Hi Eugene,

There is a bit of a movement to asking for power supplies being
described in dt bindings from the start. I'm not insisting on it
as it is easy to add later and always backwards compatible.
(if you don't need to describe a regulator from the start, then it
must always be on so a stub regulator will be fine).

Otherwise looks good to me, but dt bindings should always be cc'd to
the devicetree mailing list and maintainers.   See the MAINTAINERS
file for the email addresses.  For a simple binding there is a bit
of latitude for maintainers to take them without an explicit
review (to keep the DT maintainers sane!) but we always like to
give them the opportunity to comment.  As Rob and Mark will confirm
I'm far from always right in my reviews of these!

Thanks,

Jonathan
