[alsa-devel] [PATCH v2 6/7] ARM: mvebu: enable S/PDIF audio in Armada 370 DB Device Tree

[Thomas Petazzoni]

In addition to the analog audio input and output, the Armada 370 DB
also has S/PDIF input and output optical connectors. This commit
improves the Device Tree description of the Armada 370 DB platform to
enable the S/PDIF support.
