+Kernel driver lp3944
+====================
+
+ * National Semiconductor LP3944 Fun-light Chip
+ Prefix: 'lp3944'
+ Addresses scanned: None (see the Notes section below)
+ Datasheet: Publicly available at the National Semiconductor website
+ http://www.national.com/pf/LP/LP3944.html
+
+Authors:
+ Antonio Ospite <ospite@studenti.unina.it>
+
+
+Description
+-----------
+The LP3944 is a helper chip that can drive up to 8 leds, with two programmable
+DIM modes; it could even be used as a gpio expander but this driver assumes it
+is used as a led controller.
+
+The DIM modes are used to set _blink_ patterns for leds, the pattern is
+specified supplying two parameters:
+ - period: from 0s to 1.6s
+ - duty cycle: percentage of the period the led is on, from 0 to 100
+
+Setting a led in DIM0 or DIM1 mode makes it blink according to the pattern.
+See the datasheet for details.
+
+LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
+leds, the camera flash light and the lcds power.
+
+
+Notes
+-----
+The chip is used mainly in embedded contexts, so this driver expects it is
+registered using the i2c_board_info mechanism.
+
+To register the chip at address 0x60 on adapter 0, set the platform data
+according to include/linux/leds-lp3944.h, set the i2c board info:
+
+ static struct i2c_board_info __initdata a910_i2c_board_info[] = {
+ {
+ I2C_BOARD_INFO("lp3944", 0x60),
+ .platform_data = &a910_lp3944_leds,
+ },
+ };
+
+and register it in the platform init function
+
+ i2c_register_board_info(0, a910_i2c_board_info,
+ ARRAY_SIZE(a910_i2c_board_info));

platforms are moved over to use the flattened-device-tree model.
- a) PHY nodes
-
- Required properties:
-
- - device_type : Should be "ethernet-phy"
- - interrupts : <a b> where a is the interrupt number and b is a
- field that represents an encoding of the sense and level
- information for the interrupt. This should be encoded based on
- the information in section 2) depending on the type of interrupt
- controller you have.
- - interrupt-parent : the phandle for the interrupt controller that
- services interrupts for this device.
- - reg : The ID number for the phy, usually a small integer
- - linux,phandle : phandle for this node; likely referenced by an
- ethernet controller node.

-
-
- b) Interrupt controllers
-
- Some SOC devices contain interrupt controllers that are different
- from the standard Open PIC specification. The SOC device nodes for
- these types of controllers should be specified just like a standard
- OpenPIC controller. Sense and level information should be encoded
- as specified in section 2) of this chapter for each device that
- specifies an interrupt.
-
- Example :
-
- pic@40000 {
- linux,phandle = <40000>;
- interrupt-controller;
- #address-cells = <0>;
- reg = <40000 40000>;

-
- c) 4xx/Axon EMAC ethernet nodes
-
- The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
- the Axon bridge. To operate this needs to interact with a ths
- special McMAL DMA controller, and sometimes an RGMII or ZMII
- interface. In addition to the nodes and properties described
- below, the node for the OPB bus on which the EMAC sits must have a
- correct clock-frequency property.
-
- i) The EMAC node itself
-
- Required properties:
- - device_type : "network"
-
- - compatible : compatible list, contains 2 entries, first is
- "ibm,emac-CHIP" where CHIP is the host ASIC (440gx,
- 405gp, Axon) and second is either "ibm,emac" or
- "ibm,emac4". For Axon, thus, we have: "ibm,emac-axon",
- "ibm,emac4"

- "tbi", "gmii", rtbi", "sgmii".
- For Axon on CAB, it is "rgmii"
- - mdio-device : 1 cell, required iff using shared MDIO registers
- (440EP). phandle of the EMAC to use to drive the
- MDIO lines for the PHY used by this EMAC.
- - zmii-device : 1 cell, required iff connected to a ZMII. phandle of
- the ZMII device node
- - zmii-channel : 1 cell, required iff connected to a ZMII. Which ZMII
- channel or 0xffffffff if ZMII is only used for MDIO.
- - rgmii-device : 1 cell, required iff connected to an RGMII. phandle
- of the RGMII device node.
- For Axon: phandle of plb5/plb4/opb/rgmii
- - rgmii-channel : 1 cell, required iff connected to an RGMII. Which
- RGMII channel is used by this EMAC.
- Fox Axon: present, whatever value is appropriate for each
- EMAC, that is the content of the current (bogus) "phy-port"
- property.

