Subject: [PATCH 19/22] 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.
