Document the Qualcomm WCD9370/WCD9375 Audio Codec and the Soundwire devices than can be found on Qualcomm QCM6490 based platforms.
The Qualcomm WCD9370/WCD9375 Audio Codec communicates with the host SoC over 2 Soundwire links to provide: - 3 TX ADC paths with 4 differential AMIC inputs - 6 DMIC inputs that are shared with AMIC input - 4 Microphone BIAS - RX paths with 4 PAs – HPHL/R, EAR and AUX - Stereo Headphone output - MBHC engine for Headset Detection