- Optional properties:
- - phy-address : 1 cell, optional, MDIO address of the PHY. If absent,
- a search is performed.
- - phy-map : 1 cell, optional, bitmap of addresses to probe the PHY
- for, used if phy-address is absent. bit 0x00000001 is
- MDIO address 0.
- For Axon it can be absent, though my current driver
- doesn't handle phy-address yet so for now, keep
- 0x00ffffff in it.
- - rx-fifo-size-gige : 1 cell, Rx fifo size in bytes for 1000 Mb/sec
- operations (if absent the value is the same as

- ii) McMAL node
-
- Required properties:
- - device_type : "dma-controller"
- - compatible : compatible list, containing 2 entries, first is

- For Axon, "ibm,mcmal-axon","ibm,mcmal2"
- - interrupts : <interrupt mapping for the MAL interrupts sources:
- 5 sources: tx_eob, rx_eob, serr, txde, rxde>.
- For Axon: This is _different_ from the current
- firmware. We use the "delayed" interrupts for txeob
- and rxeob. Thus we end up with mapping those 5 MPIC
- interrupts, all level positive sensitive: 10, 11, 32,
- 33, 34 (in decimal)
- - dcr-reg : < DCR registers range >
- - dcr-parent : if needed for dcr-reg

-
- Required properties:
- - compatible : compatible list, containing 2 entries, first is
- "ibm,zmii-CHIP" where CHIP is the host ASIC (like
- EMAC) and the second is "ibm,zmii".
- For Axon, there is no ZMII node.
- - reg : <registers mapping>
-
- iv) RGMII node
-
- Required properties:
- - compatible : compatible list, containing 2 entries, first is
- "ibm,rgmii-CHIP" where CHIP is the host ASIC (like
- EMAC) and the second is "ibm,rgmii".
- For Axon, "ibm,rgmii-axon","ibm,rgmii"
- - reg : <registers mapping>
- - revision : as provided by the RGMII new version register if

- For Axon: 0x0000012a
-
- d) Xilinx IP cores
-
- The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
- in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
- of standard device types (network, serial, etc.) and miscellaneous
- devices (gpio, LCD, spi, etc). Also, since these devices are
- implemented within the fpga fabric every instance of the device can be
- synthesised with different options that change the behaviour.
-
- Each IP-core has a set of parameters which the FPGA designer can use to
- control how the core is synthesized. Historically, the EDK tool would
- extract the device parameters relevant to device drivers and copy them
- into an 'xparameters.h' in the form of #define symbols. This tells the
- device drivers how the IP cores are configured, but it requres the kernel
- to be recompiled every time the FPGA bitstream is resynthesized.
-
- The new approach is to export the parameters into the device tree and
- generate a new device tree each time the FPGA bitstream changes. The
- parameters which used to be exported as #defines will now become
- properties of the device node. In general, device nodes for IP-cores
- will take the following form:
-
- (name): (generic-name)@(base-address) {
- compatible = "xlnx,(ip-core-name)-(HW_VER)"
- [, (list of compatible devices), ...];
- reg = <(baseaddr) (size)>;
- interrupt-parent = <&interrupt-controller-phandle>;
- interrupts = < ... >;
- xlnx,(parameter1) = "(string-value)";
- xlnx,(parameter2) = <(int-value)>;
- };
-
- (generic-name): an open firmware-style name that describes the
- generic class of device. Preferably, this is one word, such
- as 'serial' or 'ethernet'.
- (ip-core-name): the name of the ip block (given after the BEGIN
- directive in system.mhs). Should be in lowercase
- and all underscores '_' converted to dashes '-'.
- (name): is derived from the "PARAMETER INSTANCE" value.
- (parameter#): C_* parameters from system.mhs. The C_ prefix is
- dropped from the parameter name, the name is converted
- to lowercase and all underscore '_' characters are
- converted to dashes '-'.
- (baseaddr): the baseaddr parameter value (often named C_BASEADDR).
- (HW_VER): from the HW_VER parameter.
- (size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
-
- Typically, the compatible list will include the exact IP core version
- followed by an older IP core version which implements the same
- interface or any other device with the same interface.
-
- 'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
-
- For example, the following block from system.mhs:
-
- BEGIN opb_uartlite
- PARAMETER INSTANCE = opb_uartlite_0
- PARAMETER HW_VER = 1.00.b
- PARAMETER C_BAUDRATE = 115200
- PARAMETER C_DATA_BITS = 8
- PARAMETER C_ODD_PARITY = 0
- PARAMETER C_USE_PARITY = 0
- PARAMETER C_CLK_FREQ = 50000000
- PARAMETER C_BASEADDR = 0xEC100000
- PARAMETER C_HIGHADDR = 0xEC10FFFF
- BUS_INTERFACE SOPB = opb_7
- PORT OPB_Clk = CLK_50MHz
- PORT Interrupt = opb_uartlite_0_Interrupt
- PORT RX = opb_uartlite_0_RX
- PORT TX = opb_uartlite_0_TX
- PORT OPB_Rst = sys_bus_reset_0
- END
-
- becomes the following device tree node:
-
- opb_uartlite_0: serial@ec100000 {
- device_type = "serial";
- compatible = "xlnx,opb-uartlite-1.00.b";
- reg = <ec100000 10000>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <1 0>; // got this from the opb_intc parameters
- current-speed = <d#115200>; // standard serial device prop
- clock-frequency = <d#50000000>; // standard serial device prop
- xlnx,data-bits = <8>;
- xlnx,odd-parity = <0>;
- xlnx,use-parity = <0>;
- };
-
- Some IP cores actually implement 2 or more logical devices. In
- this case, the device should still describe the whole IP core with
- a single node and add a child node for each logical device. The
- ranges property can be used to translate from parent IP-core to the
- registers of each device. In addition, the parent node should be
- compatible with the bus type 'xlnx,compound', and should contain
- #address-cells and #size-cells, as with any other bus. (Note: this
- makes the assumption that both logical devices have the same bus
- binding. If this is not true, then separate nodes should be used
- for each logical device). The 'cell-index' property can be used to
- enumerate logical devices within an IP core. For example, the
- following is the system.mhs entry for the dual ps2 controller found
- on the ml403 reference design.
-
- BEGIN opb_ps2_dual_ref
- PARAMETER INSTANCE = opb_ps2_dual_ref_0
- PARAMETER HW_VER = 1.00.a
- PARAMETER C_BASEADDR = 0xA9000000
- PARAMETER C_HIGHADDR = 0xA9001FFF
- BUS_INTERFACE SOPB = opb_v20_0
- PORT Sys_Intr1 = ps2_1_intr
- PORT Sys_Intr2 = ps2_2_intr
- PORT Clkin1 = ps2_clk_rx_1
- PORT Clkin2 = ps2_clk_rx_2
- PORT Clkpd1 = ps2_clk_tx_1
- PORT Clkpd2 = ps2_clk_tx_2
- PORT Rx1 = ps2_d_rx_1
- PORT Rx2 = ps2_d_rx_2
- PORT Txpd1 = ps2_d_tx_1
- PORT Txpd2 = ps2_d_tx_2
- END
-
- It would result in the following device tree nodes:
-
- opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "xlnx,compound";
- ranges = <0 a9000000 2000>;
- // If this device had extra parameters, then they would
- // go here.
- ps2@0 {
- compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
- reg = <0 40>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <3 0>;
- cell-index = <0>;
- };
- ps2@1000 {
- compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
- reg = <1000 40>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <3 0>;
- cell-index = <0>;
- };
- };
-
- Also, the system.mhs file defines bus attachments from the processor
- to the devices. The device tree structure should reflect the bus
- attachments. Again an example; this system.mhs fragment:
-
- BEGIN ppc405_virtex4
- PARAMETER INSTANCE = ppc405_0
- PARAMETER HW_VER = 1.01.a
- BUS_INTERFACE DPLB = plb_v34_0
- BUS_INTERFACE IPLB = plb_v34_0
- END
-
- BEGIN opb_intc
- PARAMETER INSTANCE = opb_intc_0
- PARAMETER HW_VER = 1.00.c
- PARAMETER C_BASEADDR = 0xD1000FC0
- PARAMETER C_HIGHADDR = 0xD1000FDF
- BUS_INTERFACE SOPB = opb_v20_0
- END
-
- BEGIN opb_uart16550

