The series here adds support for this codec driver: DT bindings and codec driver itself that consists mainly of two parts: soundwire devices and codec part itself. This audio codec can be found on platforms like QCM2290 and on Qualcomm QRB2210 RB1 board. We are working on this together with Srini (srinivas.kandagatla@oss.qualcomm.com or srini@kernel.org) so this is shared here as minimal working driver and more commits on top of this are expected that will add and extend functionality. Currently with this set the playback via line out or headset work. This driver also has a bit limited support for concurrent playback, since line out path is connected to left input channel.
