+Kernel driver max8688
+=====================
+
+Supported chips:
+ * Maxim MAX8688
+ Prefix: 'max8688'
+ Addresses scanned: -
+ Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX8688.pdf
+
+Author: Guenter Roeck <linux@roeck-us.net>
+
+
+Description
+-----------
+
+This driver supports hardware montoring for Maxim MAX8688 Digital Power-Supply
+Controller/Monitor with PMBus Interface.
+
+The driver is a client driver to the core PMBus driver. Please see
+Documentation/hwmon/pmbus 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.
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported. Limits are read-write; all other
+attributes are read-only.
+
+in1_label "vout1"
+in1_input Measured voltage. From READ_VOUT register.
+in1_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
+in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
+in1_lcrit Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
+in1_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
+in1_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
+in1_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
+in1_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
+in1_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
+in1_highest Historical maximum voltage.
+in1_reset_history Write any value to reset history.
+
+curr1_label "iout1"
+curr1_input Measured current. From READ_IOUT register.
+curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
+curr1_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
+curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT register.
+curr1_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status.
+curr1_highest Historical maximum current.
+curr1_reset_history Write any value to reset history.
+
+temp1_input Measured temperature. From READ_TEMPERATURE_1 register.
+temp1_max Maximum temperature. From OT_WARN_LIMIT register.
+temp1_crit Critical high temperature. From OT_FAULT_LIMIT register.
+temp1_max_alarm Chip temperature high alarm. Set by comparing
+ READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
+ status is set.
+temp1_crit_alarm Chip temperature critical high alarm. Set by comparing
+ READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
+ status is set.
+temp1_highest Historical maximum temperature.
+temp1_reset_history Write any value to reset history.
