CIRRUS LOGIC Fractional-N Clock Synthesizer & Clock Multiplier

Required properties:

- compatible:		"cirrus,cs2000-cp"

- reg:			The chip select number on the I2C bus

- clocks:		common clock binding for CLK_IN, XTI/REF_CLK

- clock-names:		CLK_IN : clk_in, XTI/REF_CLK : ref_clk

- #clock-cells:		must be <0>

Example:

&i2c2 {

	...

	cs2000: clk_multiplier@4f {

		#clock-cells = <0>;

		compatible = "cirrus,cs2000-cp";

		reg = <0x4f>;

		clocks = <&rcar_sound 0>, <&x12_clk>;

		clock-names = "clk_in", "ref_clk";

	};
