[PATCH v4 00/15] Add display support for the MT8365-EVK board

[Alexandre Mergnat <amergnat@baylibre.com>]

The purpose of this series is to add the display support for the mt8365-evk.

This is the list of HWs / IPs support added:
- Connectors (HW):
  - HDMI
  - MIPI DSI (Mobile Industry Processor Interface Display Serial Interface)
- HDMI bridge (it66121)
- DSI pannel (startek,kd070fhfid015)
- SoC display blocks (IP):
  - OVL0 (Overlay)
  - RDMA0 (Data Path Read DMA)
  - Color0
  - CCorr0 (Color Correction)
  - AAL0 (Adaptive Ambient Light)
  - GAMMA0
  - Dither0
  - DSI0 (Display Serial Interface)
  - RDMA1 (Data Path Read DMA)
  - DPI0 (Display Parallel Interface)

The Mediatek DSI, DPI and DRM drivers are also improved.

The series is rebased on top of Angelo's series [1] to
use the OF graphs support.

Regards,
Alex

Changes in v4:
- Rebase to "next-20240523" branch.
- Patch merged, then removed from the series:
  - dt-bindings: display: mediatek: dpi: add power-domains property
  - dt-bindings: pwm: mediatek,pwm-disp: add compatible for mt8365 SoC
  - clk: mediatek: mt8365-mm: fix DPI0 parent
- Remove mediatek,mt8365-dpi compatible from mtk_drm_drv.c because it
  use the mt8192's data. It's a miss.
- Add MT8365 OF graphs support, remove the hardcoded display path and
  rebase on top of Angelo's series [1].
- Link to v3: https://lore.kernel.org/r/20231023-display-support-v3-0-53388f3ed34b@baylibre.com

Changes in v3:
- Drop "drm/mediatek: add mt8365 dpi support" because it's the same
  config as mt8192 SoC
- Drop "dt-bindings: pwm: mediatek,pwm-disp: add power-domains property"
  because an equivalent patch has been merge already.
- Add DPI clock fix in a separate commit.
- Improve DTS(I) readability.
- Link to v2: https://lore.kernel.org/r/20231023-display-support-v2-0-33ce8864b227@baylibre.com

Changes in v2:
- s/binding/compatible/ in commit messages/titles.
- Improve commit messages as Conor suggest.
- pwm-disp: Set power domain property for MT8365. This one is optionnal
  and can be used for other SoC.
- Fix mediatek,dsi.yaml issue.
- Remove the extra clock in the DPI node/driver and fix the dpi clock
  parenting to be consistent with the DPI clock assignement.
- Link to v1: https://lore.kernel.org/r/20231023-display-support-v1-0-5c860ed5c33b@baylibre.com
