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) Changes in v14: - Set self_refresh_aware for the PSR to kick in.
