soundwire: Intel: stop sdw clock in system suspend

2026-09-08T13:54:32+00:00

Perform clock stop with proper mode so that the Peripherals can enter the deserved power state. And keep the bus unwakeable because there is no need to wake up the bus in system suspend.

soundwire: Intel: add wake_enable parameter to stop_bus ops

2026-09-08T13:54:32+00:00

Currently, we assume the bus is wakeable when the bus clock stops. But in some case like system suspend, we want to stop the bus but keep the bus unwakeable. No function change in this commit.

soundwire: bus: add CLOCK_STOP_MODE1 support back

2026-09-08T13:54:32+00:00

CLOCK_STOP_MODE1 is used when the Peripheral might have entered a deeper power-saving mode that does not retain state while the Clock is stopped. It is useful when the device is more power consumption sensitive. Add it back to allow the Peripheral use CLOCK_STOP_MODE1.

soundwire: dmi-quirks: Disable ghost Realtek on Lenovo Pro 9

2026-09-08T13:53:28+00:00

The Lenovo Pro 9 also has a Realtek device in the ACPI that doesn't exist in the physical hardware. This confuses the machine driver into attempting to create DAI links for the device. Add a quirk to remove this device. Signed-off-by: Charles Keepax Link: https://patch.msgid.link/20260903102743.3782541-1-ckeepax@opensource.cirrus.com Signed-off-by: Vinod Koul

soundwire: qcom: cache SCP_ADDRPAGE1/2 to preserve MBQ atomicity

2026-09-08T13:52:51+00:00

qcom_swrm_xfer_msg() reprograms SCP_ADDRPAGE1/2 before every paged transfer, even when the paging window hasn't changed. Besides the wasted bus transactions, this breaks the atomicity that SoundWire Classic Multi-Byte Quantity (MBQ) writes rely on: the kernel's MBQ regmap emits an MBQ pair as two sdw_write_no_pm() calls to bit-13 aliases sharing the same page, and the intervening PAGE writes invalidate the MBQ high-byte staging on Peripherals that observe them. On WCD9378 FU42 Q7.8 Channel Volume this drops the MSB byte silently. Per SDCA v1.1 sections 12.2.5 and 12.2.8.2.1, MBQ pairs are expected to be atomic on the wire. Cache the last-programmed page values per Slave, skip the FIFO write when they match, and invalidate on re-attach since SCP_ADDRPAGE1/2 reset to defaults on re-enumeration.

soundwire: cadence_master: wait and cancel cdns->work before clock stop

2026-09-08T13:49:42+00:00

A peripheral event could happen during the clock stop process. We need to wait for the event be handled before stopping the bus clock. Otherwise, we will get the IO transfer timed out issue.

soundwire: bus: iterate DT compatibles for class-ID match

2026-09-08T13:47:10+00:00

sdw_of_find_slaves() reads only the first "compatible" string on a SoundWire slave DT node and rejects the node if that string does not parse as sdwVMMMPPPPXX. This prevents the standard DT convention of placing a vendor-variant compatible ahead of the SoundWire class-ID compatible: compatible = "vendor,partname", "sdwVMMMPPPPXX"; Iterate every string in the compatible property and accept the first one that parses as a SoundWire class ID. The vendor-variant string remains visible to driver probe callbacks via device_is_compatible() for mode/variant disambiguation.
