_put respectively.
+There are exported APIs like phy_pm_runtime_get, phy_pm_runtime_get_sync,
+phy_pm_runtime_put, phy_pm_runtime_put_sync, phy_pm_runtime_allow and
+phy_pm_runtime_forbid for performing PM operations.
+
+8. Board File Initialization
+
+Certain board file initialization is necessary in order to get a reference
+to the PHY in the case of non-dt boot.
+Say we have a single device that implements 3 PHYs that of USB, SATA and PCIe,
+then in the board file the following initialization should be done.
+
+struct phy_consumer consumers[] = {
+ PHY_CONSUMER("dwc3.0", "usb"),
+ PHY_CONSUMER("pcie.0", "pcie"),
+ PHY_CONSUMER("sata.0", "sata"),
+};
+PHY_CONSUMER takes 2 parameters, first is the device name of the controller
+(PHY consumer) and second is the port name.
+
+struct phy_init_data init_data = {
+ .consumers = consumers,
+ .num_consumers = ARRAY_SIZE(consumers),
+};
+
+static const struct platform_device pipe3_phy_dev = {
+ .name = "pipe3-phy",
+ .id = -1,
+ .dev = {
+ .platform_data = {
+ .init_data = &init_data,
+ },
+ },
+};
+
+then, while doing phy_create, the PHY driver should pass this init_data
+ phy_create(dev, ops, pdata->init_data);
+
+and the controller driver (phy consumer) should pass the port name along with
+the device to get a reference to the PHY
+ phy_get(dev, "pcie");
+
+9. DeviceTree Binding

+The documentation for PHY dt binding can be found @

+PPS with USB to serial devices
+------------------------------
+
+It is possible to grab the PPS from an USB to serial device. However,
+you should take into account the latencies and jitter introduced by
+the USB stack. Users has reported clock instability around +-1ms when
+synchronized with PPS through USB. This isn't suited for time server
+synchronization.
+
+If your device doesn't report PPS, you can check that the feature is
+supported by its driver. Most of the time, you only need to add a call
+to usb_serial_handle_dcd_change after checking the DCD status (see
+ch341 and pl2303 examples).

-/* The head-file for the Shark
- * by Alexander Schulz
- *
- * Does the following:
- * - get the memory layout from firmware. This can only be done as long as the mmu
- * is still on.
- * - switch the mmu off, so we have physical addresses
- * - copy the kernel to 0x08508000. This is done to have a fixed address where the
- * C-parts (misc.c) are executed. This address must be known at compile-time,
- * but the load-address of the kernel depends on how much memory is installed.
- * - Jump to this location.
- * - Set r8 with 0, r7 with the architecture ID for head.S

- * Generate an Ethernet MAC address that has a good chance of being unique.
- * @addr: Pointer to six-byte array containing the Ethernet address
- * Generates an Ethernet MAC address that is highly likely to be unique for
- * this particular system on a network with other systems of the same type.
- *
- * The problem we are solving is that, when eth_random_addr() is used to
- * generate MAC addresses at startup, there isn't much entropy for the random
- * number generator to use and the addresses it produces are fairly likely to
- * be the same as those of other identical systems on the same local network.
- * This is true even for relatively small numbers of systems (for the reason
- * why, see the Wikipedia entry for "Birthday problem" at:
- * http://en.wikipedia.org/wiki/Birthday_problem
- *
- * The good news is that we already have a MAC address known to be unique, the
- * RF MAC address. The bad news is that this address is already in use on the
- * RF interface. Worse, the obvious trick, taking the RF MAC address and
- * turning on the locally managed bit, has already been used for other devices.
- * Still, this does give us something to work with.
- *
- * The approach we take is:
- * 1. If we can't get the RF MAC Address, just call eth_random_addr.
- * 2. Use the 24-bit NIC-specific bits of the RF MAC address as the last 24
- * bits of the new address. This is very likely to be unique, except for
- * the current box.
- * 3. To avoid using addresses already on the current box, we set the top
- * six bits of the address with a value different from any currently
- * registered Scientific Atlanta organizationally unique identifyer
- * (OUI). This avoids duplication with any addresses on the system that
- * were generated from valid Scientific Atlanta-registered address by
- * simply flipping the locally managed bit.
- * 4. We aren't generating a multicast address, so we leave the multicast
- * bit off. Since we aren't using a registered address, we have to set
- * the locally managed bit.
- * 5. We then randomly generate the remaining 16-bits. This does two
- * things:
- * a. It allows us to call this function for more than one device
- * in this system
- * b. It ensures that things will probably still work even if
- * some device on the device network has a locally managed
- * address that matches the top six bits from step 2.

