[PATCH v2] power: tps65217_charger: Add properties like voltage and current charge

[PATCH v2] power: tps65217_charger: Add properties like voltage and current charge

[Enric Balletbo i Serra]

Allow the possibility to configure the charge and the current voltage of
the charger and also the NTC type for battery temperature measurement.

Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com>

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

These two are battery specific. Please use newly introduced
"simple-battery" instead. See

This looks fine. Might make sense to move this into its own patch.

struct power_supply_battery_info info = {};
power_supply_get_battery_info(tps65217, &info);

The simple-battery framework does not yet provide charge
current/voltage, so you will need to add that first. Please
Cc Liam on that patch.

Please use device_property_read_u32(dev, ...) instead.
