| 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. |
