+Required properties:
+- compatible: should be "sigma,smp8642-i2c"
+- reg: physical address space of the device
+- interrupts: the interrupt of the device
+- clocks: phandle of the clock for the device
+- #address-cells: should be <1>
+- #size-cells: should be <0>
+
+Optional properties:
+- clock-frequency: frequency of bus clock in Hz, default 100kHz
+
+Example:
+
+i2c@10480 {
+ compatible = "sigma,smp8642-i2c";
+ reg = <0x10480 0x2c>;
+ interrupts = <22 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&sys_clk>;
+ clock-frequency = <100000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+};
