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 additional non-sensor information
like uptimes.
