[PATCH 0/7] ASoC: codecs: add wcd938x support

This patchset adds support for Qualcomm WCD938X codec.

Qualcomm WCD9380/WCD9385 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire devices, RX and
TX respectively supporting 4 x ADCs, ClassH, Ear, Aux PA, 2xHPH,
7 x TX diff inputs, 8 DMICs and MBHC.

Even though this device has two SoundWire devices, only tx device has
access to main codec Control/Status Registers!

This patchset along with other SoundWire patches on the list
have been tested on SM8250 MTP device.

Am planning to send support for MBHC once this driver gets accepted!

Thanks,
srini
