Subject: [PATCH v2 0/7] media: qcom: iris: add support for SM8650

Add support for the IRIS accelerator for the SM8650
platform, which uses the iris33 hardware.

The vpu33 requires a different reset & poweroff sequence
in order to properly get out of runtime suspend.

Based on the downstream implementation at:
- https://git.codelinaro.org/clo/la/platform/vendor/opensource/video-driver/
  branch video-kernel.lnx.4.0.r4-rel

Signed-off-by: Neil Armstrong <neil.armstrong@...aro.org>

Changes in v2:
- Collected bindings review
- Reworked rest handling by adding a secondary optional table to be used by controller poweroff
- Reworked power_off_controller to be reused and extended by vpu33 support
- Removed useless and unneeded vpu33 init
- Moved vpu33 into vpu3x files to reuse code from vpu3
- Moved sm8650 data table into sm8550
- Link to v1: https://lore.kernel.org/r/20250225-topic-sm8x50-iris-v10-v1-0-128ef05d9665@linaro.org
