- Description
- -----------
- This driver implements the sysfs interface for the Corsair PSUs with a HID protocol
- interface of the HXi and RMi series.
- These power supplies provide access to a micro-controller with 2 attached
- temperature sensors, 1 fan rpm sensor, 4 sensors for volt levels, 4 sensors for
- power usage and 4 sensors for current levels and addtional non-sensor information
- like uptimes.

- ======================= ========================================================
- Usage Notes
- -----------
- It is an USB HID device, so it is auto-detected and supports hot-swapping.
- Flickering values in the rail voltage levels can be an indicator for a failing
- PSU. The driver also provides some additional useful values via debugfs, which
- do not fit into the hwmon class.

- uptime Session uptime of the psu
- uptime_total Total uptime of the psu
