Laurent Pinchart907c1bb2016-12-02 01:02:53 +02001Renesas 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,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. Each port shall have a single endpoint.
29
30Optional properties:
31
32- power-domains: Shall reference the power domain that contains the DWC HDMI,
33 if any.
