Subject: [PATCH v6 3/3] ASoC: sun4i-i2s: Adjust LRCLK width
Date: Mon, 26 Aug 2019 20:07:34 +0200 [thread overview]
Message-ID: <20190826180734.15801-4-codekipper@gmail.com> (raw)
In-Reply-To: <20190826180734.15801-1-codekipper@gmail.com>
From: Marcus Cooper <codekipper@gmail.com>
Some codecs such as i2s based HDMI audio and the Pine64 DAC require
a different amount of bit clocks per frame than what is calculated
by the sample width. Use the values obtained by the tdm slot bindings
to adjust the LRCLK width accordingly.
