Subject: [PATCH 16/25] ASoC: sun8i-codec: Enforce symmetric DAI parameters
Date: Wed, 30 Sep 2020 21:11:39 -0500 [thread overview]
Message-ID: <20201001021148.15852-17-samuel@sholland.org> (raw)
In-Reply-To: <20201001021148.15852-1-samuel@sholland.org>
The AIFs have a single register controlling DAI parameters in both
directions, including BCLK/LRCK divisor 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.
