[PATCH v4 0/4] ASoC: qcom and pinctrl: add LPASS LPR voting and Hawi LPASS LPI TLMM

[Prasad Kumpatla]

This series adds support for LPASS low-power resource (LPR) voting
through PRM and introduces LPASS LPI TLMM pinctrl support for newer
platforms such as Hawi.

On such platforms, LPASS requires LPR resource voting via PRM to keep
the subsystem active. This is handled by adding a new clock ID and
support for PARAM_ID_RSC_CPU_LPR in q6prm.

Additionally, a new LPASS LPI TLMM block is introduced, requiring a
dedicated DT binding and pinctrl driver.

Chanes in v4:
	- Addressed Krzysztof comments, Drop Q6AFE_MAX_CLK_ID from the bindings
	  since it is not used in-tree.
	- Link to v3: https://lore.kernel.org/linux-arm-msm/20260715133243.3170821-1-prasad.kumpatla@xxxxxxxxxxxxxxxx/

Changes in v3:
	- Drop the mutex cleanup patch from this series. Since this change
	  is not required for Hawi enablement, keep the current series 
	  focused on LPASS LPR voting and LPASS LPI TLMM support, and 
	  address the cleanup in a dedicated follow-up series.
	 - As Srini suggested changed LPR_CPU_SS_SLEEP_DISABLED to LPR_CPU_SS_SLEEP_DISABLE in patch#2.
	 - Link to v2: https://lore.kernel.org/all/20260713184549.929569-1-prasad.kumpatla@xxxxxxxxxxxxxxxx/

Changes in v2:
	- Add mutex cleanup devm-managed in LPASS LPI Pinctrl. 
	- Addressed Bart Comments related to newline and readability.
	- Link to v1: https://lore.kernel.org/linux-arm-msm/20260708114924.1069239-1-prasad.kumpatla@xxxxxxxxxxxxxxxx/