- };
- };
- };
-
- That covers the general approach to binding xilinx IP cores into the
- device tree. The following are bindings for specific devices:
-
- i) Xilinx ML300 Framebuffer
-
- Simple framebuffer device from the ML300 reference design (also on the
- ML403 reference design as well as others).
-
- Optional properties:
- - resolution = <xres yres> : pixel resolution of framebuffer. Some
- implementations use a different resolution.
- Default is <d#640 d#480>
- - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
- Default is <d#1024 d#480>.
- - rotate-display (empty) : rotate display 180 degrees.
-
- ii) Xilinx SystemACE
-
- The Xilinx SystemACE device is used to program FPGAs from an FPGA
- bitstream stored on a CF card. It can also be used as a generic CF
- interface device.
-
- Optional properties:
- - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
-
- iii) Xilinx EMAC and Xilinx TEMAC
-
- Xilinx Ethernet devices. In addition to general xilinx properties
- listed above, nodes for these devices should include a phy-handle
- property, and may include other common network device properties
- like local-mac-address.
-
- iv) Xilinx Uartlite
-
- Xilinx uartlite devices are simple fixed speed serial ports.
-
- Required properties:
- - current-speed : Baud rate of uartlite
-
- v) Xilinx hwicap
-
- Xilinx hwicap devices provide access to the configuration logic
- of the FPGA through the Internal Configuration Access Port
- (ICAP). The ICAP enables partial reconfiguration of the FPGA,
- readback of the configuration information, and some control over
- 'warm boots' of the FPGA fabric.
-
- Required properties:
- - xlnx,family : The family of the FPGA, necessary since the
- capabilities of the underlying ICAP hardware
- differ between different families. May be
- 'virtex2p', 'virtex4', or 'virtex5'.
-
- vi) Xilinx Uart 16550
-
- Xilinx UART 16550 devices are very similar to the NS16550 but with
- different register spacing and an offset from the base address.
-
- Required properties:
- - clock-frequency : Frequency of the clock input
- - reg-offset : A value of 3 is required
- - reg-shift : A value of 2 is required
-
- e) USB EHCI controllers
-
- Required properties:
- - compatible : should be "usb-ehci".
- - reg : should contain at least address and length of the standard EHCI
- register set for the device. Optional platform-dependent registers
- (debug-port or other) can be also specified here, but only after
- definition of standard EHCI registers.
- - interrupts : one EHCI interrupt should be described here.
- If device registers are implemented in big endian mode, the device
- node should have "big-endian-regs" property.
- If controller implementation operates with big endian descriptors,
- "big-endian-desc" property should be specified.
- If both big endian registers and descriptors are used by the controller
- implementation, "big-endian" property can be specified instead of having
- both "big-endian-regs" and "big-endian-desc".
-
- Example (Sequoia 440EPx):
- ehci@e0000300 {
- compatible = "ibm,usb-ehci-440epx", "usb-ehci";
- interrupt-parent = <&UIC0>;
- interrupts = <1a 4>;
- reg = <0 e0000300 90 0 e0000390 70>;
- big-endian;
- };
-
- f) MDIO on GPIOs
-
- Currently defined compatibles:
- - virtual,gpio-mdio
-
- MDC and MDIO lines connected to GPIO controllers are listed in the
- gpios property as described in section VIII.1 in the following order:
-
- MDC, MDIO.
-
- Example:
-
- mdio {
- compatible = "virtual,mdio-gpio";
- #address-cells = <1>;
- #size-cells = <0>;
- gpios = <&qe_pio_a 11
- &qe_pio_c 6>;
- };
-
- g) SPI (Serial Peripheral Interface) busses
-
- SPI busses can be described with a node for the SPI master device
- and a set of child nodes for each SPI slave on the bus. For this
- discussion, it is assumed that the system's SPI controller is in
- SPI master mode. This binding does not describe SPI controllers
- in slave mode.
-
- The SPI master node requires the following properties:
- - #address-cells - number of cells required to define a chip select
- address on the SPI bus.
- - #size-cells - should be zero.
- - compatible - name of SPI bus controller following generic names
- recommended practice.
- No other properties are required in the SPI bus node. It is assumed
- that a driver for an SPI bus device will understand that it is an SPI bus.
- However, the binding does not attempt to define the specific method for
- assigning chip select numbers. Since SPI chip select configuration is
- flexible and non-standardized, it is left out of this binding with the
- assumption that board specific platform code will be used to manage
- chip selects. Individual drivers can define additional properties to
- support describing the chip select layout.
-
- SPI slave nodes must be children of the SPI master node and can
- contain the following properties.
- - reg - (required) chip select address of device.
- - compatible - (required) name of SPI device following generic names
- recommended practice
- - spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
- - spi-cpol - (optional) Empty property indicating device requires
- inverse clock polarity (CPOL) mode
- - spi-cpha - (optional) Empty property indicating device requires
- shifted clock phase (CPHA) mode
- - spi-cs-high - (optional) Empty property indicating device requires
- chip select active high
-
- SPI example for an MPC5200 SPI bus:
- spi@f00 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi";
- reg = <0xf00 0x20>;
- interrupts = <2 13 0 2 14 0>;
- interrupt-parent = <&mpc5200_pic>;
-
- ethernet-switch@0 {
- compatible = "micrel,ks8995m";
- spi-max-frequency = <1000000>;
- reg = <0>;
- };
-
- codec@1 {
- compatible = "ti,tlv320aic26";
- spi-max-frequency = <100000>;
- reg = <1>;
- };

