[PATCH 1/2] ASoC: dt-bindings: fsl,audmix: Add support for i.MX952 platform

From: Shengjiu Wang <hidden>
Date: 2026-01-16 10:17:28
Also in: imx, linux-arm-kernel, linux-devicetree, linux-sound, lkml
Subsystem: open firmware and flattened device tree bindings, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Liam Girdwood, Mark Brown, Linus Torvalds

The specific feature for AUDMIX on i.MX952 is that it can be bypassed,
so add fsl,amix-bypass property for this feature, besides this there is
no power domain defined on i.MX952, so make power-domains to be
dedicated to i.MX8QM.
