Subject: [PATCH v3 0/3] media: iris: Add support for SM8750 (VPU v3.5)

Changes in v3:
- Patch #1 dt-bindings: Drop venus-common.yaml, add missing opp-570
  in the example.
- Patch #3:
   - Drop reset_control_bulk_reset() in iris_vpu35_power_on_controller()
     (Dikshita)
   - Implement write-retry loop for WRAPPER_IRIS_CPU_NOC_LPI_CONTROL,
     similarly what is done for VPU v3.3
- Link to v2: https://lore.kernel.org/r/20250804-sm8750-iris-v2-0-6d78407f8078@linaro.org

Changes in v2:
- Unify power-off sequence with SM8650 and re-use existing callbacks.
- Drop incorrect WRAPPER_CORE_POWER_CONTROL and unused
  controller_resets.
- Rename FW to qcom/vpu/vpu35_p4.mbn.
- DT binding: correct typo + Rb tag.
- Link to v1: https://lore.kernel.org/r/20250714-sm8750-iris-v1-0-3006293a5bc7@linaro.org

DTS for reference was posted here:
https://lore.kernel.org/all/20250806-b4-sm8750-iris-dts-v2-0-2ce197525eed@linaro.org/

Description:
============
Add support for SM8750 Iris codec with major differences against
previous generation SM8650.

DTS will follow up separately (depends on other DTS patches so cannot be
merged as is).

Tested decoding with Gstreamer (v4l2h264dec).
