[PATCH v3 0/2] Add DT support for video clock controller on SM8150

[Satya Priya Kakitapalli]

Changes in v3:
- Adding the required-opps property back, which was removed in v2.
- This is needed because the lowest power state for MMCX on sm8150 platform
  is retention, but we want to enable the power domain in low_svs not retention.
- Link to v2: https://lore.kernel.org/r/20240401-videocc-sm8150-dt-node-v2-0-3b87cd2add96@quicinc.com

Changes in v2:
- As per Dmitry's comments, there is no need to update to index based
  lookup for already existing drivers, hence keeping clock-names property.
- Updated the videocc bindings to add AHB clock for the sm8150 platform.
- Link to v1: https://lore.kernel.org/r/20240313-videocc-sm8150-dt-node-v1-0-ae8ec3c822c2@quicinc.com

[PATCH v3 1/2] dt-bindings: clock: qcom: Add AHB clock for SM8150

[Satya Priya Kakitapalli]

SM8150 videocc needs AHB clock, so update the bindings for sm8150
to add the AHB clock.

The tag is incorrect. The mentioned commit didn't add sm8150 bindings,
so it didn't have a bug.

Could you please extend the sm8250 case instead of defining a new one?
Also could you please check if there is a clock (like ahb_clk_src)
that uses bi_tcxo_ao instead of bi_tcxo? If so, we have to add this
clock to the bindings even if the driver doesn't use/model it at this
point.

Thanks, will correct the tag.

There are no clocks using the bi_tcxo_ao on sm8150. Hence added separate 
case for sm8150 instead of re-using sm8250.
