1Renesas Gen3 DWC HDMI TX Encoder
 2================================
 3
 4The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
 5with a companion PHY IP.
 6
 7These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
 8Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
 9following device-specific properties.
10
11
12Required properties:
13
14- compatible : Shall contain one or more of
15  - "renesas,r8a774a1-hdmi" for R8A774A1 (RZ/G2M) compatible HDMI TX
16  - "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX
17  - "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX
18  - "renesas,r8a77965-hdmi" for R8A77965 (R-Car M3-N) compatible HDMI TX
19  - "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 and RZ/G2 compatible
20			     HDMI TX
21
22    When compatible with generic versions, nodes must list the SoC-specific
23    version corresponding to the platform first, followed by the
24    family-specific version.
25
26- reg: See dw_hdmi.txt.
27- interrupts: HDMI interrupt number
28- clocks: See dw_hdmi.txt.
29- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
30- ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0
31  corresponding to the video input of the controller and one port numbered 1
32  corresponding to its HDMI output, and one port numbered 2 corresponding to
33  sound input of the controller. Each port shall have a single endpoint.
34
35Optional properties:
36
37- power-domains: Shall reference the power domain that contains the DWC HDMI,
38  if any.
