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

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.
