The KEBA battery monitoring controller is found in the system FPGA of
KEBA PLC devices. It puts a load on the coin cell battery to check the
state of the battery. If the coin cell battery is nearly empty, then
the user space is signaled with a hwmon alarm.

The auxiliary device for this driver is instantiated by the cp500 misc
driver.
