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@oss.qualcomm.com/ 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@oss.qualcomm.com/ 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@oss.qualcomm.com/ Prasad Kumpatla (4): ASoC: dt-bindings: qcom: add LPASS LPR vote clock ID ASoC: qcom: q6prm: add support for LPASS LPR resource voting dt-bindings: pinctrl: qcom,hawi-lpass-lpi-pinctrl: Add Hawi LPI pinctrl pinctrl: qcom: hawi-lpass-lpi: add Hawi LPASS LPI TLMM .../pinctrl/qcom,hawi-lpass-lpi-pinctrl.yaml | 109 ++++++++ drivers/pinctrl/qcom/Kconfig | 10 + drivers/pinctrl/qcom/Makefile | 1 + drivers/pinctrl/qcom/pinctrl-hawi-lpass-lpi.c | 244 ++++++++++++++++++ drivers/pinctrl/qcom/pinctrl-lpass-lpi.h | 17 ++ .../sound/qcom,q6dsp-lpass-ports.h | 2 +- sound/soc/qcom/qdsp6/q6dsp-lpass-clocks.c | 2 +- sound/soc/qcom/qdsp6/q6prm-clocks.c | 2 + sound/soc/qcom/qdsp6/q6prm.c | 16 +- sound/soc/qcom/qdsp6/q6prm.h | 1 + 10 files changed, 399 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/pinctrl/qcom,hawi-lpass-lpi-pinctrl.yaml create mode 100644 drivers/pinctrl/qcom/pinctrl-hawi-lpass-lpi.c -- 2.34.1
