[PATCH v3 1/7] ASoC: dt-bindings: sun8i-codec: Increase #sound-dai-cells

From: Samuel Holland
Date: Thu Apr 29 2021 - 23:59:12 EST


Increase sound-dai-cells to 1 to allow using the DAIs in the codec
corresponding to AIF2 and AIF3.

The generic ASoC OF code supports a #sound-dai-cells value of 0 or 1
with no impact to the driver, so this is a backward-compatible change.
