[PATCH v3 1/4] dt-bindings: power: supply: add battery charge voltage/current

From: Enric Balletbo i Serra
Date: Fri May 26 2017 - 07:04:29 EST


Add charging voltage and current characteristics to the battery DT for
proper handling of the battery by fuel-gauge and charger chips.

Changes since v2:
- Requested by Sebastian Reichel
- Move to its own patch and apply to simple-battery framework.
Changes since v1:
