Linux on ARMThe Linux 4.19 kernel will be introducing a new "raspberrypi-hwmon" driver capable of reporting under-voltage conditions for Raspberry Pi boards.

This Raspberry Pi Hwmon driver makes it easy to find out if your ARM SBC is suffering from any under-voltage condition: the driver reports the under-voltage sensor state via a mailbox interface with the VC4 firmware. Undervoltage conditions are then written to the kernel log.
