[PATCH v7 00/13] drm: renesas: rz-du: Add RZ/G3E support

[Tommaso Merciai <tommaso.merciai.xr@bp.renesas.com>]

Dear All,

This patch series adds DU/DRM support for the 2 Display Units (DUs) 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,

v6->v7:
 - Rebased on top of next-20260605
 - Splitted the original series into smaller chunks for easy review and easy
   merging. The original series is available here:
   http://lore.kernel.org/all/cover.1775636898.git.tommaso.merciai.xr@bp.renesas.com/
 - PATCH 01/13: Collected LPinchart tag. Removed wrong fixes tag.
 - PATCH 02/13: Rebased on top of [1]. Use single DRM device aggregating
   both DU instances (1 DU dt node), modelling single port for each DU0,
   DU1 and multiple endpoints for outputs.
 - PATCH 12/13: Removed feature flag usage, rebased on top of T2H/N2H LCDC series [1]
   Reworked commit body as now outputs routing is based on endpoint id
   instead of port number. Fixed rzg2l_du_r9a09g047_info instead of
   rzg2l_du_r9a09g047_du_info.
   Added bump of RZG2L_DU_MAX_CRTCS and RZG2L_DU_MAX_VSPS to 2.
