Merge tag 'soundwire-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire
Pull soundwire updates from Vinod Koul:
"Device numbering and intel driver changes are main features:
- Core support for soundwire device number allocation
- intel driver updates for adding hw_params for DAI ops, hybrid
number allocation and power managemnt callback updates
- DT header include changes for subsystem"
* tag 'soundwire-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire:
soundwire: intel_ace2x: add DAI hw_params/prepare/hw_free callbacks
soundwire: intel_auxdevice: add hybrid IDA-based device_number allocation
soundwire: bus: add callbacks for device_number allocation
soundwire: extend parameters of new_peripheral_assigned() callback
soundWire: intel_auxdevice: resume 'sdw-master' on startup and system resume
soundwire: intel_auxdevice: enable pm_runtime earlier on startup
soundwire: Explicitly include correct DT includes
