Kernel-4.18.0-80.el8_renesas,dw-hdmi

Renesas Gen3 DWC HDMI TX Encoder

The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
with a companion PHY IP.

These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
following device-specific properties.

Required properties:

  • compatible : Shall contain one or more of

    • “renesas,r8a7795-hdmi” for R8A7795 (R-Car H3) compatible HDMI TX

    • “renesas,r8a7796-hdmi” for R8A7796 (R-Car M3-W) compatible HDMI TX

    • “renesas,r8a77965-hdmi” for R8A77965 (R-Car M3-N) compatible HDMI TX

    • “renesas,rcar-gen3-hdmi” for the generic R-Car Gen3 compatible HDMI TX

      When compatible with generic versions, nodes must list the SoC-specific
      version corresponding to the platform first, followed by the
      family-specific version.

  • reg: See dw_hdmi.txt.

  • interrupts: HDMI interrupt number

  • clocks: See dw_hdmi.txt.

  • clock-names: Shall contain “iahb” and “isfr” as defined in dw_hdmi.txt.

  • ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0
    corresponding to the video input of the controller and one port numbered 1
    corresponding to its HDMI output, and one port numbered 2 corresponding to
    sound input of the controller. Each port shall have a single endpoint.

Optional properties:

  • power-domains: Shall reference the power domain that contains the DWC HDMI,
    if any.

Example:

hdmi0: hdmi@fead0000 {
    compatible = "renesas,r8a7795-dw-hdmi";
    reg = <0 0xfead0000 0 0x10000>;
    interrupts = <0 389 IRQ_TYPE_LEVEL_HIGH>;
    clocks = <&cpg CPG_CORE R8A7795_CLK_S0D4>, <&cpg CPG_MOD 729>;
    clock-names = "iahb", "isfr";
    power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;

    ports {
        #address-cells = <1>;
        #size-cells = <0>;
        port@0 {
            reg = <0>;
            dw_hdmi0_in: endpoint {
                remote-endpoint = <&du_out_hdmi0>;
            };
        };
        port@1 {
            reg = <1>;
            rcar_dw_hdmi0_out: endpoint {
                remote-endpoint = <&hdmi0_con>;
            };
        };
        port@2 {
            reg = <2>;
            rcar_dw_hdmi0_sound_in: endpoint {
                remote-endpoint = <&hdmi_sound_out>;
            };
        };
    };
};

hdmi0-out {
    compatible = "hdmi-connector";
    label = "HDMI0 OUT";
    type = "a";

    port {
        hdmi0_con: endpoint {
            remote-endpoint = <&rcar_dw_hdmi0_out>;
