Unfortunately this change causes a regression on systems with MC13xxx
regulators. The desc.name field is filled with an uppercase name of the
regulator, while the existing DTs (as far as I know) all use lowercase
node names, so the matching in the function above doesn't work anymore.
Any opinions about how to proceed here?
