I've got a board with a max31331 so I can test that. I don't have any of
the interrupts hooked up so I won't be able to test that. Looks like
there was some outstanding discussion around the trickle-charge
devicetree properties so I'd need to figure out what was wanted there.
I'll try to pick up the last series from the mailing list and go from there.
