From: Chris Morgan <macromorgan at hotmail.com>

As this is my first charger driver, I'm submitting it as an RFC so I
can get input from the community on what else is needed to make the
driver consistent with the quality upstream expects.

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 <maccraft123mc at gmail.com> and
myself Chris Morgan <macromorgan at hotmail.com>.

The driver requires some basic parameters be described about the
battery in the devicetree such as the maximum capacity, the minimum
and maximum voltage for the battery, the maximum charge current, the
maximum charge voltage, and the value of sample resistors and sleep
currents.
