5 - compatible: must be one of the following.
6 - "renesas,du-r8a7743" for R8A7743 (RZ/G1M) compatible DU
7 - "renesas,du-r8a7745" for R8A7745 (RZ/G1E) compatible DU
8 - "renesas,du-r8a7779" for R8A7779 (R-Car H1) compatible DU
9 - "renesas,du-r8a7790" for R8A7790 (R-Car H2) compatible DU
10 - "renesas,du-r8a7791" for R8A7791 (R-Car M2-W) compatible DU
11 - "renesas,du-r8a7792" for R8A7792 (R-Car V2H) compatible DU
12 - "renesas,du-r8a7793" for R8A7793 (R-Car M2-N) compatible DU
13 - "renesas,du-r8a7794" for R8A7794 (R-Car E2) compatible DU
14 - "renesas,du-r8a7795" for R8A7795 (R-Car H3) compatible DU
15 - "renesas,du-r8a7796" for R8A7796 (R-Car M3-W) compatible DU
17 - reg: A list of base address and length of each memory resource, one for
18 each entry in the reg-names property.
19 - reg-names: Name of the memory resources. The DU requires one memory
20 resource for the DU core (named "du") and one memory resource for each
21 LVDS encoder (named "lvds.x" with "x" being the LVDS controller numerical
24 - interrupt-parent: phandle of the parent interrupt controller.
25 - interrupts: Interrupt specifiers for the DU interrupts.
27 - clocks: A list of phandles + clock-specifier pairs, one for each entry in
28 the clock-names property.
29 - clock-names: Name of the clocks. This property is model-dependent.
30 - R8A7779 uses a single functional clock. The clock doesn't need to be
32 - All other DU instances use one functional clock per channel and one
33 clock per LVDS encoder (if available). The functional clocks must be
34 named "du.x" with "x" being the channel numerical index. The LVDS clocks
35 must be named "lvds.x" with "x" being the LVDS encoder numerical index.
36 - In addition to the functional and encoder clocks, all DU versions also
37 support externally supplied pixel clocks. Those clocks are optional.
38 When supplied they must be named "dclkin.x" with "x" being the input
39 clock numerical index.
41 - vsps: A list of phandle and channel index tuples to the VSPs that handle
42 the memory interfaces for the DU channels. The phandle identifies the VSP
43 instance that serves the DU channel, and the channel index identifies the
44 LIF instance in that VSP.
48 The connections to the DU output video ports are modeled using the OF graph
49 bindings specified in Documentation/devicetree/bindings/graph.txt.
51 The following table lists for each supported model the port number
52 corresponding to each DU output.
