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. |
|
