Subject[PATCH v3 2/2] power_supply: Use of-thermal cdev registration API
Date
With thermal frameworks of-thermal interface, thermal zone parameters can
be defined in devicetree. This includes cooling device mitigation levels
for a thermal zone. To take advantage of this, cooling device should use
the thermal_of_cooling_device_register API to register a cooling device.

Use thermal_of_cooling_device_register API to register the power supply
cooling device. This enables power supply cooling device be included in the
thermal zone parameter in devicetree.
