FWIW since I commented on this before and accidentally noticed the repost, the binding looks fine to me now. So, this patch, Reviewed-by: Stephen Warren <swarren@nvidia.com>

Applied both patches squashed together, thanks. Please don't split documentation from the code like this where the code is just a single change - it's sensible where the code is a big series but for single patch it's not helpful. Given the subject line I'd be extremely likely to delete this patch unread, Documentation: says "this isn't relevant".

Here we specify all non-standard bindings which can be used when requesting the use of an GPIO controlled regulator from Device Tree.
