Hi Will,

It has a dependency on Krzysztof's clock constraint change [1].

[1] https://lore.kernel.org/all/20260505071453.34000-2-krzysztof.kozlowski@oss.qualcomm.com/

Changes in v4:
 - Rebase on Krzysztof's clock constraint change.
 - Link to v3: https://lore.kernel.org/all/20260504080943.825496-1-shengchao.guo@oss.qualcomm.com/

Changes in v3:
 - Improve commit log to expand APSS and drop "compatible with" part
 - Link to v2: https://lore.kernel.org/all/20260427011728.231026-1-shengchao.guo@oss.qualcomm.com/

Changes in v2:
