Annotated Snippet
Kernel driver menf21bmc_hwmon
=============================
Supported chips:
* MEN 14F021P00
Prefix: 'menf21bmc_hwmon'
Addresses scanned: -
Author: Andreas Werner <andreas.werner@men.de>
Description
-----------
The menf21bmc is a Board Management Controller (BMC) which provides an I2C
interface to the host to access the features implemented in the BMC.
This driver gives access to the voltage monitoring feature of the main
voltages of the board.
The voltage sensors are connected to the ADC inputs of the BMC which is
a PIC16F917 Mikrocontroller.
Usage Notes
-----------
This driver is part of the MFD driver named "menf21bmc" and does
not auto-detect devices.
You will have to instantiate the MFD driver explicitly.
Please see Documentation/i2c/instantiating-devices.rst for
details.
Sysfs entries

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.
