Subject: [PATCH v4 0/7] drm/msm/dpu: add support for independent DSI config
Date: Sat, 17 Jul 2021 15:40:09 +0300	[thread overview]
Message-ID: <20210717124016.316020-1-dmitry.baryshkov@linaro.org> (raw)

This patchseries adds support for independent DSI config to DPU1 display
subdriver. Also drop one of msm_kms_funcs callbacks, made unnecessary
now.

Tested on RB5 (dpu, dsi). Previous iteration was tested by Alexey
Minnekhanov.

Changes since v3:
 - Fix missing semicolon in the msm_dsi_is_master_dsi() stub as noted by
   the kernel test robot

Changes since v2:
 - Removed Reviewed-By tags from changed patches (1, 2)
 - Changed more dual DSI mentions in the patch 1
 - Added msm_dsi_is_master_dsi() helper
 - Rewrote dsi encoder setup function again basing on review by Abhinav

Cahanges since v1:
 - Rewrote dsi encoder setup function by separating common code sequence
   and calling it either for the bonded interface or twice for each of
   the DSI hosts.

Changes since RFC:
 - renamed dual DSI to bonded DSI as suggsted by Abhinav
 - added comments to _dpu_kms_initialize_dsi() regarding encoders usage

The following changes since commit e88bbc91849b2bf57683119c339e52916d34433f:
