[PATCH v3 0/5] media: qcom: iris: add support for SM8650

[PATCH v3 0/5] media: qcom: iris: add support for SM8650

[Neil Armstrong]

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

Changes in v3:
- Collected review tags
- Removed bulky reset_controller ops
- Removed iris_vpu_power_off_controller split
- Link to v2: https://lore.kernel.org/r/20250305-topic-sm8x50-iris-v10-v2-0-bd65a3fc099e@linaro.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

[PATCH v3 1/5] dt-bindings: media: qcom,sm8550-iris: document SM8650 IRIS accelerator

[Neil Armstrong]

Document the IRIS video decoder and encoder accelerator found in the
SM8650 platform, it requires 2 more reset lines in addition to the
properties required for the SM8550 platform.

[PATCH v3 2/5] media: platform: qcom/iris: add power_off_controller to vpu_ops

[Neil Armstrong]

In order to support the SM8650 iris33 hardware, we need to provide a
specific constoller power off sequences via the vpu_ops callbacks.

Add the callback, and use the current helper for currently supported
platforms.

[PATCH v3 3/5] media: platform: qcom/iris: introduce optional controller_rst_tbl

[Neil Armstrong]

Introduce an optional controller_rst_tbl use to store reset lines
used to reset part of the controller.

This is necessary for the vpu3 support, when the xo reset line
must be asserted separately from the other reset line
on power off operation.

Factor the iris_init_resets() logic to allow requesting
multiple reset tables.

[PATCH v3 4/5] media: platform: qcom/iris: rename iris_vpu3 to iris_vpu3x

[Neil Armstrong]

The vpu33 HW is very close to vpu3, and shares most of the
operations, so rename file to vpu3x since we'll handle all vpu3
variants in it.

[PATCH v3 5/5] media: platform: qcom/iris: add sm8650 support

[Neil Armstrong]

Add support for the SM8650 platform by re-using the SM8550
definitions and using the vpu33 ops.

The SM8650/vpu33 requires more reset lines, but the H.284
decoder capabilities are identical.

I'm not a big fan of splitting the API into begin/middle/end just for the
sake of de-duplication of small part of code. It ends up introducing a lot
of jumps in the code, which makes it harder to follow.
Keeping it as a single flow, even with some duplication, would be more
readable and maintainable.
