Subject: [PATCH v2 03/20] ASoC: sun4i-i2s: Adjust LRCLK width
Date: Thu, 3 Sep 2020 22:30:17 +0200 [thread overview]
Message-ID: <20200903203034.1057334-4-peron.clem@gmail.com> (raw)
In-Reply-To: <20200903203034.1057334-1-peron.clem@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.
