Please see 33Documentation/hwmon/pmbus.rst for details on PMBus client drivers. 34 35Usage Notes 36----------- 37 38This driver does not auto-detect devices. You will have to instantiate 39the devices explicitly. 40 41Sysfs entries 42------------- 43 44================= ======================================== 45in1_label "vin" 46in1_input Measured input voltage 47in1_alarm Input voltage alarm 48in2_label "vout1" 49in2_input Measured output voltage 50in2_alarm Output voltage alarm 51curr1_label "iout1" 52curr1_input Measured output current 53curr1_alarm Output current alarm 54temp1_input Measured temperature 55temp1_alarm Chip temperature alarm 56temp2_input Measured temperature (secondary) 57================= ======================================== 58
