From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> Add support for audio on Lenovo T14s laptop, coming with two speakers, audio jack and two digital microphones. This is very early work, not yet complete: 1. 2x speakers: work OK. 2. 2x digital microphones: work OK. 3. Headset (audio jack) recording: does not work. 4. Headphones playback (audio jack): channels are intermixed.

Audioreach topology was already pushed to main branch: https://github.com/linux-msm/audioreach-topology 2. ALSA UCM files are ready and soon will be pushed by Srini.
