soundwire: qcom: add support for SoundWire controller (02efb49a) · Commits · 戴 / test

Qualcomm SoundWire Master controller is present in most Qualcomm SoCs either integrated as part of WCD audio codecs via slimbus or as part of SOC I/O. This patchset adds support to a very basic controller which has been tested with WCD934x SoundWire controller connected to WSA881x smart speaker amplifiers. Signed-off-by:
