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,

Many thanks for reviewing v1.
Changes since v1:
- updated PA gain to a proper TLV control
- move various if else checks to switch case.
- return error on check failure rather than fallback to default
- cleaned up micbias pull up control
- fixed all the gain tlvs correctly
- update dt-bindings to use microvolt for button thresholds
- removed unnecessary debug at various places.
