This series adds support for the Qualcomm Shikra audio platform and
extends VA macro functionality to support SoundWire microphone inputs.
The first part of the series introduces new DT bindings and driver
updates required for LPASS codec version 4.1 used on Shikra, including
RX and VA macro support, version detection enhancements, and associated
register programming changes.
The final patch adds support for routing VA decimators from SoundWire
microphone (SMIC) inputs in addition to existing DMIC sources, allowing
audio capture through SoundWire-connected microphones.
