[PATCH v3 00/10] Expand SoundWire enumeration helper coverage

From: Charles Keepax

Date: Mon Jun 08 2026 - 06:38:27 EST


The patch series in [1] added a new helper to remove common boiler plate
waiting for a device to enumerate on SoundWire, however, many devices
also wait for enumeration during probe. This series updates things to be
suitable such that we can call the same helper at probe time when the
unattach_request is not valid.

There is one final step outstanding which is to add a core helper
that waits for a device to drop off the bus. This is not include
in this series and should be the last step of this process.

Thanks,
Charles