- * Author(s): Martin Schwidefsky (schwidefsky@de.ibm.com)
+ * Copyright IBM Corp. 1999,2013
*
- * Derived from "include/asm-i386/bitops.h"

+ * Author(s): Martin Schwidefsky <schwidefsky@de.ibm.com>,
+ *
+ * The description below was taken in large parts from the powerpc
+ * bitops header file:
+ * Within a word, bits are numbered LSB first. Lot's of places make
+ * this assumption by directly testing bits with (val & (1<<nr)).
+ * This can cause confusion for large (> 1 word) bitmaps on a
+ * big-endian system because, unlike little endian, the number of each
+ * bit depends on the word size.
+ *
+ * The bitop functions are defined to work on unsigned longs, so for an
+ * s390x system the bits end up numbered:
+ * |63..............0|127............64|191...........128|255...........196|
+ * and on s390:
+ * |31.....0|63....31|95....64|127...96|159..128|191..160|223..192|255..224|
+ *
+ * There are a few little-endian macros used mostly for filesystem
+ * bitmaps, these work on similar bit arrays layouts, but
+ * byte-oriented:
+ * |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56|
+ *
+ * The main difference is that bit 3-5 (64b) or 3-4 (32b) in the bit
+ * number field needs to be reversed compared to the big-endian bit
+ * fields. This can be achieved by XOR with 0x38 (64b) or 0x18 (32b).
+ *
+ * We also have special functions which work with an MSB0 encoding:
+ * on an s390x system the bits are numbered:
+ * |0..............63|64............127|128...........191|192...........255|
+ * and on s390:
+ * |0.....31|31....63|64....95|96...127|128..159|160..191|192..223|224..255|
+ *
+ * The main difference is that bit 0-63 (64b) or 0-31 (32b) in the bit
+ * number field needs to be reversed compared to the LSB0 encoded bit
+ * fields. This can be achieved by XOR with 0x3f (64b) or 0x1f (32b).

+ * All of these SoCs have 4 physical channels and the number of request
+ * source bits is 3. Additionally we also need 1 bit to mark the channel
+ * as valid.
+ * Therefore we separate the chansel element of the channel data into 4
+ * parts of 4 bits each, to hold the information if the channel is valid
+ * and the hw request source to use.
+ *
+ * Example:
+ * SDI is valid on channels 0, 2 and 3 - with varying hw request sources.
+ * For it the chansel field would look like
+ *
+ * ((BIT(3) | 1) << 3 * 4) | // channel 3, with request source 1
+ * ((BIT(3) | 2) << 2 * 4) | // channel 2, with request source 2
+ * ((BIT(3) | 2) << 0 * 4) // channel 0, with request source 2

+ *
+ * IIO features supported by the driver:
+ *
+ * Read-only raw channels:
+ * - illiminance_clear [lux]
+ * - illiminance_ir
+ * - proximity
+ *
+ * Triggered buffer:
+ * - illiminance_clear
+ * - illiminance_ir
+ * - proximity
+ *
+ * Events:
+ * - illuminance_clear (rising and falling)
+ * - proximity (rising and falling)
+ * - both falling and rising thresholds for the proximity events
+ * must be set to the values greater than 0.
+ *
+ * The driver supports triggered buffers for all the three
+ * channels as well as high and low threshold events for the
+ * illuminance_clear and proxmimity channels. Triggers
+ * can be enabled simultaneously with both illuminance_clear
+ * events. Proximity events cannot be enabled simultaneously
+ * with any triggers or illuminance events. Enabling/disabling
+ * one of the proximity events automatically enables/disables
+ * the other one.

