[PATCH] ASoC: sun4i-i2s: Add offset to RX channel select

From: Marcus Cooper
Date: Mon Jun 03 2019 - 13:47:28 EST


Whilst testing the capture functionality of the i2s on the newer
SoCs it was noticed that the recording was somewhat distorted.
This was due to the offset not being set correctly on the receiver
side.
