From 5a50483c47b8cf3066eb151fa21e195f3dfab5a8 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Tue, 16 Apr 2024 09:14:07 +0200 Subject: [PATCH] ASoC: dt-bindings: mt8192: Document audio-routing and dai-link subnode Document the dai-link subnodes and the audio-routing property, allowing to describe machine specific audio hardware and links in device tree. While at it, also deprecate the old properties which were previously used with the driver's partially hardcoded configuration. Also, since describing machine specific audio hardware and links replaces the now deprecated old logic doing the same in a driver hardcoded fashion, it is not allowed to have both the old and new properties together.
