Grant, Rob,

Can one of you please take a look at this patch and see if you have any
comments on the binding definition?

Joel,

Ideally the bindings are described before they are used or along with
its usage. In that aspect, this patch is present too far back in the
series. Can you please fix this if you get to posting another version. I
think I gave the same comment on v9 as well.

ti,hwmods should be optional, no? hwmod is not present on DaVinci where
EDMA is also used. If it is not optional then these bindings wont work
there.

Thanks,
