Subject: [PATCH 0/5] Migrate soc, drm-mediatek, mdp3 to new CMDQ APIs (series 2/4)

From: Jason-jh Lin <jason-jh.lin@...iatek.corp-partner.google.com>

This series migrates the MediaTek SoC, DRM, and MDP3 drivers to the new
CMDQ APIs introduced for MT8196.

Series application order:
  1. [Fixes] Refine DMA address handling for the command buffer
  - https://lore.kernel.org/all/20251022171847.379470-1-jason-jh.lin@mediatek.com/
  2. [Series 1/4] Add GCE support for MT8196 and update CMDQ APIs
  - https://lore.kernel.org/all/20251031155838.1650833-1-jason-jh.lin@mediatek.com/
  3. [Series 2/4] Migrate subsystems to new CMDQ APIs (this series)
  4. [Series 3/4] Remove shift_pa from CMDQ jump functions
  5. [Series 4/4] Remove deprecated CMDQ APIs

Please apply this series after the MT8196 GCE support series,
and before the following series.
