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

-    - "renesas,du-r8a77990" for R8A77990 (R-Car E3) 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
