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>;
};
