Subject: [PATCH v3 0/9] support cmdq helper function on mt6779 platform

This patch support more gce helper function on mt6779 platform.

depends on patch: support gce on mt6779 platform

and depends on following applied patches
soc: mediatek: cmdq: add set event function
soc: mediatek: cmdq: export finalize function
soc: mediatek: cmdq: add assign function

Change since v2:
- Keep behavior in drm crtc driver and
separate bug fix code into another patch.

Change since v1:
- Rename cmdq_mbox_shift() to cmdq_get_shift_pa().


Dennis YC Hsieh (9):
soc: mediatek: cmdq: add address shift in jump
soc: mediatek: cmdq: add write_s function
soc: mediatek: cmdq: add write_s_mask function
soc: mediatek: cmdq: add read_s function
soc: mediatek: cmdq: add write_s value function
soc: mediatek: cmdq: add write_s_mask value function
soc: mediatek: cmdq: add jump function
soc: mediatek: cmdq: add clear option in cmdq_pkt_wfe api
drm/mediatek: reduce clear event
