slimbus: qcom-ctrl: drop unneeded qcom,apq8064-slim compatible

2022-11-23T18:45:33Z

Bindings require usage of fallback "qcom,slim" compatible, so "qcom,apq8064-slim" is redundant. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Srinivas Kandagatla Link: https://lore.kernel.org/r/20221118065246.6835-7-srinivas.kandagatla@linaro.org Signed-off-by: Greg Kroah-Hartman

slimbus: stream: add checks for invalid unprepare/disable usage

2022-11-23T18:45:33Z

slim_disable_stream() and slim_stream_unprepare() are exported, so add sanity checks preventing unmatched/invalid calls.

slimbus: qcom-ngd-ctrl: add support for 44.1 Khz frequency

2022-11-23T18:45:33Z

Add support for 44.1Khz frequency by dynamically calculating the slimbus parameters instead of statically defining them.

slimbus: stream: handle unsupported bitrates for presence rate

2022-11-23T18:45:32Z

Handle errors of getting presence rate for unsupported stream bitrate, instead of sending -EINVAL in change content message.

slimbus: qcom-ngd-ctrl: drop PM runtime counter on transfer error paths

2022-11-23T18:45:32Z

If transfer in qcom_slim_ngd_xfer_msg_sync() fails, we need to drop the PM runtime usage counter to have it balanced.

slimbus: qcom-ngd-ctrl: check for device runtime PM status during ISR

2022-11-23T18:45:32Z

Slimbus core interrupt is getting fired after suspend. At this point ADSP slimbus hardware is off with gated clocks which is leading to an unclocked access when HLOS slimbus tried to read the interrupt status register in the ISR.
