1Kernel driver ibm-cffps 2======================= 3 4Supported chips: 5 6 * IBM Common Form Factor power supply 7 8Author: Eddie James <eajames@us.ibm.com> 9 10Description 11----------- 12 13This driver supports IBM Common Form Factor (CFF) power supplies. This driver 14is a client to the core PMBus driver. 15 16Usage Notes 17----------- 18 19This driver does not auto-detect devices. You will have to instantiate the 20devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for 21details. 22 23Sysfs entries 24------------- 25 26The following attributes are supported: 27 28======================= ====================================================== 29curr1_alarm Output current over-current alarm. 30curr1_input Measured output current in mA. 31curr1_label "iout1" 32 33fan1_alarm Fan 1 warning. 34fan1_fault Fan 1 fault. 35fan1_input Fan 1 speed in RPM. 36fan2_alarm Fan 2 warning. 37fan2_fault Fan 2 fault. 38fan2_input Fan 2 speed in RPM. 39 40in1_alarm Input voltage under-voltage alarm. 41in1_input Measured input voltage in mV. 42in1_label "vin" 43in2_alarm Output voltage over-voltage alarm. 44in2_input Measured output voltage in mV. 45in2_label "vout1" 46 47power1_alarm Input fault or alarm. 48power1_input Measured input power in uW. 49power1_label "pin" 50 51temp1_alarm PSU inlet ambient temperature over-temperature alarm. 52temp1_input Measured PSU inlet ambient temp in millidegrees C. 53temp2_alarm Secondary rectifier temp over-temperature alarm. 54temp2_input Measured secondary rectifier temp in millidegrees C. 55temp3_alarm ORing FET temperature over-temperature alarm. 56temp3_input Measured ORing FET temperature in millidegrees C. 57======================= ======================================================
