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.
|
||||
|
||||

||||
