+Actions Semiconductor Owl I2C controller
+
+Required properties:
+
+- compatible : Should be "actions,s900-i2c".
+- 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>;
+ };
