Subject: [RFC PATCH 19/34] ASoC: sun8i-codec: Support mono DAI configurations
Date: Mon, 17 Feb 2020 00:42:35 -0600 [thread overview]
Message-ID: <20200217064250.15516-20-samuel@sholland.org> (raw)
In-Reply-To: <20200217064250.15516-1-samuel@sholland.org>
Calculate the correct clock rate for a mono configuration.
The AIFs have a bit that must be set for mono input/output.
Set the bit when the number of channels is 1.
