Required properties :



 - compatible : should be "phytium,i2c"

 - reg : Offset and length of the register set for the device

 - interrupts : <IRQ> where IRQ is the interrupt number.

 - clock-frequency : desired I2C bus clock frequency in Hz.



Optional properties:



 - interrupt-names: should be "smbus_alert" if SMBus alert

		    interrupt is supported.



Examples :



	i2c0: i2c@28011000 {

		compatible = "phytium,i2c";

		reg = <0x0 0x28011000 0x0 0x1000>;

		interrupts = <GIC_SPI 89 IRQ_TYPE_LEVEL_HIGH>;

		interrupt-names = "smbus_alert";

		clocks = <&sysclk_48mhz>;

	};
