[PATCH 0/9] Add support for RZ/G2UL DU IP

[PATCH 0/9] Add support for RZ/G2UL DU IP

[Biju Das]

This patch series aims to add support for RZ/G2UL DU.

The LCD controller is composed of Frame Compression Processor (FCPVD),
Video Signal Processor (VSPD), and Display Unit (DU).

The output of LCDC is connected display parallel interface (DPI) and
supports a maximum resolution of WXGA along with 2 RPFs to support the
blending of two picture layers and raster operations (ROPs)

It is similar to LCDC IP on RZ/G2L SoCs, but does not have DSI interface.

[PATCH 1/9] media: dt-bindings: media: renesas,vsp1: Document RZ/G2UL VSPD bindings

[Biju Das]

Document VSPD found in RZ/G2UL SoC. The VSPD block is identical to RZ/G2L
SoC and therefore use RZ/G2L fallback to avoid any driver changes.
