Qualcomm WCD9340/WCD9341 Codec is a standalone Hi-Fi audio codec IC, It supports both I2S/I2C and SLIMbus audio interfaces. On slimbus interface it supports two data lanes; 16 Tx ports and 8 Rx ports. It has Five DACs and seven dedicated interpolators, Seven (six audio ADCs, and one VBAT ADC), Multibutton headset control (MBHC), Active noise cancellation, Sidetone paths, MAD (mic activity detection) and codec processing engine. It supports Class-H differential earpiece out and stereo single ended headphones out. This codec also has integrated SoundWire controller.

This patchset adds very basic support for playback and capture via the interpolators and ADC respectively.
