[PATCH v2 0/3] ASoC: qcom: lpass: Switch VA/WSA macros to PM clock framework

Posted by Ajay Kumar Nandam 1 month, 3 weeks ago

This series converts LPASS WSA and VA macro codec drivers to the PM
clock framework for runtime PM clock handling.

Clock enable/disable sequencing during runtime suspend/resume is moved
to pm_clk helpers, while regcache state handling remains in the driver
runtime PM callbacks. This aligns these codec drivers with common LPASS
runtime PM patterns and reduces idle clock voting.

Patch 3 switches WSA MCLK clock registration to devm-managed
clk_hw registration.

v1: lore.kernel.org/r/20260413121824.375473-1-ajay.nandam@oss.qualcomm.com

Changes since v1:
- Fixed runtime resume error handling in WSA/VA paths:
  - keep regcache cache-only on pm_clk_resume() failure
  - unwind clocks with pm_clk_suspend() if regcache_sync() fails
- Dropped the separate "Guard optional NPL clock rate programming"
  patch as discussed on list
