The +LTP8800 is a family of step-down μModule regulators that provides microprocessor +core voltage from 54V power distribution architecture. Through the PMBus +interface, the device can monitor input/output voltages, input current and +temperature. + +Usage Notes +----------- + +This driver does not auto-detect devices. You will have to instantiate +the devices explicitly. +Please see Documentation/i2c/instantiating-devices.rst for details. + +Platform data support +--------------------- + +The driver supports standard PMBus driver platform data. + +Sysfs Attributes +---------------- + +================= ======================================== +in1_label "vin" +in1_input Measured input voltage +in1_alarm Input voltage alarm +in1_crit Critical maximum input voltage +in1_crit_alarm Input voltage high alarm +in1_lcrit Critical minimum input voltage +in1_lcrit_alarm Input voltage critical low alarm +in2_label "vout1" +in2_input Measured output voltage +in2_crit Critical maximum output voltage +in2_crit_alarm Output voltage high alarm +in2_lcrit Critical minimum output voltage +in2_lcrit_alarm Output voltage critical low alarm +in2_max Critical maximum output voltage +in2_max_alarm Output voltage critical max alarm +in2_min Critical minimum output voltage +in2_min_alarm Output voltage critical min alarm +curr1_label "iin" +curr1_input Measured input current. +curr1_alarm Input current alarm +curr1_crit Critical maximum input current +curr1_crit_alarm Input current high alarm +curr2_label "iout1" +curr2_input Measured output current +curr2_alarm Output current alarm +curr2_crit Critical maximum output current +curr2_crit_alarm Output current high alarm +curr2_lcrit Critical minimum output current +curr2_lcrit_alarm Output current critical low alarm +curr2_max Critical maximum output current +curr2_max_alarm Output current critical max alarm +power1_label "pout1" +power1_input Measured output power +power1_crit Critical maximum output power +power1_crit_alarm Output power high alarm +temp1_input Measured temperature +temp1_crit Critical high temperature +temp1_crit_alarm Chip temperature critical high alarm +temp1_max Critical maximum temperature +temp1_max_alarm Temperature critical max alarm +temp2_input Measured temperature +temp2_crit Critical high temperature +temp2_crit_alarm Chip temperature critical high alarm +temp2_max Critical maximum temperature +temp2_max_alarm Temperature critical max alarm +================= ======================================== |
