Kernel-4.18.0-80.el8_inno_hdmi-rockchip

Rockchip specific extensions to the Innosilicon HDMI

Required properties:

• compatible:
  “rockchip,rk3036-inno-hdmi”;
• reg:
  Physical base address and length of the controller’s registers.
• clocks, clock-names:
  Phandle to hdmi controller clock, name should be “pclk”
• interrupts:
  HDMI interrupt number
• ports:
  Contain one port node with endpoint definitions as defined in
  Documentation/devicetree/bindings/graph.txt.
• pinctrl-0, pinctrl-name:
  Switch the iomux of HPD/CEC pins to HDMI function.

Example:
hdmi: hdmi@20034000 {
compatible = “rockchip,rk3036-inno-hdmi”;
reg = <0x20034000 0x4000>;
interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cru PCLK_HDMI>;
clock-names = “pclk”;
pinctrl-names = “default”;
pinctrl-0 = <&hdmi_ctl>;

hdmi_in: port {
    #address-cells = <1>;
    #size-cells = <0>;
    hdmi_in_lcdc: endpoint@0 {
        reg = <0>;
        remote-endpoint = <&lcdc_out_hdmi>;
    };
};

};
