Those 6 properties are custom to this binding so should have a vendor
prefix, e.g. "samsung,supports-6ch".
Okay. I will change this.
Also, I wonder if this shouldn't wait for the forthcoming standardized
DT DMA bindings (or perhaps document custom bindings that are identical
to the new standardized bindings)? Otherwise, the DMA stuff will all
have to be redefined again. Apparently it's hoped the bindings will be
in 3.7, or if not there, in 3.8.
Okay. Once the generic DT DMA bindings are available I will use that.
But It will be good if atleast other things get reviewed.

Thanks
Padma
