-Binding for the Cadence I2C controller
-
-Required properties:
-  - reg: Physical base address and size of the controller's register area.
-  - compatible: Should contain one of:
-		* "cdns,i2c-r1p10"
-		Note:	Use this when cadence i2c controller version 1.0 is used.
-		* "cdns,i2c-r1p14"
-		Note:	Use this when cadence i2c controller version 1.4 is used.
-  - clocks: Input clock specifier. Refer to common clock bindings.
-  - interrupts: Interrupt specifier. Refer to interrupt bindings.
-  - #address-cells: Should be 1.
-  - #size-cells: Should be 0.
-
-Optional properties:
-  - clock-frequency: Desired operating frequency, in Hz, of the bus.
-  - clock-names: Input clock name, should be 'pclk'.
-
-Example:
-	i2c@e0004000 {
-		compatible = "cdns,i2c-r1p10";
-		clocks = <&clkc 38>;
-		interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
-		reg = <0xe0004000 0x1000>;
-		clock-frequency = <400000>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-	};
