This series is to add support for the Rockchip rk817 battery charger
which is present in all Rockchip RK817 PMICs. The driver was written
as a joint effort by Maya Matuszczyk [off-list ref] and
myself Chris Morgan [off-list ref].
Hi Chris and Maya,

Gave this a whirl on my Quartz64 Model A. I noticed that this will
happily let me discharge past voltage_min_design:

 $ cat /sys/class/power_supply/rk817-battery/voltage_min_design 
 3625000
 $ cat /sys/class/power_supply/rk817-battery/voltage_avg 
 3381360

Is this normal? It went all the way to under 3V before the
board finally locked up.

Does the minimum voltage not affect some sort of cutout on
the RK817? Does it even have one? Is it the driver's job to
do something here or not?

Regards,
Nicolas Frattaroli
