-Description
------------
-
-This driver supports hardware montoring for Maxim MAX34440 PMBus 6-Channel
-Power-Supply Manager, MAX34441 PMBus 5-Channel Power-Supply Manager
-and Intelligent Fan Controller, and MAX34446 PMBus Power-Supply Data Logger.
-
-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.
-
-For MAX34446, the value of the currX_crit attribute determines if current or
-voltage measurement is enabled for a given channel. Voltage measurement is
-enabled if currX_crit is set to 0; current measurement is enabled if the
-attribute is set to a positive value. Power measurement is only enabled if
-channel 1 (3) is configured for voltage measurement, and channel 2 (4) is
-configured for current measurement.
-
-
-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.
-
-in[1-6]_label "vout[1-6]".
-in[1-6]_input Measured voltage. From READ_VOUT register.
-in[1-6]_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
-in[1-6]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
-in[1-6]_lcrit Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
-in[1-6]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
-in[1-6]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
-in[1-6]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
-in[1-6]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
-in[1-6]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
-in[1-6]_lowest Historical minimum voltage.
-in[1-6]_highest Historical maximum voltage.
-in[1-6]_reset_history Write any value to reset history.
-
- MAX34446 only supports in[1-4].
-
