Subject: [PATCH v1] dt-bindings: display: convert rockchip rk3066 hdmi bindings to yaml

Current dts files with 'hdmi' nodes for rk3066 are manually verified.
In order to automate this process rockchip,rk3066-hdmi.txt
has to be converted to yaml.

-Rockchip specific extensions for rk3066 HDMI
-============================================
-
-Required properties:
-- compatible:
- "rockchip,rk3066-hdmi";
-- reg:
- Physical base address and length of the controller's registers.
-- clocks, clock-names:
- Phandle to HDMI controller clock, name should be "hclk".
-- interrupts:
- HDMI interrupt number.
-- power-domains:
- Phandle to the RK3066_PD_VIO power domain.
-- rockchip,grf:
- This soc uses GRF regs to switch the HDMI TX input between vop0 and vop1.
-- ports:
- Contains one port node with two endpoints, numbered 0 and 1,
- connected respectively to vop0 and vop1.
- Contains one port node with one endpoint
- connected to a hdmi-connector node.
-- pinctrl-0, pinctrl-name:
- Switch the iomux for the HPD/I2C pins to HDMI function.
-
-Example:
- hdmi: hdmi@10116000 {
- compatible = "rockchip,rk3066-hdmi";
- reg = <0x10116000 0x2000>;
- interrupts = <GIC_SPI 64 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cru HCLK_HDMI>;
- clock-names = "hclk";
- power-domains = <&power RK3066_PD_VIO>;
- rockchip,grf = <&grf>;
- pinctrl-names = "default";
- pinctrl-0 = <&hdmii2c_xfer>, <&hdmi_hpd>;