-Driver: comedi_parport

-Author: ds
-Status: works in immediate mode
-Devices: [standard] parallel port (comedi_parport)
-Updated: Tue, 30 Apr 2002 21:11:45 -0700
-
-A cheap and easy way to get a few more digital I/O lines. Steal
-additional parallel ports from old computers or your neighbors'
-computers.
-
-Option list:
- 0: I/O port base for the parallel port.
- 1: IRQ
-
-Parallel Port Lines:
-
-pin subdev chan aka
---- ------ ---- ---
-1 2 0 strobe
-2 0 0 data 0
-3 0 1 data 1
-4 0 2 data 2
-5 0 3 data 3
-6 0 4 data 4
-7 0 5 data 5
-8 0 6 data 6
-9 0 7 data 7
-10 1 3 acknowledge
-11 1 4 busy
-12 1 2 output
-13 1 1 printer selected
-14 2 1 auto LF
-15 1 0 error
-16 2 2 init
-17 2 3 select printer
-18-25 ground
-
-Notes:
-
-Subdevices 0 is digital I/O, subdevice 1 is digital input, and
-subdevice 2 is digital output. Unlike other Comedi devices,
-subdevice 0 defaults to output.
-
-Pins 13 and 14 are inverted once by Comedi and once by the
-hardware, thus cancelling the effect.
-
-Pin 1 is a strobe, thus acts like one. There's no way in software
-to change this, at least on a standard parallel port.
-
-Subdevice 3 pretends to be a digital input subdevice, but it always
-returns 0 when read. However, if you run a command with
-scan_begin_src=TRIG_EXT, it uses pin 10 as a external triggering
-pin, which can be used to wake up tasks.

-Driver: pcl711
-Description: Advantech PCL-711 and 711b, ADLink ACL-8112
-Author: ds, Janne Jalkanen <jalkanen@cs.hut.fi>, Eric Bunn <ebu@cs.hut.fi>
-Status: mostly complete
-Devices: [Advantech] PCL-711 (pcl711), PCL-711B (pcl711b),
- [AdLink] ACL-8112HG (acl8112hg), ACL-8112DG (acl8112dg)
-
-Since these boards do not have DMA or FIFOs, only immediate mode is
-supported.
-
-*/
/*
- Dave Andruczyk <dave@tech.buffalostate.edu> also wrote a
- driver for the PCL-711. I used a few ideas from his driver
- here. His driver also has more comments, if you are
- interested in understanding how this driver works.
- http://tech.buffalostate.edu/~dave/driver/
-
- The ACL-8112 driver was hacked from the sources of the PCL-711
- driver (the 744 chip used on the 8112 is almost the same as
- the 711b chip, but it has more I/O channels) by
- Janne Jalkanen (jalkanen@cs.hut.fi) and
- Erik Bunn (ebu@cs.hut.fi). Remerged with the PCL-711 driver
- by ds.
-
- [acl-8112]
- This driver supports both TRIGNOW and TRIGCLK,
- but does not yet support DMA transfers. It also supports
- both high (HG) and low (DG) versions of the card, though
- the HG version has been untested.

+TODO:
+ - Dan Carpenter would like to see some cleanups to the microframe
+ scheduler code:
+ http://www.mail-archive.com/linux-usb@vger.kernel.org/msg26650.html
+
+ - Should merge the NAK holdoff patch from Raspberry Pi
+ (http://marc.info/?l=linux-usb&m=137625067103833). But as it stands
+ that patch is incomplete, it needs more investigation to see if it
+ can be made to work for non-Raspberry Pi platforms that lack the
+ special FIQ interrupt that the Pi has. Without this patch, the driver
+ has a high interrupt rate (8K/sec).
+
+ - The Raspberry Pi platform needs to have support for its FIQ interrupt
+ added, to get the same level of functionality as the downstream
+ driver. The raspberrypi.org developers have indicated they are
+ willing to help with that.
+
+ - Some of the default driver parameters (see 'struct dwc2_core_params'
+ in core.h) won't work for many platforms. So DT attributes will need
+ to be added for some of these. But that can be done as-needed as new
+ platforms are added.
+
+ - Eventually the driver should be merged with the s3c-hsotg peripheral
+ mode driver, so that both modes of operation can be supported with a
+ single driver. But I think that can wait till after the driver has
+ been moved to mainline.
+
+ - After that, OTG support can be added. I'm not sure how much demand
+ there is for that, though, so I have that as a low priority.
+
+Please send any patches for this driver to Paul Zimmerman <paulz@synopsys.com>
+and Greg Kroah-Hartman <gregkh@linuxfoundation.org>. And please CC linux-usb
+<linux-usb@vger.kernel.org> too.

