1 Renesas Gen3 DWC HDMI TX Encoder
2 ================================
4 The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
5 with a companion PHY IP.
7 These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
8 Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
9 following device-specific properties.
12 Required properties:
14 - compatible : Shall contain one or more of
15   - "renesas,r8a774a1-hdmi" for R8A774A1 (RZ/G2M) compatible HDMI TX
16   - "renesas,r8a774b1-hdmi" for R8A774B1 (RZ/G2N) compatible HDMI TX
17   - "renesas,r8a774e1-hdmi" for R8A774E1 (RZ/G2H) compatible HDMI TX
18   - "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX
19   - "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX
20   - "renesas,r8a77961-hdmi" for R8A77961 (R-Car M3-W+) compatible HDMI TX
21   - "renesas,r8a77965-hdmi" for R8A77965 (R-Car M3-N) compatible HDMI TX
22   - "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 and RZ/G2 compatible
23                              HDMI TX
25     When compatible with generic versions, nodes must list the SoC-specific
26     version corresponding to the platform first, followed by the
27     family-specific version.
29 - reg: See dw_hdmi.txt.
30 - interrupts: HDMI interrupt number
31 - clocks: See dw_hdmi.txt.
32 - clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
33 - ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0
34   corresponding to the video input of the controller and one port numbered 1
35   corresponding to its HDMI output, and one port numbered 2 corresponding to
36   sound input of the controller. Each port shall have a single endpoint.
38 Optional properties:
40 - power-domains: Shall reference the power domain that contains the DWC HDMI,
41   if any.
