Actions Semiconductor Owl I2C controller
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should be one of the following:
|
|
- "actions,s700-i2c" for S700 SoC
|
|
- "actions,s900-i2c" for S900 SoC
|
|
- reg : Offset and length of the register set for the device.
|
|
- #address-cells : Should be 1.
|
|
- #size-cells : Should be 0.
|
|
- interrupts : A single interrupt specifier.
|
|
- clocks : Phandle of the clock feeding the I2C controller.
|
|
|
|
Optional properties:
|
|
|
|
- clock-frequency : Desired I2C bus clock frequency in Hz. As only Normal and
|
|
Fast modes are supported, possible values are 100000 and
|
|
400000.
|
|
Examples:
|
|
|
|
i2c0: i2c@e0170000 {
|
|
compatible = "actions,s900-i2c";
|
|
reg = <0 0xe0170000 0 0x1000>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&clock CLK_I2C0>;
|
|
clock-frequency = <100000>;
|
|
};
