Subject: [PATCH v2 00/10] drm: Add DSI/DP support for Renesas r8a779h0 V4M
 and grey-hawk board

Add everything needed to support the DSI output on Renesas r8a779h0
(V4M) SoC, and the DP output (via sn65dsi86 DSI to DP bridge) on the
Renesas grey-hawk board.

Overall the DSI and the board design is almost identical to Renesas
r8a779g0 and white-hawk board.

Changes in v2:
- Add the DT binding with a new conditional block, so that we can set
  only the port@0 as required
- Drop port@1 from r8a779h0.dtsi (there's no port@1)
- Add a new patch to write DPTSR only if num_crtcs > 1
- Drop RCAR_DU_FEATURE_NO_DPTSR (not needed anymore)
- Add Cc: stable to the fix, and move it as first patch
- Added the tags from reviews
- Link to v1: https://lore.kernel.org/r/20241203-rcar-gh-dsi-v1-0-738ae1a95d2a@ideasonboard.com
