+This driver supports hardware montoring for Analog Devices ADM1275 Hot-Swap
+Controller and Digital Power Monitor.
+The ADM1275 is a hot-swap controller that allows a circuit board to be removed
+from or inserted into a live backplane. It also features current and voltage
+readback via an integrated 12-bit analog-to-digital converter (ADC), accessed
+using a PMBus. interface.
+The driver is a client driver to the core PMBus driver. Please see
+Documentation/hwmon/pmbus for details on PMBus client drivers.
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices for
+Platform data support
+The driver supports standard PMBus driver platform data. Please see
+Documentation/hwmon/pmbus for details.
+The following attributes are supported. Limits are read-write; all other
+attributes are read-only.
+in1_label "vin1" or "vout1" depending on chip variant and
+in1_input Measured voltage. From READ_VOUT register.
+in1_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
+in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
+in1_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
+in1_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
+curr1_input Measured current. From READ_IOUT register.
+curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
+curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT register.
