I mean to add those two pointers to bus_recinovery_info and if they are
populated, then the I2C core is doing the necessary magic (or maybe just
the pinctrl handle and assume the states have fixed names?). Russell
just sent patches to add it to the PXA driver, so we could now double
check how much could be factored out.

I haven't started yet, let's keep in touch who started first :)
