Subject: [PATCH 00/22] Add support for DU and DSI on the Renesas RZ/G3E SoC

Hi All,

This patch series adds support for the 2 Display Units (DUs) and MIPI DSI
interface found on the Renesas RZ/G3E SoC.

RZ/G3E SoC has 2 LCD controller (LCDC0 and LCDC1), both are composed
of Frame Compression Processor (FCPVD), Video Signal Processor (VSPD),
and Display Unit (DU).

LCDC0 is connected to LVDS (single or dual channel) and DSI.
LCDC1 is connected to LVDS (single ch), DSI, and GPIO (Parallel I/F).

This apply on top of [1].

Thanks & Regards,
Tommaso
