Subject: [PATCH] ASoC: tas2770: Allow mono streams
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
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.
