Convert the Renesas R-Car DU text binding to YAML.
Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>
---
Changes since v2:
- Drop boilerplate for ports node
- Add description for interrupts peroperty
- Use single quoted strings to avoid double backslashes
Changes since v1:
- Use pattern instead of enum for dclkin
- Update MAINTAINERS

-* Renesas R-Car Display Unit (DU)
-
-Required Properties:
-
- - compatible: must be one of the following.
- - "renesas,du-r8a7742" for R8A7742 (RZ/G1H) compatible DU

- - "renesas,du-r8a7796" for R8A7796 (R-Car M3-W) compatible DU
- - "renesas,du-r8a77961" for R8A77961 (R-Car M3-W+) compatible DU
- - "renesas,du-r8a77965" for R8A77965 (R-Car M3-N) compatible DU

- - "renesas,du-r8a77995" for R8A77995 (R-Car D3) compatible DU
-
- - reg: the memory-mapped I/O registers base address and length
-
- - interrupts: Interrupt specifiers for the DU interrupts.
-
- - clocks: A list of phandles + clock-specifier pairs, one for each entry in
- the clock-names property.
- - clock-names: Name of the clocks. This property is model-dependent.
- - R8A7779 uses a single functional clock. The clock doesn't need to be
- named.
- - All other DU instances use one functional clock per channel The
- functional clocks must be named "du.x" with "x" being the channel
- numerical index.
- - In addition to the functional clocks, all DU versions also support
- externally supplied pixel clocks. Those clocks are optional. When
- supplied they must be named "dclkin.x" with "x" being the input clock
- numerical index.
-
- - renesas,cmms: A list of phandles to the CMM instances present in the SoC,
- one for each available DU channel. The property shall not be specified for
- SoCs that do not provide any CMM (such as V3M and V3H).
-
- - renesas,vsps: A list of phandle and channel index tuples to the VSPs that
- handle the memory interfaces for the DU channels. The phandle identifies the
- VSP instance that serves the DU channel, and the channel index identifies
- the LIF instance in that VSP.
-
-Optional properties:
- - resets: A list of phandle + reset-specifier pairs, one for each entry in
- the reset-names property.
- - reset-names: Names of the resets. This property is model-dependent.
- - All but R8A7779 use one reset for a group of one or more successive
- channels. The resets must be named "du.x" with "x" being the numerical
- index of the lowest channel in the group.
-
-Required nodes:
-
-The connections to the DU output video ports are modeled using the OF graph
-bindings specified in Documentation/devicetree/bindings/graph.txt.
-
-The following table lists for each supported model the port number
-corresponding to each DU output.

- Port0 Port1 Port2 Port3
