hwmon: WM831x PMIC hardware monitoring driver
This driver adds support for the hardware monitoring features of the WM831x PMICs to the hwmon API. Monitoring is provided for the system voltages supported natively by the WM831x, the chip temperature, the battery temperature and the auxiliary inputs of the WM831x. Currently no alarms are supported, though digital comparators on the WM831x devices would allow these to be provided. Since the auxiliary and battery temperature input scaling depends on the system configuration the value is reported as a voltage to userspace.