-/**
- * "cvmx-usb.h" defines a set of low level USB functions to help
- * developers create Octeon USB drivers for various operating
- * systems. These functions provide a generic API to the Octeon
- * USB blocks, hiding the internal hardware specific
- * operations.
- *
- * At a high level the device driver needs to:
- *
- * - Call cvmx_usb_get_num_ports() to get the number of
- * supported ports.
- * - Call cvmx_usb_initialize() for each Octeon USB port.
- * - Enable the port using cvmx_usb_enable().
- * - Either periodically, or in an interrupt handler, call
- * cvmx_usb_poll() to service USB events.
- * - Manage pipes using cvmx_usb_open_pipe() and
- * cvmx_usb_close_pipe().
- * - Manage transfers using cvmx_usb_submit_*() and
- * cvmx_usb_cancel*().
- * - Shutdown USB on unload using cvmx_usb_shutdown().
- *
- * To monitor USB status changes, the device driver must use
- * cvmx_usb_register_callback() to register for events that it
- * is interested in. Below are a few hints on successfully
- * implementing a driver on top of this API.
- *
- * == Initialization ==
- *
- * When a driver is first loaded, it is normally not necessary
- * to bring up the USB port completely. Most operating systems
- * expect to initialize and enable the port in two independent
- * steps. Normally an operating system will probe hardware,
- * initialize anything found, and then enable the hardware.
- *
- * In the probe phase you should:
- * - Use cvmx_usb_get_num_ports() to determine the number of
- * USB port to be supported.
- * - Allocate space for a struct cvmx_usb_state for each
- * port.
- * - Tell the operating system about each port
- *
- * In the initialization phase you should:
- * - Use cvmx_usb_initialize() on each port.
- * - Do not call cvmx_usb_enable(). This leaves the USB port in
- * the disabled state until the operating system is ready.
- *
- * Finally, in the enable phase you should:
- * - Call cvmx_usb_enable() on the appropriate port.
- * - Note that some operating system use a RESET instead of an
- * enable call. To implement RESET, you should call
- * cvmx_usb_disable() followed by cvmx_usb_enable().
- *
- * == Locking ==
- *
- * All of the functions in the cvmx-usb API assume exclusive
- * access to the USB hardware and internal data structures. This
- * means that the driver must provide locking as necessary.
- *
- * In the single CPU state it is normally enough to disable
- * interrupts before every call to cvmx_usb*() and enable them
- * again after the call is complete. Keep in mind that it is
- * very common for the callback handlers to make additional
- * calls into cvmx-usb, so the disable/enable must be protected
- * against recursion. As an example, the Linux kernel
- * local_irq_save() and local_irq_restore() are perfect for this
- * in the non SMP case.
- *
- * In the SMP case, locking is more complicated. For SMP you not
- * only need to disable interrupts on the local core, but also
- * take a lock to make sure that another core cannot call
- * cvmx-usb.
- *
- * == Port callback ==
- *
- * The port callback prototype needs to look as follows:
- *
- * void port_callback(struct cvmx_usb_state *usb,
- * enum cvmx_usb_callback reason,
- * enum cvmx_usb_complete status,
- * int pipe_handle,
- * int submit_handle,
- * int bytes_transferred,
- * void *user_data);
- * - "usb" is the struct cvmx_usb_state for the port.
- * - "reason" will always be CVMX_USB_CALLBACK_PORT_CHANGED.
- * - "status" will always be CVMX_USB_COMPLETE_SUCCESS.
- * - "pipe_handle" will always be -1.
- * - "submit_handle" will always be -1.
- * - "bytes_transferred" will always be 0.
- * - "user_data" is the void pointer originally passed along
- * with the callback. Use this for any state information you
- * need.
- *
- * The port callback will be called whenever the user plugs /
- * unplugs a device from the port. It will not be called when a
- * device is plugged / unplugged from a hub connected to the
- * root port. Normally all the callback needs to do is tell the
- * operating system to poll the root hub for status. Under
- * Linux, this is performed by calling usb_hcd_poll_rh_status().
- * In the Linux driver we use "user_data". to pass around the
- * Linux "hcd" structure. Once the port callback completes,
- * Linux automatically calls octeon_usb_hub_status_data() which
- * uses cvmx_usb_get_status() to determine the root port status.
- *
- * == Complete callback ==
- *
- * The completion callback prototype needs to look as follows:
- *
- * void complete_callback(struct cvmx_usb_state *usb,
- * enum cvmx_usb_callback reason,
- * enum cvmx_usb_complete status,
- * int pipe_handle,
- * int submit_handle,
- * int bytes_transferred,
- * void *user_data);
- * - "usb" is the struct cvmx_usb_state for the port.
- * - "reason" will always be CVMX_USB_CALLBACK_TRANSFER_COMPLETE.
- * - "status" will be one of the cvmx_usb_complete enumerations.
- * - "pipe_handle" is the handle to the pipe the transaction
- * was originally submitted on.
- * - "submit_handle" is the handle returned by the original
- * cvmx_usb_submit_* call.
- * - "bytes_transferred" is the number of bytes successfully
- * transferred in the transaction. This will be zero on most
- * error conditions.
- * - "user_data" is the void pointer originally passed along
- * with the callback. Use this for any state information you
- * need. For example, the Linux "urb" is stored in here in the
- * Linux driver.
- *
- * In general your callback handler should use "status" and
- * "bytes_transferred" to tell the operating system the how the
- * transaction completed. Normally the pipe is not changed in
- * this callback.
- *
- * == Canceling transactions ==
- *
- * When a transaction is cancelled using cvmx_usb_cancel*(), the
- * actual length of time until the complete callback is called
- * can vary greatly. It may be called before cvmx_usb_cancel*()
- * returns, or it may be called a number of usb frames in the
- * future once the hardware frees the transaction. In either of
- * these cases, the complete handler will receive
- * CVMX_USB_COMPLETE_CANCEL.
- *
- * == Handling pipes ==
- *
- * USB "pipes" is a software construct created by this API to
- * enable the ordering of usb transactions to a device endpoint.
- * Octeon's underlying hardware doesn't have any concept
- * equivalent to "pipes". The hardware instead has eight
- * channels that can be used simultaneously to have up to eight
- * transaction in process at the same time. In order to maintain
- * ordering in a pipe, the transactions for a pipe will only be
- * active in one hardware channel at a time. From an API user's
- * perspective, this doesn't matter but it can be helpful to
- * keep this in mind when you are probing hardware while
- * debugging.
- *
- * Also keep in mind that usb transactions contain state
- * information about the previous transaction to the same
- * endpoint. Each transaction has a PID toggle that changes 0/1
- * between each sub packet. This is maintained in the pipe data
- * structures. For this reason, you generally cannot create and
- * destroy a pipe for every transaction. A sequence of
- * transaction to the same endpoint must use the same pipe.
- *
- * == Root Hub ==
- *
- * Some operating systems view the usb root port as a normal usb
- * hub. These systems attempt to control the root hub with
- * messages similar to the usb 2.0 spec for hub control and
- * status. For these systems it may be necessary to write
- * function to decode standard usb control messages into
- * equivalent cvmx-usb API calls.
- *
- * == Interrupts ==
- *
- * If you plan on using usb interrupts, cvmx_usb_poll() must be
- * called on every usb interrupt. It will read the usb state,
- * call any needed callbacks, and schedule transactions as
- * needed. Your device driver needs only to hookup an interrupt
- * handler and call cvmx_usb_poll(). Octeon's usb port 0 causes
- * CIU bit CIU_INT*_SUM0[USB] to be set (bit 56). For port 1,
- * CIU bit CIU_INT_SUM1[USB1] is set (bit 17). How these bits
- * are turned into interrupt numbers is operating system
- * specific. For Linux, there are the convenient defines
- * OCTEON_IRQ_USB0 and OCTEON_IRQ_USB1 for the IRQ numbers.
- *
- * If you aren't using interrupts, simple call cvmx_usb_poll()
- * in your main processing loop.

