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