Subject: [PATCH] dt-bindings: phy: rk3228-hdmi-phy: convert to yaml
Convert the binding to yaml and rename it according to its first
compatible instead of the unspecific rockchip-inno-hdmi naming.

-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@...30000 {
- 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@...a0000 {
- compatible = "rockchip,rk3228-dw-hdmi";
- ...
- phys = <&hdmi_phy>;
- phy-names = "hdmi";
- ...
- };
