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.
