[PATCH 5.15 119/244] ASoC: tas2770: Allow mono streams

From: Greg Kroah-Hartman
Date: Tue Aug 23 2022 - 06:14:42 EST


From: Martin Povišer <povik+lin@xxxxxxxxxxx>

commit bf54d97a835dfe62d4d29e245e170c63d0089be7 upstream.

The part is a mono speaker amp, but it can do downmix and switch between
left and right channel, so the right channel range is 1 to 2.