-VII - Marvell Discovery mv64[345]6x System Controller chips
-===========================================================
-
-The Marvell mv64[345]60 series of system controller chips contain
-many of the peripherals needed to implement a complete computer
-system. In this section, we define device tree nodes to describe
-the system controller chip itself and each of the peripherals
-which it contains. Compatible string values for each node are
-prefixed with the string "marvell,", for Marvell Technology Group Ltd.
-
-1) The /system-controller node
-
- This node is used to represent the system-controller and must be
- present when the system uses a system controller chip. The top-level
- system-controller node contains information that is global to all
- devices within the system controller chip. The node name begins
- with "system-controller" followed by the unit address, which is
- the base address of the memory-mapped register set for the system
- controller chip.
-
- Required properties:
-
- - ranges : Describes the translation of system controller addresses
- for memory mapped registers.
- - clock-frequency: Contains the main clock frequency for the system
- controller chip.
- - reg : This property defines the address and size of the
- memory-mapped registers contained within the system controller
- chip. The address specified in the "reg" property should match
- the unit address of the system-controller node.
- - #address-cells : Address representation for system controller
- devices. This field represents the number of cells needed to
- represent the address of the memory-mapped registers of devices
- within the system controller chip.
- - #size-cells : Size representation for for the memory-mapped
- registers within the system controller chip.
- - #interrupt-cells : Defines the width of cells used to represent
- interrupts.
-
- Optional properties:
-

- as, "mv64360", "mv64460", or "mv64560".
- - compatible : A string identifying the compatibility identifiers
- of the system controller chip.
-
- The system-controller node contains child nodes for each system
- controller device that the platform uses. Nodes should not be created
- for devices which exist on the system controller chip but are not used
-
- Example Marvell Discovery mv64360 system-controller node:
-
- system-controller@f1000000 { /* Marvell Discovery mv64360 */
- #address-cells = <1>;
- #size-cells = <1>;
- model = "mv64360"; /* Default */
- compatible = "marvell,mv64360";
- clock-frequency = <133333333>;
- reg = <0xf1000000 0x10000>;
- virtual-reg = <0xf1000000>;
- ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
- 0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
- 0xa0000000 0xa0000000 0x4000000 /* User FLASH */

-
-2) Child nodes of /system-controller
-
- a) Marvell Discovery MDIO bus
-
- The MDIO is a bus to which the PHY devices are connected. For each
- device that exists on this bus, a child node should be created. See

-
- b) Marvell Discovery ethernet controller
-
- The Discover ethernet controller is described with two levels
- of nodes. The first level describes an ethernet silicon block
- and the second level describes up to 3 ethernet nodes within

- registers for the node are interleaved within a single set
- of registers. The "ethernet-block" level describes the
- shared register set, and the "ethernet" nodes describe ethernet
- port-specific properties.

+ 4xx/Axon EMAC ethernet nodes
+
+ The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
+ the Axon bridge. To operate this needs to interact with a ths
+ special McMAL DMA controller, and sometimes an RGMII or ZMII
+ interface. In addition to the nodes and properties described
+ below, the node for the OPB bus on which the EMAC sits must have a
+ correct clock-frequency property.

