- move common module from display folder to common folder,
  such as AAL, COCLOR, CCORR and MUTEX

Change in v10:
- rebase on "drm/mediatek: add support for mediatek SOC MT8192" series
- rebase on "soc: mediatek: mmsys: add mt8192 mmsys support" series
- fix some typo and "mediatek" start with capital in every dt-bindings
- move mutex yaml from dfisplay folder to soc folder
- separate merge additional propoerties to an individual dt-bindings patch

Change in v9:
- separate power and gce properties of mmsys into another dt-binding patch
- rebase on "Separate aal module" series
- keep mtk_ddp_clk_enable/disable in the same place
- change mtk_dsc_start config register to mtk_drm_ddp_write_mask
- remove the 0 setting of merge fifo config function

- remove bypass DSC enum in mtk_ddp_comp_init

Change in v7:
- add dt=binding of mmsys and disp path into this series
- separate th modidfication of alphabetic order, remove unused define and
  rename the define of register offset to individual patch
- add comment for MERGE ultra and preultra setting

Change in v6:
- adjust alphabetic order for mediatek-drm
- move the patch that add mt8195 support for mediatek-drm as
  the lastest patch
- add MERGE define for const varriable 

Change in v5:
- add power-domain property into vdosys0 and vdosys1 dts node.
- add MT8195 prifix and remove unused VDO1 define in mt8195-mmsys.h

Change in v4:
- extract dt-binding patches to another patch series
- squash DSC module into mtk_drm_ddp_comp.c
- add coment and simplify MERGE config function

Change in v3:
- change mmsys and display dt-bindings document from txt to yaml
- add MERGE additional description in display dt-bindings document
- fix mboxes-cells number of vdosys0 node in dts
- drop mutex eof convert define
