ST-Ericsson U300 Device Tree Bindings

For various board the "board" node may contain specific properties

that pertain to this particular board, such as board-specific GPIOs

or board power regulator supplies.

Required root node property:

compatible="stericsson,u300";

Required node: syscon

This contains the system controller.

- compatible: must be "stericsson,u300-syscon".

- reg: the base address and size of the system controller.

Boards with the U300 SoC include:

S365 "Small Board U365":

Required node: s365

This contains the board-specific information.

- compatible: must be "stericsson,s365".

- vana15-supply: the regulator supplying the 1.5V to drive the

  board.

- syscon: a pointer to the syscon node so we can acccess the

  syscon registers to set the board as self-powered.

Example:

/ {

	model = "ST-Ericsson U300";

	compatible = "stericsson,u300";

	#address-cells = <1>;

	#size-cells = <1>;

	s365 {

		compatible = "stericsson,s365";

		vana15-supply = <&ab3100_ldo_d_reg>;

		syscon = <&syscon>;

	};

	syscon: syscon@c0011000 {

		compatible = "stericsson,u300-syscon";

		reg = <0xc0011000 0x1000>;

	};

};

Clock bindings for ST-Ericsson U300 System Controller Clocks

Bindings for the gated system controller clocks:

Required properties:

- compatible: must be "stericsson,u300-syscon-clk"

- #clock-cells: must be <0>

- clock-type: specifies the type of clock:

  0 = slow clock

  1 = fast clock

  2 = rest/remaining clock

- clock-id: specifies the clock in the type range

Optional properties:

- clocks: parent clock(s)

The available clocks per type are as follows:

Type:  ID:   Clock:

-------------------

0      0     Slow peripheral bridge clock

0      1     UART0 clock

0      4     GPIO clock

0      6     RTC clock

0      7     Application timer clock

0      8     Access timer clock

1      0     Fast peripheral bridge clock

1      1     I2C bus 0 clock

1      2     I2C bus 1 clock

1      5     MMC interface peripheral (silicon) clock

1      6     SPI clock

2      3     CPU clock

2      4     DMA controller clock

2      5     External Memory Interface (EMIF) clock

2      6     NAND flask interface clock

2      8     XGAM graphics engine clock

2      9     Shared External Memory Interface (SEMI) clock

2      10    AHB Subsystem Bridge clock

2      12    Interrupt controller clock

Example:

gpio_clk: gpio_clk@13M {

	#clock-cells = <0>;

	compatible = "stericsson,u300-syscon-clk";

	clock-type = <0>; /* Slow */

	clock-id = <4>;

	clocks = <&slow_clk>;

};

gpio: gpio@c0016000 {

	compatible = "stericsson,gpio-coh901";

	(...)

	clocks = <&gpio_clk>;

};

Bindings for the MMC/SD card clock:

Required properties:

- compatible: must be "stericsson,u300-syscon-mclk"

- #clock-cells: must be <0>

Optional properties:

- clocks: parent clock(s)

mmc_mclk: mmc_mclk {

	#clock-cells = <0>;

	compatible = "stericsson,u300-syscon-mclk";

	clocks = <&mmc_pclk>;

};

mmcsd: mmcsd@c0001000 {

	compatible = "arm,pl18x", "arm,primecell";

	clocks = <&mmc_pclk>, <&mmc_mclk>;

	clock-names = "apb_pclk", "mclk";

	(...)

ST-Ericsson COH 901 318 DMA Controller

This is a DMA controller which has begun as a fork of the

ARM PL08x PrimeCell VHDL code.

Required properties:

- compatible: should be "stericsson,coh901318"

- reg: register locations and length

- interrupts: the single DMA IRQ

- #dma-cells: must be set to <1>, as the channels on the

  COH 901 318 are simple and identified by a single number

- dma-channels: the number of DMA channels handled

Example:

dmac: dma-controller@c00020000 {

	compatible = "stericsson,coh901318";

	reg = <0xc0020000 0x1000>;

	interrupt-parent = <&vica>;

	interrupts = <2>;

	#dma-cells = <1>;

	dma-channels = <40>;

};

Consumers example:

uart0: serial@c0013000 {

	compatible = "...";

	(...)

	dmas = <&dmac 17 &dmac 18>;

	dma-names = "tx", "rx";

};

ST-Ericsson COH 901 571/3 GPIO controller

Required properties:

- compatible: Compatible property value should be "stericsson,gpio-coh901"

- reg: Physical base address of the controller and length of memory mapped

  region.

- interrupts: the 0...n interrupts assigned to the different GPIO ports/banks.
