[RFC PATCH 23/23] arm64: dts: qcom: mahua-t14s: add WSA speaker protection VI feedback
From: Srinivas Kandagatla
Date: Fri Oct 23 2026 - 13:27:00 EST
Add the V/I sense DAIs of the two WSA8845 speakers, the SoundWire VI
ports and the WSA macro VI capture DAI to the WSA Playback link, for
speaker protection. The speakers now expose two DAIs, so give them a
'#sound-dai-cells' of 1 and address the playback DAI explicitly.
