[PATCH 15/22] dt-bindings: display: renesas: Add R-Car Gen3 HDMI TX DT bindings

[Laurent Pinchart]

The Renesas R-Car Gen3 SoCs use a Synopsys DWC HDMI TX encoder IP. Add
corresponding device tree bindings based on the DWC HDMI TX bindings
model.

+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,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. 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: hdmi0@fead {
+   compatible = "renesas,r8a7795-dw-hdmi";
+   reg = <0 0xfead 0 0x1>;
+   interrupts = <0 389 IRQ_TYPE_LEVEL_HIGH>;
+   clocks = < CPG_CORE R8A7795_CLK_S0D4>, < CPG_MOD 729>;
+   clock-names = "iahb", "isfr";
+   power-domains = < R8A7795_PD_ALWAYS_ON>;
+   status = "disabled";
+
+   ports {
+   #address-cells = <1>;
+   #size-cells = <0>;
+   port@0 {
+   reg = <0>;
+   dw_hdmi0_in: endpoint {
+   remote-endpoint = <_out_hdmi0>;
+   };
+   };
+   port@1 {
+   reg = <1>;
+   rcar_dw_hdmi0_out: endpoint {
+   remote-endpoint = <_con>;
+   };
+   };
+   };
+   };
+
+   hdmi0-out {
+   compatible = "hdmi-connector";
+   label = "HDMI0 OUT";
+   type = "a";
+
+   port {
+   hdmi0_con: endpoint {
+   remote-endpoint = <_dw_hdmi0_out>;
+   };
+   };
+   };
