PMBus telemetry 27feature provides information regarding the output voltage and current, 28input voltage, bias voltage and die temperature. 29 30The driver is a client driver to the core PMBus driver. Please see 31Documentation/hwmon/pmbus.rst for details on PMBus client drivers. 32 33Usage Notes 34----------- 35 36This driver does not auto-detect devices. You will have to instantiate 37the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst 38for details. 39 40Platform data support 41--------------------- 42 43The driver supports standard PMBus driver platform data. 44 45Sysfs entries 46------------- 47 48======================= ======================================================= 49in1_label "vin" 50in1_input Measured input voltage 51in1_max Input overvoltage warning limit 52in1_max_alarm Input overvoltage warning status 53in1_min Input undervoltage warning limit 54in1_min_alarm Input undervoltage warning status 55in2_label "vmon" 56in2_input Measured bias voltage 57in2_max Bias overvoltage warning limit 58in2_min Bias undervoltage warning limit 59in3_label "vout1" 60in3_input Measured output voltage 61in3_max Output overvoltage warning limit 62in3_max_alarm Output overvoltage warning status 63in3_min Output undervoltage warning limit 64in3_min_alarm Output undervoltage warning status 65curr1_label "iout1" 66curr1_input Measured output current. 67curr1_crit Output overcurrent fault limit 68curr1_crit_alarm Output overcurrent fault status 69temp1_input Measured temperature 70temp1_max Maximum temperature limit 71temp1_max_alarm Overtemperature warning status 72======================= ======================================================= 73