+ - mdio-device : 1 cell, required iff using shared MDIO registers
+ (440EP). phandle of the EMAC to use to drive the

+Marvell Discovery mv64[345]6x System Controller chips
+===========================================================
+
+The Marvell mv64[345]60 series of system controller chips contain
+many of the peripherals needed to implement a complete computer
+system. In this section, we define device tree nodes to describe
+the system controller chip itself and each of the peripherals
+which it contains. Compatible string values for each node are
+prefixed with the string "marvell,", for Marvell Technology Group Ltd.
+
+1) The /system-controller node
+
+ This node is used to represent the system-controller and must be
+ present when the system uses a system controller chip. The top-level
+ system-controller node contains information that is global to all
+ devices within the system controller chip. The node name begins
+ with "system-controller" followed by the unit address, which is
+ the base address of the memory-mapped register set for the system
+ controller chip.
+
+ Required properties:
+
+ - ranges : Describes the translation of system controller addresses
+ for memory mapped registers.
+ - clock-frequency: Contains the main clock frequency for the system
+ controller chip.
+ - reg : This property defines the address and size of the
+ memory-mapped registers contained within the system controller
+ chip. The address specified in the "reg" property should match
+ the unit address of the system-controller node.
+ - #address-cells : Address representation for system controller
+ devices. This field represents the number of cells needed to
+ represent the address of the memory-mapped registers of devices
+ within the system controller chip.
+ - #size-cells : Size representation for for the memory-mapped
+ registers within the system controller chip.
+ - #interrupt-cells : Defines the width of cells used to represent
+ interrupts.
+
+ Optional properties:
+
+ - model : The specific model of the system controller chip. Such
+ as, "mv64360", "mv64460", or "mv64560".
+ - compatible : A string identifying the compatibility identifiers
+ of the system controller chip.
+
+ The system-controller node contains child nodes for each system
+ controller device that the platform uses. Nodes should not be created
+ for devices which exist on the system controller chip but are not used
+
+ Example Marvell Discovery mv64360 system-controller node:
+
+ system-controller@f1000000 { /* Marvell Discovery mv64360 */
+ #address-cells = <1>;
+ #size-cells = <1>;
+ model = "mv64360"; /* Default */
+ compatible = "marvell,mv64360";
+ clock-frequency = <133333333>;
+ reg = <0xf1000000 0x10000>;
+ virtual-reg = <0xf1000000>;
+ ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
+ 0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
+ 0xa0000000 0xa0000000 0x4000000 /* User FLASH */
+ 0x00000000 0xf1000000 0x0010000 /* Bridge's regs */
+ 0xf2000000 0xf2000000 0x0040000>;/* Integrated SRAM */
+
+ [ child node definitions... ]
+ }
+
+2) Child nodes of /system-controller
+
+ a) Marvell Discovery MDIO bus
+
+ The MDIO is a bus to which the PHY devices are connected. For each
+ device that exists on this bus, a child node should be created. See
+ the definition of the PHY node below for an example of how to define
+ a PHY.
+
+ Required properties:
+ - #address-cells : Should be <1>
+ - #size-cells : Should be <0>
+ - device_type : Should be "mdio"
+ - compatible : Should be "marvell,mv64360-mdio"

+ Example:
+
+ mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ device_type = "mdio";
+ compatible = "marvell,mv64360-mdio";
+
+ ethernet-phy@0 {
+ ......
+ };
+ };
+
+
+ b) Marvell Discovery ethernet controller
+
+ The Discover ethernet controller is described with two levels
+ of nodes. The first level describes an ethernet silicon block
+ and the second level describes up to 3 ethernet nodes within
+ that block. The reason for the multiple levels is that the
+ registers for the node are interleaved within a single set
+ of registers. The "ethernet-block" level describes the
+ shared register set, and the "ethernet" nodes describe ethernet
+ port-specific properties.

+SPI (Serial Peripheral Interface) busses
+
+SPI busses can be described with a node for the SPI master device
+and a set of child nodes for each SPI slave on the bus. For this
+discussion, it is assumed that the system's SPI controller is in
+SPI master mode. This binding does not describe SPI controllers
+in slave mode.
+
+The SPI master node requires the following properties:
+- #address-cells - number of cells required to define a chip select
+ address on the SPI bus.
+- #size-cells - should be zero.
+- compatible - name of SPI bus controller following generic names
+ recommended practice.
+No other properties are required in the SPI bus node. It is assumed
+that a driver for an SPI bus device will understand that it is an SPI bus.
+However, the binding does not attempt to define the specific method for
+assigning chip select numbers. Since SPI chip select configuration is
+flexible and non-standardized, it is left out of this binding with the
+assumption that board specific platform code will be used to manage
+chip selects. Individual drivers can define additional properties to
+support describing the chip select layout.
+
+SPI slave nodes must be children of the SPI master node and can
+contain the following properties.
+- reg - (required) chip select address of device.
+- compatible - (required) name of SPI device following generic names
+ recommended practice
+- spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
+- spi-cpol - (optional) Empty property indicating device requires
+ inverse clock polarity (CPOL) mode
+- spi-cpha - (optional) Empty property indicating device requires
+ shifted clock phase (CPHA) mode
+- spi-cs-high - (optional) Empty property indicating device requires
+ chip select active high