+ * kcore_copy - copy kallsyms, modules and kcore from one directory to another.
+ * @from_dir: from directory
+ * @to_dir: to directory
+ *
+ * This function copies kallsyms, modules and kcore files from one directory to
+ * another. kallsyms and modules are copied entirely. Only code segments are
+ * copied from kcore. It is assumed that two segments suffice: one for the
+ * kernel proper and one for all the modules. The code segments are determined
+ * from kallsyms and modules files. The kernel map starts at _stext or the
+ * lowest function symbol, and ends at _etext or the highest function symbol.
+ * The module map starts at the lowest module address and ends at the highest
+ * module symbol. Start addresses are rounded down to the nearest page. End
+ * addresses are rounded up to the nearest page. An extra page is added to the
+ * highest kernel symbol and highest module symbol to, hopefully, encompass that
+ * symbol too. Because it contains only code sections, the resulting kcore is
+ * unusual. One significant peculiarity is that the mapping (start -> pgoff)
+ * is not the same for the kernel map and the modules map. That happens because
+ * the data is copied adjacently whereas the original kcore has gaps. Finally,
+ * kallsyms and modules files are compared with their copies to check that
+ * modules have not been loaded or unloaded while the copies were taking place.
+ *
+ * Return: %0 on success, %-1 on failure.
