Message

To support DSI and eDP as main display connector without modifying
mtk-drm driver, we add connector dynamic selection capability.

Change in v9:
1. change subject title and [PATCH v9 5/7] title.
2. separate [PATCH v8 4/8] to 2 parts and merge them into [PATCH v9 4/7]
   and [PATCH v9 5/7].
3. fix typo and some grammar problems in commit message.

Change in v8:
1. add mtk_drm_crtc_path enum to replace array index of all_drm_priv.
2. separate add encoder_index function to another patch.
3. separate add dpi and dsi encoder_index function implementation to
   another patch.
4. separate add dsi conn_routes support to another patch.
5. set encoder_index to -1 if comp->dev doesn't not exist and add
   (encoder_index >= 0) checking before assigning conn_routes.
6. move conn_routes statement to the end of mtk_drm_crtc_create.

Change in v7:
1. separate 2 fixes patch from v6.
2. remove unnecessary null checking and variable.
3. move ddp_comp checking to crtc create.

Change in v6:
1. remove max_ddp_comp_nr.

Change in v5:
1. Change conn_routes array to single component enum id.

Change in v4:
1. Change variable naming from conn_route_num to num_conn_routes.
2. Change he encoder_index function return valuew from int to unsigned int.

Change in v3:
1. Change max_num comparison statement to max().

Change in v2:
1. rebase on linux-next: next-20230426
2. Fix alphabetical order and max_num condition check problem.

Change in v1:
1. based on mediatek-drm maintainer's tree / mediatek-drm-next branch:
https://git.kernel.org/pub/scm/linux/kernel/git/chunkuang.hu/linux.git/log/?h=mediatek-drm-next

Jason-JH.Lin (7):
  drm/mediatek: Add mmsys_dev_num to mt8188 vdosys0 driver data
  drm/mediatek: Add crtc path enum for all_drm_priv array
  drm/mediatek: Fix using wrong drm private data to bind mediatek-drm
  drm/mediatek: Add encoder_index function to mtk_ddp_comp_funcs for dpi
  drm/mediatek: Add connector dynamic selection capability for mt8188
  drm/mediatek: dsi: Support dynamic connector selection
  drm/mediatek: Support DSI on MT8188 VDOSYS0
