I don't quite know how clear that is; the framework is still
sorting itself out, a bit. The 2.6.30 kernel has some updates
to programming interfaces, few of which should matter to any
sensor code ... sensors would be "consumers" in that framework,
calling regulator_get() and friends.
The tricksy bits would be coupling the regulators to the
sensor device nodes in the board-specfiic setup code. At
some point I expect to see some cases where that setup needs
framework updates, but so far that hasn't happened.
