[PATCH v3 0/9] drm/msm/dpu: simplify QoS/CDP programming

[PATCH v3 0/9] drm/msm/dpu: simplify QoS/CDP programming

[Dmitry Baryshkov]

Merge SSPP and WB code programming QoS and CDP. This allows us to drop
intermediate structures and duplicate code.

Changes since v2:
- Moved SSPP_VIG_CSC_10_OP_MODE close to other CSC10 defines (Jeykumar)

Changes since v1:
- Fixed kerneldoc for _dpu_plane_set_qos_ctrl()
- Fixed danger_safe_en programming conditions (Jeykumar)
- Simplified the code surrounding setup_cdp() calls (Jeykumar)

Dmitry Baryshkov (9):
  drm/msm/dpu: fix SSPP register definitions
  drm/msm/dpu: simplify CDP programming
  drm/msm/dpu: fix the condition for (not) applying QoS to CURSOR SSPP
  drm/msm/dpu: rearrange QoS setting code
  drm/msm/dpu: drop DPU_PLANE_QOS_VBLANK_CTRL
  drm/msm/dpu: simplify qos_ctrl handling
  drm/msm/dpu: drop DPU_PLANE_QOS_PANIC_CTRL
  drm/msm/dpu: remove struct dpu_hw_pipe_qos_cfg
  drm/msm/dpu: use common helper for WB and SSPP QoS setup

[PATCH v3 2/9] drm/msm/dpu: simplify CDP programming

[Dmitry Baryshkov]

Get rid of intermediatory configuration structure and defines. Pass the
format and the enablement bit directly to the new helper. The
WB_CDP_CNTL register ignores BIT(2), so we can write it for both SSPP
and WB CDP settings.

[PATCH v3 3/9] drm/msm/dpu: fix the condition for (not) applying QoS to CURSOR SSPP

[Dmitry Baryshkov]

The function dpu_plane_sspp_update_pipe() contains code to skip enabling
the QoS and OT limitis for CURSOR pipes. However all DPU since sdm845
repurpose DMA SSPP for the cursor planes because they lack the real
CURSOR SSPP. Fix the condition to actually check that the plane is
CURSOR or not.

[PATCH v3 6/9] drm/msm/dpu: simplify qos_ctrl handling

[Dmitry Baryshkov]

After removal of DPU_PLANE_QOS_VBLANK_CTRL, several fields of struct
dpu_hw_pipe_qos_cfg are fixed to false/0. Drop them from the structure
(and drop the corresponding code from the functions).

The DPU_PLANE_QOS_VBLANK_AMORTIZE flag is also removed, since it is now
a NOP.

This flag is always passed to _dpu_plane_set_qos_ctrl(), so drop it and
remove corresponding conditions from the mentioned function.
