Ah, okay. Taking a look at that it makes sense now. Thanks to both of you for the help.

Unfortunately the chip is implemented as a multi-function driver (mfd), so the code is not un-complicated. Still fairly straightforward and well-written once you learn your way around it, though. Basically, it implements a core set of functionality to talk to the actual chip registers, which is bus-agnostic. Then the bus-specific drivers use these functions when they actually want to touch the chip itself. In other words, exactly what David suggested. b.g.
