Subject[PATCH v3 5/5] ARM: dts: axp209: Add iio-hwmon node for internal temperature
This adds a DT node to hook up the internal temperature ADC to the
iio-hwmon driver. The various voltage + current ADCs are consumed and
exposed by their respective drivers, but this is not and is always
available. Naming chosen to match the axp20x_ prefix the power sensors
use.
