That wouldn't work for my use case, on the Optimus Black, where
regulators are used in a non-standard way. The whole point of this to me
is to not have platform-common code to handle MMC regulators, because
the way those are wired to MMC devices is not the same for each
platform, but is instead board-specific.
Is there any objection to making a v5 that takes the SPL context in
account on each of those boards?
Thanks
