Subject: [PATCH 0/3] Allow composer fallbacks for color features

This series will enable color features on sc7280 target which has primary panel as eDP

The series removes dspp allocation based on encoder type and allows the datapath reservation
even if dspps are not available.

The series also adds a check to fail the composition during atomic check , if color management is requested 
and no dspps are allocated in the datapath.

This can allow composer fallbacks for color features if no relevant HW blocks are available.

Kalyan Thota (3):
  drm/msm/disp/dpu1: allow reservation even if dspps are not available.
  drm/msm/disp/dpu1: allow dspp selection for all the interfaces
  drm/msm/disp/dpu1: fail atomic check if color feature is requested
    with no dspp
