Currently there is no easy way to detect under-voltage conditions on a remote
Raspberry Pi. This hwmon driver retrieves the state of the under-voltage sensor
via mailbox interface. The handling based on Noralf's modifications to the
downstream firmware driver. In case of an under-voltage condition only an entry
is written to the kernel log.

My major concern is how this is displayed with the 'sensors' command.
Can you test and report ?

I get the following output:
rpi_volt-isa-0000
Adapter: ISA adapter
in0:              N/A  

Ok, that works.

Thanks for the quick review on this, Guenter!  This driver is going to
help save a lot of people debugging time on rpis in the upstream kernel.
