[alsa-devel] [PATCH 0/6] ASoC: Add support to WCD9340/WCD9341 codec

[Srinivas Kandagatla]

This patchset adds support to Qualcomm WCD9340/WCD9341 Codec which
is a standalone Hi-Fi audio codec IC.
This codec 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,
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.
Patchset for this is already sent for review at
https://lwn.net/Articles/790651/
    
This patchset has been tested on SDM845 based DragonBoard DB845c with WSA881x
smart speaker amplifiers via soundwire and 4 DMICs.

Thanks,
srini
