Subject: [PATCH 0/4] 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 (4):
  soundwire: add enum to control device number allocation
  soundwire: introduce SDW_DEV_NUM_ALLOC_IDA_WAKE_ONLY
  soundwire: extend parameters of new_peripheral_assigned() callback
  soundwire: intel_auxdevice: use SDW_DEV_NUM_ALLOC_IDA_WAKE_ONLY
