Annotated Snippet

Kernel driver ibm-cffps
=======================

Supported chips:

  * IBM Common Form Factor power supply

Author: Eddie James <eajames@us.ibm.com>

Description
-----------

This driver supports IBM Common Form Factor (CFF) power supplies. This driver
is a client to the core PMBus driver.

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.

curr1_input		Measured output current in mA.
curr1_label		"iout1"

fan1_alarm		Fan 1 warning.
fan1_fault		Fan 1 fault.
fan1_input		Fan 1 speed in RPM.
fan2_alarm		Fan 2 warning.

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.
