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 and myself Chris Morgan . 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.
