[PATCH v4] ASoC: kirkwood: add S/PDIF support
Jean-Francois Moine

Mon Oct 21 06:24:22 EDT 2013
This patch adds S/PDIF input/output for mvebu DT boards.
Three output DAI's are created: I2S only, S/PDIF only, both I2S and
S/PDIF.
Signed-off-by: Jean-Francois Moine <moinejf at free.fr>

v4: declare 3 DAI's
v3: (Mark Brown)
- giving a name to the DAI's impacts the Openrd and HP t5325 clients
- test i2s or spdif from the DAI's ID instead of its name
v2: declare 2 DAI's (Mark Brown)
