0037 Description
0038 -----------
0039
0040 This driver supports hardware monitoring for Flex PIM4328 and
0041 compatible digital power interface modules.
0042
0043 The driver is a client driver to the core PMBus driver. Please see
0044 Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core for details
0045 on PMBus client drivers.
0046
0047
0048 Usage Notes
0049 -----------
0050
0051 This driver does not auto-detect devices. You will have to instantiate the
0052 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
0053 details.
