-Description
------------
-
-This driver supports TI TPS40422 Dual-Output or Two-Phase Synchronous Buck
-Controller with PMBus
-
-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.
-
-in[1-2]_label "vout[1-2]"
-in[1-2]_input Measured voltage. From READ_VOUT register.
-in[1-2]_alarm voltage alarm.
-
-curr[1-2]_input Measured current. From READ_IOUT register.
-curr[1-2]_label "iout[1-2]"
-curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
