Subject: [PATCH v3 00/11] Support IGT in display driver

This series is based on mediatek-drm-next.

This series adds support for running IGT (Intel GPU Tool) tests
with MediaTek display driver. The following changes will be
applied:

1. Add a new API for creating GCE thread loop to retrieve CRCs
   from the hardware component
2. Support hardware CRC calculation in both VDOSYS0 and VDOSYS1
3. Support alpha blending in both VDOSYS0 and VDOSYS1

Changes in v3:
- Modify the dt-binding document of Mediatek OVL
- Set DRM mode configs accroding to the hardware capabilities
- Replace cmdq_pkt_jump_absolute() with cmdq_pkt_jump()

Changes in v2:
- Simplify CMDQ by adding commands that are currently used only
- Integrate CRC related codes into new APIs for Mixer and OVL to reuse
- Add CPU version CRC retrieval when CMDQ is disabled

Hsiao Chien Sung (11):
  soc: mediatek: Add register definitions for GCE
  soc: mediatek: Disable 9-bit alpha in ETHDR
  dt-bindings: display: mediatek: ovl: Modify rules for MT8195/MT8188
  drm/mediatek: Add OVL compatible name for MT8195
  drm/mediatek: Set DRM mode configs accordingly
  drm/mediatek: Support alpha blending in display driver
  drm/mediatek: Support alpha blending in VDOSYS0
  drm/mediatek: Support alpha blending in VDOSYS1
  drm/mediatek: Support CRC in display driver
  drm/mediatek: Support CRC in VDOSYS0
  drm/mediatek: Support CRC in VDOSYS1
