[PATCH v2 0/3] soundwire: allow for more than 8 devices, keep IDA for wake-capable devices

From: Bard Liao

This series suggests a hybrid strategy for device number allocation, where
only wake-capable devices use a system-unique Device Number which will be
used on LunarLake to handle wake-ups using the HDaudio WAKEEN and WAKESTS.

Pierre-Louis Bossart (3):
soundwire: extend parameters of new_peripheral_assigned() callback
soundwire: bus: add callbacks for device_number allocation
soundwire: intel_auxdevice: add hybrid IDA-based device_number
allocation

v2:
- Move the device numver allocation from bus.c to intel_auxdevice.c
- List the codecs with wake capability in a quirk table, and assign device
number according to that quirk table.
