Hi,

Dependency / Rabased on top of
==============================
https://lore.kernel.org/all/20241214-dpu-drop-features-v1-0-988f0662cb7e@linaro.org/

Merging
=======
DSI works! With the fixes here and debugging help from Jessica and
Abhinav, the DSI panel works properly.

The display clock controller patch can go separately.

Changes in v5:
=============
- Add ack/rb tags
- New patches:
  #6: clk: qcom: dispcc-sm8750: Fix setting rate byte and pixel clocks
  #14: drm/msm/dsi/phy: Toggle back buffer resync after preparing PLL
  #15: drm/msm/dsi/phy: Define PHY_CMN_CTRL_0 bitfields
  #16: drm/msm/dsi/phy: Fix reading zero as PLL rates when unprepared
  #17: drm/msm/dsi/phy: Fix missing initial VCO rate

- Patch drm/msm/dsi: Add support for SM8750:
  - Only reparent byte and pixel clocks while PLLs is prepared. Setting
    rate works fine with earlier DISP CC patch for enabling their parents
    during rate change.

- Link to v4: https://lore.kernel.org/r/20250311-b4-sm8750-display-v4-0-da6b3e959c76@linaro.org

Changes in v4
=============
- Add ack/rb tags
- Implement Dmitry's feedback (lower-case hex, indentation, pass
  mdss_ver instead of ctl), patches:
  drm/msm/dpu: Implement 10-bit color alpha for v12.0 DPU
  drm/msm/dpu: Implement CTL_PIPE_ACTIVE for v12.0 DPU

- Rebase on latest next
- Drop applied two first patches
- Link to v3: https://lore.kernel.org/r/20250221-b4-sm8750-display-v3-0-3ea95b1630ea@linaro.org

Changes in v3
=============
- Add ack/rb tags
- #5: dt-bindings: display/msm: dp-controller: Add SM8750:
  Extend commit msg

- #7: dt-bindings: display/msm: qcom,sm8750-mdss: Add SM8750:
  - Properly described interconnects
  - Use only one compatible and contains for the sub-blocks (Rob)

- #12: drm/msm/dsi: Add support for SM8750:
  Drop 'struct msm_dsi_config sm8750_dsi_cfg' and use sm8650 one.
- drm/msm/dpu: Implement new v12.0 DPU differences
  Split into several patches
- Link to v2: https://lore.kernel.org/r/20250217-b4-sm8750-display-v2-0-d201dcdda6a4@linaro.org

Changes in v2
=============
- Implement LM crossbar, 10-bit alpha and active layer changes:
  New patch: drm/msm/dpu: Implement new v12.0 DPU differences
- New patch: drm/msm/dpu: Add missing "fetch" name to set_active_pipes()
- Add CDM
- Split some DPU patch pieces into separate patches:
  drm/msm/dpu: Drop useless comments
  drm/msm/dpu: Add LM_7, DSC_[67], PP_[67] and MERGE_3D_5
  drm/msm/dpu: Add handling of LM_6 and LM_7 bits in pending flush mask
- Split DSI and DSI PHY patches
- Mention CLK_OPS_PARENT_ENABLE in DSI commit
- Mention DSI PHY PLL work:
  https://patchwork.freedesktop.org/patch/542000/?series=119177&rev=1
- DPU: Drop SSPP_VIG4 comments
- DPU: Add CDM
- Link to v1: https://lore.kernel.org/r/20250109-b4-sm8750-display-v1-0-b3f15faf4c97@linaro.org

Best regards,
Krzysztof
