Required properties:
- compatible : Should be "rockchip,rk3036-codec".
- reg : The registers of codec.
- clock-names : Should be "acodec_pclk".
- clocks : The clock of codec.
- rockchip,grf : The phandle of grf device node.

Example:

	acodec: acodec-ana@20030000 {
		compatible = "rk3036-codec";
		reg = <0x20030000 0x4000>;
		rockchip,grf = <&grf>;
		clock-names = "acodec_pclk";
		clocks = <&cru ACLK_VCODEC>;
	};
