Subject: [PATCH 1/8] ASoC: spdif: Add S32_LE support for S/PDIF dummy codec drivers
Date: Wed, 22 Nov 2017 20:43:14 +0900	[thread overview]
Message-ID: <20171122114321.29196-2-suzuki.katsuhiro@socionext.com> (raw)
In-Reply-To: <20171122114321.29196-1-suzuki.katsuhiro@socionext.com>

AIO on UniPhier can output S/PDIF where no codec is needed.
This patch adds S32_LE support for dummy codec drivers.

If one S/PDIF controller has its own limitation, its CPU DAI driver should
set the supported format by its own circumstance, since the soc-pcm driver
will use the intersection of cpu_dai's formats and codec_dai's formats.
