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
