soundwire: bus_type: Create IRQ mapping before calling driver probe()

2026-08-14T12:53:25+00:00

Call sdw_irq_create_mapping() before calling the peripheral driver probe() so that it is possible to request the IRQ during probe(). Previously creation of the mapping was conditional on the use_domain_irq flag in the driver properties. But these are filled in after probe(), which meant it wasn't possible to request the IRQ during probe(). This was ok for MFD drivers where only children requested the IRQ. But for normal drivers it led to the non-standard behavior of having to defer requesting the IRQ until after probe().

soundwire: dmi-quirks: Disable ghost Realtek on Asus ROG Zephyrus Duo

2026-08-12T12:08:37+00:00

The Asus ROG Zephyrus Duo 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.

soundwire: stream: validate slave port properties

2026-08-06T08:38:00+00:00

sdw_slave_port_config() validates that a port number is within the generic valid range, but does not verify that the Slave exposes the port for the requested stream direction. As a result, an in-range but unsupported port, or a valid port used in the wrong direction, can be accepted. Use sdw_get_slave_dpn_prop() to perform the direction-specific lookup and reject unsupported ports before storing the runtime configuration.

soundwire: honor clock_reg_supported in the clock scaling check

2026-08-06T08:35:54+00:00

sdw_slave_set_frequency() treats class_id and prop.clock_reg_supported as equivalent evidence that a slave implements the bus-clock base and scale registers, but the bank-switch reprogramming path checks class_id alone, so a class-0 slave that declared the registers never gets the next-bank scale written there. The registers are SoundWire 1.2, not SDCA, so a device may well implement them without setting the class field. Extend the helper to honor clock_reg_supported, as discussed with Pierre-Louis in the WCD9378 review. This also makes a link whose peripherals all declare clock_reg_supported eligible for dynamic clock scaling in the generic bandwidth allocation, which is what declaring the registers means. With the helper extended, sdw_slave_set_frequency()'s open-coded test computes the same predicate; call the helper there instead, so future quirks or updates land in one place.

soundwire: qcom: set the bus mclk_freq property

2026-08-06T08:35:54+00:00

sdw_slave_get_scale_index() needs bus->prop.mclk_freq to compute the SCP bus-clock base and scale register values, and fails with "no bus MCLK" when it is unset. The qcom controller never set it, so slave initialization cannot program the clock registers on this bus: it would fail outright for an SDCA-class slave, and a slave driver declaring clock_reg_supported hits the same error. The pending WCD9378 codec driver hand-rolls these writes as a workaround, following its downstream counterpart. Report the controller clock, letting the core derive the same values the hand-rolled writes program: 19.2 MHz base and the scale matching the bus clock (half the double rate).
