Annotated Snippet
Kernel driver npcm750-pwm-fan
=============================
Supported chips:
NUVOTON NPCM750/730/715/705
Authors:
<tomer.maimon@nuvoton.com>
Description:
------------
This driver implements support for NUVOTON NPCM7XX PWM and Fan Tacho
controller. The PWM controller supports up to 8 PWM outputs. The Fan tacho
controller supports up to 16 tachometer inputs.
The driver provides the following sensor accesses in sysfs:
=============== ======= =====================================================
fanX_input ro provide current fan rotation value in RPM as reported
by the fan to the device.
pwmX rw get or set PWM fan control value. This is an integer
value between 0(off) and 255(full speed).
=============== ======= =====================================================Annotation

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.
