[PATCH v2 0/7] drm/msm/dpu: cleanup dpu encoder code

[Dmitry Baryshkov]

This patchset targets DPU encoder code, removing unused artifacts (empty
callbacks, MSM bus client id, etc).

Changes since v2:
 - Expand commit message of 7th patch (pull connector from
   dpu_encoder_phys to dpu_encoder_virt)
 - Drop intf_type patch for now, as it causes controversy

Changes since v1:
 - Split dp audio fixup from the intf_type patch
 - Remove atomic_check() removal, used by the posted WB support

Dmitry Baryshkov (7):
  drm/msm/dpu: fix dp audio condition
  drm/msm: move struct msm_display_info to dpu driver
  drm/msm/dpu: remove msm_dp cached in dpu_encoder_virt
  drm/msm/dpu: drop bus_scaling_client field
  drm/msm/dpu: encoder: drop unused mode_fixup callback
  drm/msm/dpu: switch dpu_encoder to use atomic_mode_set
  drm/msm/dpu: pull connector from dpu_encoder_phys to dpu_encoder_virt

[PATCH v2 1/7] drm/msm/dpu: fix dp audio condition

[Dmitry Baryshkov]

DP audio enablement code which is comparing intf_type,
DRM_MODE_ENCODER_TMDS (= 2) with DRM_MODE_CONNECTOR_DisplayPort (= 10).
Which would never succeed. Fix it to check for DRM_MODE_ENCODER_TMDS.

[PATCH v2 7/7] drm/msm/dpu: pull connector from dpu_encoder_phys to dpu_encoder_virt

[Dmitry Baryshkov]

All physical encoders used by virtual encoder share the same connector,
so pull the connector field from dpu_encoder_phys into dpu_encoder_virt
structure. Otherwise code suggests that different phys_encs
can have different connectors.
