[PATCH v3 2/4] power: supply: core: add charging voltage/current battery info
From: Enric Balletbo i Serra
Date: Fri May 26 2017 - 07:04:33 EST
Add the parameters to define the battery charging voltage and charging
current. Charger driver can get this information from the struct
power_supply_battery_info and apply the desired value.

Changes since v2:
- Requested by Sebastian Reichel
- Move to its own patch and apply to simple-battery framework.
Changes since v1:
- Requested by Rob Herring
- Rename ti,charge-* to charge-* to be standard properties.
- Use unit suffixes as per bindings/property-units.txt
