Kernel driver ibm-cffps ======================= Supported chips: * IBM Common Form Factor power supply Author: Eddie James <eajames@us.ibm.com> Description ----------- This driver supports IBM Common Form Factor (CFF) power supplies. This driver is a client to the core PMBus driver. 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. Sysfs entries ------------- The following attributes are supported: ======================= ====================================================== curr1_alarm Output current over-current alarm. curr1_input Measured output current in mA. curr1_label "iout1" fan1_alarm Fan 1 warning. fan1_fault Fan 1 fault. fan1_input Fan 1 speed in RPM. fan2_alarm Fan 2 warning. fan2_fault Fan 2 fault. fan2_input Fan 2 speed in RPM. in1_alarm Input voltage under-voltage alarm. in1_input Measured input voltage in mV. in1_label "vin" in2_alarm Output voltage over-voltage alarm. in2_input Measured output voltage in mV. in2_label "vout1" power1_alarm Input fault or alarm. power1_input Measured input power in uW. power1_label "pin" temp1_alarm PSU inlet ambient temperature over-temperature alarm. temp1_input Measured PSU inlet ambient temp in millidegrees C. temp2_alarm Secondary rectifier temp over-temperature alarm. temp2_input Measured secondary rectifier temp in millidegrees C. temp3_alarm ORing FET temperature over-temperature alarm. temp3_input Measured ORing FET temperature in millidegrees C. ======================= ======================================================
