+IMG Serial Control Bus (SCB) I2C Controller
+
+Required Properties:
+- compatible: "img,scb-i2c"
+- reg: Physical base address and length of controller registers
+- interrupts: Interrupt number used by the controller
+- clocks : Should contain a clock specifier for each entry in clock-names
+- clock-names : Should contain the following entries:
+ "scb", for the SCB core clock.
+ "sys", for the system clock.
+- clock-frequency: The I2C bus frequency in Hz
+- #address-cells: Should be <1>
+- #size-cells: Should be <0>
+
+Example:
+
+i2c@18100000 {
+ compatible = "img,scb-i2c";
+ reg = <0x18100000 0x200>;
+ interrupts = <GIC_SHARED 2 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&i2c0_clk>, <&system_clk>;
+ clock-names = "scb", "sys";
+ clock-frequency = <400000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+};
