Merge remote-tracking branch 'quic/dev/msm-4.14-display' into msm-4.14.c4 



* quic/dev/msm-4.14-display:
  drm/msm: allow sde_atrace to show up on different process
  drm/msm: enable counter trace
  dts: sa8195: fix display can't work in DP_MST mode
  drm/msm/sde: cleanup writeback phys_enc structures during wb disable
  drm/msm/dsi-staging: Add a new bridge DTS property support
  drm/msm/sde: fix unpaired sde trace
  drm/msm/sde: ensure LUTDMA is complete when auto-refresh enable
  drm/msm/dp: add checks to prevent buffer overflows