+ d) Xilinx IP cores
+
+ The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
+ in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
+ of standard device types (network, serial, etc.) and miscellaneous
+ devices (gpio, LCD, spi, etc). Also, since these devices are
+ implemented within the fpga fabric every instance of the device can be
+ synthesised with different options that change the behaviour.
+
+ Each IP-core has a set of parameters which the FPGA designer can use to
+ control how the core is synthesized. Historically, the EDK tool would
+ extract the device parameters relevant to device drivers and copy them
+ into an 'xparameters.h' in the form of #define symbols. This tells the
+ device drivers how the IP cores are configured, but it requres the kernel
+ to be recompiled every time the FPGA bitstream is resynthesized.
+
+ The new approach is to export the parameters into the device tree and
+ generate a new device tree each time the FPGA bitstream changes. The
+ parameters which used to be exported as #defines will now become
+ properties of the device node. In general, device nodes for IP-cores
+ will take the following form:
+
+ (name): (generic-name)@(base-address) {
+ compatible = "xlnx,(ip-core-name)-(HW_VER)"
+ [, (list of compatible devices), ...];
+ reg = <(baseaddr) (size)>;
+ interrupt-parent = <&interrupt-controller-phandle>;
+ interrupts = < ... >;
+ xlnx,(parameter1) = "(string-value)";
+ xlnx,(parameter2) = <(int-value)>;
+ };
+
+ (generic-name): an open firmware-style name that describes the
+ generic class of device. Preferably, this is one word, such
+ as 'serial' or 'ethernet'.
+ (ip-core-name): the name of the ip block (given after the BEGIN
+ directive in system.mhs). Should be in lowercase
+ and all underscores '_' converted to dashes '-'.
+ (name): is derived from the "PARAMETER INSTANCE" value.
+ (parameter#): C_* parameters from system.mhs. The C_ prefix is
+ dropped from the parameter name, the name is converted
+ to lowercase and all underscore '_' characters are
+ converted to dashes '-'.
+ (baseaddr): the baseaddr parameter value (often named C_BASEADDR).
+ (HW_VER): from the HW_VER parameter.
+ (size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
+
+ Typically, the compatible list will include the exact IP core version
+ followed by an older IP core version which implements the same
+ interface or any other device with the same interface.
+
+ 'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
+
+ For example, the following block from system.mhs:
+
+ BEGIN opb_uartlite
+ PARAMETER INSTANCE = opb_uartlite_0
+ PARAMETER HW_VER = 1.00.b
+ PARAMETER C_BAUDRATE = 115200
+ PARAMETER C_DATA_BITS = 8
+ PARAMETER C_ODD_PARITY = 0
+ PARAMETER C_USE_PARITY = 0
+ PARAMETER C_CLK_FREQ = 50000000
+ PARAMETER C_BASEADDR = 0xEC100000
+ PARAMETER C_HIGHADDR = 0xEC10FFFF
+ BUS_INTERFACE SOPB = opb_7
+ PORT OPB_Clk = CLK_50MHz
+ PORT Interrupt = opb_uartlite_0_Interrupt
+ PORT RX = opb_uartlite_0_RX
+ PORT TX = opb_uartlite_0_TX
+ PORT OPB_Rst = sys_bus_reset_0
+ END
+
+ becomes the following device tree node:
+
+ opb_uartlite_0: serial@ec100000 {
+ device_type = "serial";
+ compatible = "xlnx,opb-uartlite-1.00.b";
+ reg = <ec100000 10000>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <1 0>; // got this from the opb_intc parameters
+ current-speed = <d#115200>; // standard serial device prop
+ clock-frequency = <d#50000000>; // standard serial device prop
+ xlnx,data-bits = <8>;
+ xlnx,odd-parity = <0>;
+ xlnx,use-parity = <0>;
+ };
+
+ Some IP cores actually implement 2 or more logical devices. In
+ this case, the device should still describe the whole IP core with
+ a single node and add a child node for each logical device. The
+ ranges property can be used to translate from parent IP-core to the
+ registers of each device. In addition, the parent node should be
+ compatible with the bus type 'xlnx,compound', and should contain
+ #address-cells and #size-cells, as with any other bus. (Note: this
+ makes the assumption that both logical devices have the same bus
+ binding. If this is not true, then separate nodes should be used
+ for each logical device). The 'cell-index' property can be used to
+ enumerate logical devices within an IP core. For example, the
+ following is the system.mhs entry for the dual ps2 controller found
+ on the ml403 reference design.
+
+ BEGIN opb_ps2_dual_ref
+ PARAMETER INSTANCE = opb_ps2_dual_ref_0
+ PARAMETER HW_VER = 1.00.a
+ PARAMETER C_BASEADDR = 0xA9000000
+ PARAMETER C_HIGHADDR = 0xA9001FFF
+ BUS_INTERFACE SOPB = opb_v20_0
+ PORT Sys_Intr1 = ps2_1_intr
+ PORT Sys_Intr2 = ps2_2_intr
+ PORT Clkin1 = ps2_clk_rx_1
+ PORT Clkin2 = ps2_clk_rx_2
+ PORT Clkpd1 = ps2_clk_tx_1
+ PORT Clkpd2 = ps2_clk_tx_2
+ PORT Rx1 = ps2_d_rx_1
+ PORT Rx2 = ps2_d_rx_2
+ PORT Txpd1 = ps2_d_tx_1
+ PORT Txpd2 = ps2_d_tx_2
+ END
+
+ It would result in the following device tree nodes:
+
+ opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "xlnx,compound";
+ ranges = <0 a9000000 2000>;
+ // If this device had extra parameters, then they would
+ // go here.
+ ps2@0 {
+ compatible = "xlnx,opb-ps2-dual-ref-1.00.a";

