Rockchip RK618 Clock and Reset Unit

This binding uses the common clock binding:
Documentation/devicetree/bindings/clock/clock-bindings.txt

Required properties :
- compatible : Should be "rockchip,rk618-cru"
- clocks : Should contain phandle and clock specifiers for the input clock:
  the AP I2S master clock output(mclk) "clkin", and the AP LCDC master
  dclk output(dclk) "lcdc0_dclkp".
- #clock-cells : Should be 1.

Example:

&rk618 {
	CRU: cru {
		compatible = "rockchip,rk618-cru";
		clocks = <&cru SCLK_I2S_8CH_OUT>, <&cru DCLK_VOP>;
		clock-names = "clkin", "lcdc0_dclkp";
		assigned-clocks = <&CRU SCALER_PLLIN_CLK>, <&CRU VIF_PLLIN_CLK>,
				  <&CRU HDMI_CLK>, <&CRU SCALER_CLK>,
				  <&CRU CODEC_CLK>;
		assigned-clock-parents = <&CRU LCDC0_CLK>, <&CRU LCDC0_CLK>,
					 <&CRU VIF0_CLK>, <&CRU SCALER_PLL_CLK>,
					 <&cru SCLK_I2S_8CH_OUT>;
		#clock-cells = <1>;
		status = "okay";
	};
};
