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>;

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:

ST-Ericsson U300 apptimer
Required properties:
- compatible : should be "stericsson,u300-apptimer"
- reg : Specifies base physical address and size of the registers.
- interrupts : A list of 4 interrupts; one for each subtimer. These
