The driver also provides some additional useful values via debugfs, which 72do not fit into the hwmon class. 73 74Debugfs entries 75--------------- 76 77======================= ======================================================== 78uptime Current uptime of the psu 79uptime_total Total uptime of the psu 80vendor Vendor name of the psu 81product Product name of the psu 82======================= ======================================================== 83
