Subject: [PATCH 10/25] ASoC: sun8i-codec: Program format before clock inversion
Date: Wed, 30 Sep 2020 21:11:33 -0500 [thread overview]
Message-ID: <20201001021148.15852-11-samuel@sholland.org> (raw)
In-Reply-To: <20201001021148.15852-1-samuel@sholland.org>
The LRCK inversion bit has a different meaning in DSP mode: it selects
between DSP A and DSP B formats. To support this, we need to know if
the selected format is a DSP format. One easy way to do this is to set
the format field before the inversion fields.
