[PATCH v3 2/3] ASoC: dt-bindings: Add sample format conversion

From: Sameer Pujar
Date: Mon Aug 08 2022 - 01:28:00 EST


Presently "convert-channels" and "convert-rate" DT bindings are available
for channel and rate fixups respectively.

Similarly add "convert-sample-format" binding to fixup DAI sample format
as well. This is added to audio-graph-card based bindings.
