I can see the spdif card getting probed. When I run 'aplay' the spdif
light turns on, but I cannot test it due to the lack of spdif equipment at the
moment.
Changes since v2:
- Remove unneeded blank line
Changes since v1:
- Fix the identation level os spdif node
- Remove unneeded blank lines

Unfortunately I don't have a wandboard to test this.
But it should be fine since I am using same binding on Sabreauto.
