^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) The WM831x series of PMICs include an AUXADC which can be used to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) monitor a range of system operating parameters, including the voltages
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) of the major supplies within the system.  Currently the driver provides
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) reporting of all the input values but does not provide any alarms.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) Voltage Monitoring
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) ------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) Voltages are sampled by a 12 bit ADC.  Voltages in millivolts are 1.465
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) times the ADC value.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) Temperatures are sampled by a 12 bit ADC.  Chip and battery temperatures
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) are available.  The chip temperature is calculated as:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 	Degrees celsius = (512.18 - data) / 1.0983
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) while the battery temperature calculation will depend on the NTC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) thermistor component.
