Convert the Renesas R-Car DWC HDMI TX text binding to YAML.
Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>
---
Changes since v1:
- Drop the part numbers in comments, only keep the SoC names
- Use unevaluatedProperties instead of additionalProperties
- Only specify maxItems for clocks and clock-names
- Drop reg, interrupts, #address-cells and #size-cells as they're
checked in the base schema
- Use one size and address cell in example
- Rebase on top of OF graph schema, dropped redundant properties
- Fix identation for enum entries

-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,r8a774a1-hdmi" for R8A774A1 (RZ/G2M) compatible HDMI TX
- - "renesas,r8a774b1-hdmi" for R8A774B1 (RZ/G2N) compatible HDMI TX
- - "renesas,r8a774e1-hdmi" for R8A774E1 (RZ/G2H) compatible HDMI TX
- - "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX
- - "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX
- - "renesas,r8a77961-hdmi" for R8A77961 (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 and RZ/G2 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 at fead0000 {
- compatible = "renesas,r8a7795-hdmi", "renesas,rcar-gen3-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 at 0 {
- reg = <0>;
- dw_hdmi0_in: endpoint {
- remote-endpoint = <&du_out_hdmi0>;
- };
- };
- port at 1 {
- reg = <1>;
- rcar_dw_hdmi0_out: endpoint {
- remote-endpoint = <&hdmi0_con>;
- };
- };
- port at 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>;
- };
- };
