The driver is a client driver to the core PMBus driver. Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. Usage Notes ----------- This driver does not auto-detect devices. You will have to instantiate the devices explicitly. Please see Documentation/i2c/instantiating-devices for details. Platform data support --------------------- The driver supports standard PMBus driver platform data. Sysfs entries ------------- The following attributes are supported. Limits are read-write; all other attributes are read-only. ======================= ======================================================= in1_label "vin" in1_input Measured input voltage. in1_average Average measured input voltage. in1_min Minimum input voltage. in1_max Maximum input voltage. in1_min_alarm Input voltage low alarm. in1_max_alarm Input voltage high alarm. in2_label "vmon" in2_input Measured voltage on VAUX pin in2_min Minimum VAUX voltage (LM25056 only). in2_max Maximum VAUX voltage (LM25056 only). in2_min_alarm VAUX voltage low alarm (LM25056 only). in2_max_alarm VAUX voltage high alarm (LM25056 only). in3_label "vout1" Not supported on LM25056. in3_input Measured output voltage. in3_average Average measured output voltage. in3_min Minimum output voltage. in3_min_alarm Output voltage low alarm. curr1_label "iin" curr1_input Measured input current. curr1_average Average measured input current. curr1_max Maximum input current. curr1_max_alarm Input current high alarm. power1_label "pin" power1_input Measured input power. power1_average Average measured input power. power1_max Maximum input power limit. power1_alarm Input power alarm power1_input_highest Historical maximum power. power1_reset_history Write any value to reset maximum power history. temp1_input Measured temperature. temp1_max Maximum temperature. temp1_crit Critical high temperature. temp1_max_alarm Chip temperature high alarm. temp1_crit_alarm Chip temperature critical high alarm. ======================= =======================================================
