Thanks for reviewing the v5 patchset. Here is new patchset addressing all the comments from v5
This patchset adds support for Qualcomm SoundWire Master Controller found in most of Qualcomm SoCs and WCD audio codecs.
This driver along with WCD934x codec and WSA881x Class-D Smart Speaker Amplifier drivers is tested on on DragonBoard DB845c based of SDM845 SoC and Lenovo YOGA C630 Laptop based on SDM850.
SoundWire controller on SDM845 is integrated in WCD934x audio codec via SlimBus interface.
Currently this driver is very minimal and only supports PDM.
Most of the code in this driver is rework of Qualcomm downstream drivers used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team.
TODO: Test and add PCM support.
Thanks, srini
