Nope. ABB LDO module is a standalone instance whose register set
happens to be part of a memory range, as I recently got to know, is a
favorite for our hardware designers to put "misc" modules at SoC
integration time - Sigh! I guess I have made more than enough stink
about this internally already :(.
