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.


Sysfs entries
-------------

The following attributes are supported. All attributes are read-only.

======================= ========================================================
in1_label		"vin"
in1_input		Measured input voltage.
in1_alarm		Input voltage alarm.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
