     37Description
     38-----------
     39
     40This driver supports hardware monitoring for Flex PIM4328 and
     41compatible digital power interface modules.
     42
     43The driver is a client driver to the core PMBus driver. Please see
     44Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core for details
     45on PMBus client drivers.
     46
     47
     48Usage Notes
     49-----------
     50
     51This driver does not auto-detect devices. You will have to instantiate the
     52devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
     53details.
     54
     55
     56Platform data support
     57---------------------
     58
     59The driver supports standard PMBus driver platform data.
     60
