Subject: [PATCH v5 00/10] Add PSR support for eDP

Changes in v2:
  - Use dp bridge to set psr entry/exit instead of dpu_enocder.
  - Don't modify whitespaces.
  - Set self refresh aware from atomic_check.
  - Set self refresh aware only if psr is supported.
  - Provide a stub for msm_dp_display_set_psr.
  - Move dp functions to bridge code.

Changes in v3:
  - Change callback names to reflect atomic interfaces.
  - Move bridge callback change to separate patch as suggested by Dmitry.
  - Remove psr function declaration from msm_drv.h.
  - Set self_refresh_aware flag only if psr is supported.
  - Modify the variable names to simpler form.
  - Define bit fields for PSR settings.
  - Add comments explaining the steps to enter/exit psr.
  - Change DRM_INFO to drm_dbg_db. 

Changes in v4:
  - Move the get crtc functions to drm_atomic.
  - Add atomic functions for DP bridge too.
  - Add ternary operator to choose eDP or DP ops.
  - Return true/false instead of 1/0.
  - mode_valid missing in the eDP bridge ops.
  - Move the functions to get crtc into drm_atomic.c.
  - Fix compilation issues.
  - Remove dpu_assign_crtc and get crtc from drm_enc instead of dpu_enc.
  - Check for crtc state enable while reserving resources.

Changes in v5:
  - Move the mode_valid changes into a different patch.
  - Complete psr_op_comp only when isr is set.
  - Move the DP atomic callback changes to a different patch.
  - Get crtc from drm connector state crtc.
  - Move to separate patch for check for crtc state enable while
reserving resources.

Vinod Polimera (10):
  drm/msm/disp/dpu1: clear dpu_assign_crtc and get crtc from connector
    state instead of dpu_enc
  drm: add helper functions to retrieve old and new crtc
  drm/msm/dp: use atomic callbacks for DP bridge ops
  drm/msm/dp: Add basic PSR support for eDP
  drm/msm/dp: use the eDP bridge ops to validate eDP modes
  drm/bridge: use atomic enable/disable callbacks for panel bridge
  drm/bridge: add psr support for panel bridge callbacks
  drm/msm/disp/dpu1: use atomic enable/disable callbacks for encoder
    functions
  drm/msm/disp/dpu1: add PSR support for eDP interface in dpu driver
  drm/msm/disp/dpu1: check for crtc enable rather than crtc active to
    release shared resources
