The DU block on the RZ/V2H(P) SoC is identical to the one found on the
RZ/G2L SoC. However, it only supports the DSI interface, whereas the
RZ/G2L supports both DSI and DPI interfaces.
Due to this difference, a SoC-specific compatible string
'renesas,r9a09g057-du' is added for the RZ/V2H(P) SoC.

Document DU found in RZ/G2UL SoC. The DU block is identical to RZ/G2L
SoC, but has only DPI interface.
While at it, add missing required property port@1 for RZ/G2L and RZ/V2L
SoCs. Currently there is no user for the DPI interface and hence there
won't be any ABI breakage for adding port@1 as required property for
RZ/G2L and RZ/V2L SoCs.

Document DU found in RZ/V2L SoC. The DU block is identical to RZ/G2L
SoC and therefore use RZ/G2L fallback to avoid any driver changes.

The RZ/G2L LCD controller is composed of Frame Compression Processor
(FCPVD), Video Signal Processor (VSPD), and Display Unit (DU).
The DU module supports the following hardware features
− Display Parallel Interface (DPI) and MIPI LINK Video Interface
− Display timing master
− Generates video timings
− Selecting the polarity of output DCLK, HSYNC, VSYNC, and DE
− Supports Progressive
− Input data format (from VSPD): RGB888, RGB666
− Output data format: same as Input data format
− Supporting Full HD (1920 pixels x 1080 lines) for MIPI-DSI Output
− Supporting WXGA (1280 pixels x 800 lines) for Parallel Output
This patch documents the DU module found on RZ/G2L LCDC.
