Subject: [PATCH v5 02/15] ASoC: sun4i-i2s: Add set_tdm_slot functionality
Date: Wed, 14 Aug 2019 08:08:41 +0200 [thread overview]
Message-ID: <20190814060854.26345-3-codekipper@gmail.com> (raw)
In-Reply-To: <20190814060854.26345-1-codekipper@gmail.com>
From: Marcus Cooper <codekipper@gmail.com>
Codecs without a control connection 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 tdm slot bindings to
provide this mechanism.
