Subject: [PATCH 305/351] ASoC: sun8i-codec: Enforce symmetric DAI parameters
|
||
|
|
|
||
|
|
The AIFs have a single register controlling DAI parameters in both
|
||
|
|
directions, including BCLK/LRCK divisor and word size. The DAIs produce
|
||
|
|
only noise or silence if any of these parameters is wrong. Therefore, we
|
||
|
|
need to enforce symmetry for these parameters, so starting a new
|
||
|
|
substream will not break an existing substream.
