Subject: [PATCH v13 00/13] 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.
Changes in v6:
- Remove crtc from dpu_encoder_virt struct.
- fix crtc check during vblank toggle crtc.
- Misc changes.
Changes in v7:
- Add fix for underrun issue on kasan build.
Changes in v8:
- Drop the enc spinlock as it won't serve any purpose in
protetcing conn state.(Dmitry/Doug)
Changes in v9:
- Update commit message and fix alignment using spaces.(Marijn)
- Misc changes.(Marijn)
Changes in v10:
- Get crtc cached in dpu_enc during obj init.(Dmitry)
Changes in v11:
- Remove crtc cached in dpu_enc during obj init.
- Update dpu_enc crtc state on crtc enable/disable during self refresh.
Changes in v12:
- Update sc7180 intf mask to get intf timing gen status
based on DPU_INTF_STATUS_SUPPORTED bit.(Dmitry)
- Remove "clear active interface in the datapath cleanup" change
as it is already included.
Changes in v13:
- Move core changes to top of the series.(Dmitry)
- Drop self refresh aware disable change after psr entry.(Dmitry)
Vinod Polimera (13):
drm: add helper functions to retrieve old and new crtc
drm/bridge: use atomic enable/disable callbacks for panel bridge
drm/bridge: add psr support for panel bridge callbacks
drm/msm/disp/dpu: check for crtc enable rather than crtc active to
release shared resources
drm/msm/disp/dpu: get timing engine status from intf status register
drm/msm/disp/dpu: wait for extra vsync till timing engine status is
disabled
drm/msm/disp/dpu: reset the datapath after timing engine disable
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/msm/disp/dpu: use atomic enable/disable callbacks for encoder
functions
drm/msm/disp/dpu: add PSR support for eDP interface in dpu driver
drm/msm/disp/dpu: update dpu_enc crtc state on crtc enable/disable
during self refresh
