What's the single address cell used for?
I think this is required by the regulator bindings.
Other regulators use the same, though they don't typically
mention it in the properties list but only in the examples.
Nope, nothing to do with regulator that I'm aware of and I've not seen
any examples (but I don't tend to review users too often).
Many examples, really. Just picking one.
Documentation/devicetree/bindings/mfd/tps6507x.txt
regulators {
#address-cells = <1>;
#size-cells = <0>;
...
This also uses the reg property for the regulator index
(without explaining it further). Seems to be pretty common.

Mark, what's the preferred scheme for identifying regulators in a
container node?
+ - regulator-name: arbitrary name for regulator
Drop the 'aribtarary'. Either this should be the name of the regulator
on the board, or it shouldn't be necessary.
Not sure if it even needs to be documented here. It is already documented
in Documentation/devicetree/bindings/regulator/regulator.txt.
Document by reference then? It really should be the name of the supply
provided by the regulator, that wording is probably good. Given that
it's a standard regulator property I'd not document it here at all, just
refer to the generic bindings and say any suitable properties there can
be used.
