Subject: [PATCH 4/4] ASoC: simple-card: add DT documentation for multi-DAI links
Date: Fri, 21 Feb 2014 12:43:17 +0100	[thread overview]
Message-ID: <c8340c624ab7ec38700523ce4c70b54db92d21e9.1392995566.git.moinejf@free.fr> (raw)
In-Reply-To: <cover.1392995566.git.moinejf@free.fr>

There may be many couples of CPU/CODEC DAI links.
The example 2 is extracted from the Cubox DT.
