This patch has been tested on support to Qualcomm Robotics RB5 Development Kit based on QRB5165 Robotics SoC. This board has 2 WSA881X smart speakers with onboard DMIC connected to internal LPASS codec via WSA and VA macros respectively. Most of the work is derived from downstream Qualcomm kernels. Credits to various Qualcomm authors from Patrick Lai's team who have contributed to this code. Am guessing existing qcom folder should cover maintining this driver too! If not I can send additional patch to consolidate this along with other Audio related drivers in Maintainer file! Changes since v3: - updated bindings as per Rob's review!
