- Description
- -----------
- This driver supports hardware monitoring for Flex PIM4328 and
- compatible digital power interface modules.
- The driver is a client driver to the core PMBus driver. Please see
- Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core 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.rst for
- details.
- Platform data support
- ---------------------
- The driver supports standard PMBus driver platform data.
