[PATCH AUTOSEL 5.15 07/43] ASoC: dt-bindings: Adjust #sound-dai-cells on TI's single-DAI codecs

From: Sasha Levin
Date: Thu May 25 2023 - 14:46:27 EST


From: Martin Povišer <povik+lin@xxxxxxxxxxx>

[ Upstream commit efb2bfd7b3d210c479b9361c176d7426e5eb8663 ]

A bunch of TI's codecs have binding schemas which force #sound-dai-cells
to one despite those codecs only having a single DAI. Allow for bindings
with zero DAI cells and deprecate the former non-zero value.
