+Kernel driver ibmps
+====================
+
+Supported chips:
+  * IBM Witherspoon power supply
+
+Author: Eddie James <eajames@...ibm.com>
+
+Description
+-----------
+
+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.
