- - "renesas,du-r8a7791" for R8A7791 (R-Car M2) compatible DU
+* Renesas R-Car Display Unit (DU)
+
+Required Properties:
+
+ - compatible: must be one of the following.
+ - "renesas,du-r8a7779" for R8A7779 (R-Car H1) compatible DU
+ - "renesas,du-r8a7790" for R8A7790 (R-Car H2) compatible DU
- - R8A7790 and R8A7791 use one functional clock per channel and one clock
- per LVDS encoder. The functional clocks must be named "du.x" with "x"
- being the channel numerical index. The LVDS clocks must be named
++ - "renesas,du-r8a7791" for R8A7791 (R-Car M2-W) compatible DU
++ - "renesas,du-r8a7793" for R8A7793 (R-Car M2-N) compatible DU
++ - "renesas,du-r8a7794" for R8A7794 (R-Car E2) compatible DU
+
+ - reg: A list of base address and length of each memory resource, one for
+ each entry in the reg-names property.
+ - reg-names: Name of the memory resources. The DU requires one memory
+ resource for the DU core (named "du") and one memory resource for each
+ LVDS encoder (named "lvds.x" with "x" being the LVDS controller numerical
+ index).
+
+ - interrupt-parent: phandle of the parent interrupt controller.
+ - 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.
- R8A7791 (M2) DPAD LVDS 0 -
++ - R8A779[0134] use one functional clock per channel and one clock per LVDS
++ encoder (if available). The functional clocks must be named "du.x" with
++ "x" being the channel numerical index. The LVDS clocks must be named
+ "lvds.x" with "x" being the LVDS encoder numerical index.
+ - In addition to the functional and encoder 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.
+
+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.
