2232f10d71 hwmon: (powerz) add support for ChargerLAB KM002C 
The KM002C is similar to the KM003C and seems to use the same
protocol and firmware.

4381a36abd hwmon: add POWER-Z driver 
POWER-Z is a series of devices to monitor power characteristics of
USB-C connections and display those on a on-device display.
Some of the devices, notably KM002C and KM003C, contain an additional
port which exposes the measurements via USB.

This is a driver for this monitor port.

It was developed and tested with the KM003C.
