[PATCH v6 3/3] ASoC: sun4i-i2s: Adjust LRCLK width

From: <hidden>
Date: 2019-08-26 18:07:52
Also in: alsa-devel, lkml
Subsystem: sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Linus Torvalds

From: Marcus Cooper <redacted>

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.
