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


Hello,
is there still interest in upstreaming this?

We're interested in enabling more comprehensive IGT tests on MediaTek SoCs
and this series is definitely useful.

Regards,
Angelo

Changes in v4:
- Seperate the patch into smaller ones
- Change the title of some patches
- Revert the changes that are not related to the series

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
