Right, especially given that if people can't find the documentation for
driver binding changes that's likely to be one of the first compliants.

Someone would need to get the code working first though depending on
what the hardware does that might not be the right thing.  It's fairly
common to have hardware support for grouping multiple physical
regulators together into a single supply in order to provide more
current with all the control being done from one of the regulators.
