From: Chris Morgan <redacted> 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
