Kernel driver POWERZ
====================
Supported chips:
* ChargerLAB POWER-Z KM003C
Prefix: 'powerz'
Addresses scanned: -
Author:

Description
-----------
This driver implements support for the ChargerLAB POWER-Z USB-C power testing
family.
The device communicates with the custom protocol over USB.
The channel labels exposed via hwmon match the labels used by the on-device
display and the official POWER-Z PC software.
As current can flow in both directions through the tester the sign of the
channel "curr1_input" (label "IBUS") indicates the direction.
