The wm831x PMICs have an AUXADC with (actual wirings vary depending on the particular device):
- Some voltage inputs hard wired to particular system supplies. - One or more temperature inputs wired to particular place (eg, chip and battery). - Some channels that measure voltages on some of the pins with no particular function allocated to them.
