We want to get rid of the platform data callbacks here,
there no longer any need to keep these under arch/arm.

Yes, looks like this can all be done in the driver nowadays.
You can use drivers/reset for the set_power. Or if it's really
controlling the regulator, then the regulator framework. The
info can be passed in a .dts file for those.

The .set_current you can do in the driver based on the
compatible flag.

Right, let's get this driver updated to use the device tree
based init and that way this file is no longer needed.
I would like to $ grep -i grandmom ~/.phonebook | call too :)

I forgot how this charger is wired up, but maybe take a
look at commit d7bf353f (bq24190_charger: Add support for TI
BQ24190 Battery Charger) for the DT parts.
