+Description
+-----------
+
+This driver supports hardware monitoring for Analog Devices ADM1075, ADM1272,
+ADM1275, ADM1276, ADM1278, ADM1293, and ADM1294 Hot-Swap Controller and
+Digital Power Monitors.
+
+ADM1075, ADM1272, ADM1275, ADM1276, ADM1278, ADM1293, and ADM1294 are hot-swap
+controllers that allow a circuit board to be removed from or inserted into
+a live backplane. They also feature 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.rst for details on PMBus client drivers.
+
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices for
+details.
+
+The ADM1075, unlike many other PMBus devices, does not support internal voltage
+or current scaling. Reported voltages, currents, and power are raw measurements,
+and will typically have to be scaled.
+
+The shunt value in micro-ohms can be set via device tree at compile-time. Please
+refer to the Documentation/devicetree/bindings/hwmon/adm1275.txt for bindings
+if the device tree is used.
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data. Please see
+Documentation/hwmon/pmbus.rst for details.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported. Limits are read-write, history reset
+attributes are write-only, all other attributes are read-only.
+
+======================= =======================================================
+inX_label "vin1" or "vout1" depending on chip variant and
+ configuration. On ADM1075, ADM1293, and ADM1294,
+ vout1 reports the voltage on the VAUX pin.
+inX_input Measured voltage.
+inX_min Minimum Voltage.
+inX_max Maximum voltage.
+inX_min_alarm Voltage low alarm.
+inX_max_alarm Voltage high alarm.
+inX_highest Historical maximum voltage.
+inX_reset_history Write any value to reset history.
+
+curr1_label "iout1"
+curr1_input Measured current.
+curr1_max Maximum current.
+curr1_max_alarm Current high alarm.
+curr1_lcrit Critical minimum current. Depending on the chip
+ configuration, either curr1_lcrit or curr1_crit is
+ supported, but not both.
+curr1_lcrit_alarm Critical current low alarm.
+curr1_crit Critical maximum current. Depending on the chip
+ configuration, either curr1_lcrit or curr1_crit is
+ supported, but not both.
+curr1_crit_alarm Critical current high alarm.
+curr1_highest Historical maximum current.
+curr1_reset_history Write any value to reset history.
+
+power1_label "pin1"
+power1_input Input power.
+power1_input_lowest Lowest observed input power. ADM1293 and ADM1294 only.
+power1_input_highest Highest observed input power.
+power1_reset_history Write any value to reset history.
+
+ Power attributes are supported on ADM1075, ADM1272,
+ ADM1276, ADM1293, and ADM1294.
+
+temp1_input Chip temperature.
+temp1_max Maximum chip temperature.
+temp1_max_alarm Temperature alarm.
+temp1_crit Critical chip temperature.
+temp1_crit_alarm Critical temperature high alarm.
+temp1_highest Highest observed temperature.
+temp1_reset_history Write any value to reset history.
+
+ Temperature attributes are supported on ADM1272 and
+ ADM1278.
