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 drivers/gpu/drm/mediatek/mtk_disp_drv.h | 2 + drivers/gpu/drm/mediatek/mtk_dpi.c | 9 +++ drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 81 ++++++++++++++++++++- drivers/gpu/drm/mediatek/mtk_drm_crtc.h | 5 +- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.c | 29 +++++++- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.h | 8 ++ drivers/gpu/drm/mediatek/mtk_drm_drv.c | 44 ++++++++--- drivers/gpu/drm/mediatek/mtk_drm_drv.h | 15 +++- drivers/gpu/drm/mediatek/mtk_dsi.c | 9 +++ 9 files changed, 188 insertions(+), 14 deletions(-) -- 2.18.0
