[PATCH 3/4] dt-bindings: arm: mediatek: audsys: Support mt8192-audsys variant

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>
Date: 2026-01-15 12:56:57
Also in: linux-arm-kernel, linux-mediatek, linux-sound, lkml
Subsystem: open firmware and flattened device tree bindings, the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Add support for the mediatek,mt8192-audsys compatible, which uses
a different audio controller (mt8192-afe-pcm) compared to mt8183
and mt2701.

This resolves a dtbs_check warning on all MT8192 devicetrees.
