I have the following sound resources in /proc/iomem:
80008000-800083ff : 0.00010000:i2s
80008000-800083ff : Sound DMA
80010000-80010fff : 0.00010000:i2s
80010000-80010fff : Sound Control
I'm not sure whether the first mapping should be split, but I don't know
much about how resource mappings work.

The layout id is 36, and it has both line out and headphone, detected as a
Snapper.
