Subject: [PATCH v4 0/2] Add DT support for video clock controller on SM8150

Signed-off-by: Satya Priya Kakitapalli <[email protected]>
---
Changes in v4:
- Correct the Fixes tag in [1/2]
- Link to v3: https://lore.kernel.org/r/[email protected]

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/[email protected]

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/[email protected]