+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <3 0>;
+ cell-index = <0>;
+ };
+ };
+
+ Also, the system.mhs file defines bus attachments from the processor
+ to the devices. The device tree structure should reflect the bus
+ attachments. Again an example; this system.mhs fragment:
+
+ BEGIN ppc405_virtex4

+
+ Gives this device tree (some properties removed for clarity):

+
+ i) Xilinx ML300 Framebuffer
+
+ Simple framebuffer device from the ML300 reference design (also on the
+ ML403 reference design as well as others).
+
+ Optional properties:
+ - resolution = <xres yres> : pixel resolution of framebuffer. Some
+ implementations use a different resolution.
+ Default is <d#640 d#480>
+ - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
+ Default is <d#1024 d#480>.
+ - rotate-display (empty) : rotate display 180 degrees.
+
+ ii) Xilinx SystemACE
+
+ The Xilinx SystemACE device is used to program FPGAs from an FPGA
+ bitstream stored on a CF card. It can also be used as a generic CF
+ interface device.
+
+ Optional properties:
+ - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
+
+ iii) Xilinx EMAC and Xilinx TEMAC
+
+ Xilinx Ethernet devices. In addition to general xilinx properties
+ listed above, nodes for these devices should include a phy-handle
+ property, and may include other common network device properties
+ like local-mac-address.
+
+ iv) Xilinx Uartlite
+
+ Xilinx uartlite devices are simple fixed speed serial ports.
+
+ Required properties:
+ - current-speed : Baud rate of uartlite
+
+ v) Xilinx hwicap
+
+ Xilinx hwicap devices provide access to the configuration logic
+ of the FPGA through the Internal Configuration Access Port
+ (ICAP). The ICAP enables partial reconfiguration of the FPGA,
+ readback of the configuration information, and some control over
+ 'warm boots' of the FPGA fabric.
+
+ Required properties:
+ - xlnx,family : The family of the FPGA, necessary since the
+ capabilities of the underlying ICAP hardware
+ differ between different families. May be
+ 'virtex2p', 'virtex4', or 'virtex5'.
+
+ vi) Xilinx Uart 16550
+
+ Xilinx UART 16550 devices are very similar to the NS16550 but with
+ different register spacing and an offset from the base address.
+
