+ROCKCHIP HDMI PHY WITH INNO IP BLOCK
+
+Required properties:
+ - compatible : should be one of the listed compatibles:
+ * "rockchip,rk3228-hdmi-phy",
+ * "rockchip,rk3328-hdmi-phy";
+ - reg : Address and length of the hdmi phy control register set
+ - clocks : phandle + clock specifier for the phy clocks
+ - clock-names : string, clock name, must contain "sysclk" for system
+ control and register configuration, "refoclk" for crystal-
+ oscillator reference PLL clock input and "refpclk" for pclk-
+ based refeference PLL clock input.
+ - #clock-cells: should be 0.
+ - clock-output-names : shall be the name for the output clock.
+ - interrupts : phandle + interrupt specified for the hdmiphy interrupt
+ - #phy-cells : must be 0. See ./phy-bindings.txt for details.
+
+Optional properties for rk3328-hdmi-phy:
+ - nvmem-cells = phandle + nvmem specifier for the cpu-version efuse
+ - nvmem-cell-names : "cpu-version" to read the chip version, required
+ for adjustment to some frequency settings
+
+Example:
+ hdmi_phy: hdmi-phy@12030000 {
+ compatible = "rockchip,rk3228-hdmi-phy";
+ reg = <0x12030000 0x10000>;
+ #phy-cells = <0>;
+ clocks = <&cru PCLK_HDMI_PHY>, <&xin24m>, <&cru DCLK_HDMIPHY>;
+ clock-names = "sysclk", "refoclk", "refpclk";
+ #clock-cells = <0>;
+ clock-output-names = "hdmi_phy";
+ status = "disabled";
+ };
+
+Then the PHY can be used in other nodes such as:
+
+ hdmi: hdmi@200a0000 {
+ compatible = "rockchip,rk3228-dw-hdmi";
+ ...
+ phys = <&hdmi_phy>;
+ phy-names = "hdmi";
+ ...
+ };
