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,r8a774a1-hdmi" for R8A774A1 (RZ/G2M) compatible HDMI TX

16
  - "renesas,r8a774b1-hdmi" for R8A774B1 (RZ/G2N) compatible HDMI TX

17
  - "renesas,r8a774e1-hdmi" for R8A774E1 (RZ/G2H) compatible HDMI TX

18
  - "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX

19
  - "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX

20
  - "renesas,r8a77961-hdmi" for R8A77961 (R-Car M3-W+) compatible HDMI TX

21
  - "renesas,r8a77965-hdmi" for R8A77965 (R-Car M3-N) compatible HDMI TX

22
  - "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 and RZ/G2 compatible

23
			     HDMI TX

24


25
    When compatible with generic versions, nodes must list the SoC-specific

26
    version corresponding to the platform first, followed by the

27
    family-specific version.

28


29
- reg: See dw_hdmi.txt.

30
- interrupts: HDMI interrupt number

31
- clocks: See dw_hdmi.txt.

32
- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.

33
- ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0

34
  corresponding to the video input of the controller and one port numbered 1

35
  corresponding to its HDMI output, and one port numbered 2 corresponding to

36
  sound input of the controller. Each port shall have a single endpoint.

37


38
Optional properties:

39


40
- power-domains: Shall reference the power domain that contains the DWC HDMI,

41
  if any.
