+Kernel driver ibmps
+Supported chips:
+ * IBM Witherspoon power supply
+Author: Eddie James <eajames@xxxxxxxxxx>
+This driver supports the IBM power supply. This driver is a client to the core
+PMBus driver.
+Usage Notes
+This driver should auto-detect devices. In the event that it does not, you will
+have to instantiate the devices explicitly. Please see
+Documentation/i2c/instantiating-devices for details.
+Sysfs entries
+The following attributes are supported:
+curr1_alarm Output current over-current fault.
+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 fault.
+in1_input Measured input voltage in mV.
+in1_label "vin"
+in2_alarm Output voltage over-voltage fault.
+in2_input Measured output voltage in mV.
+in2_label "vout1"
+power1_input Measured input power in uW.
+power1_label "pin"
+temp1_alarm PSU inlet ambient temperature over-temperature fault.
+temp1_input Measured PSU inlet ambient temp in millidegrees C.
+temp2_alarm Secondary rectifier temp over-temperature fault.
+temp2_input Measured secondary rectifier temp in millidegrees C.
+temp3_alarm ORing FET temperature over-temperature fault.
+temp3_input Measured ORing FET temperature in millidegrees C.
