Kernel driver lan966x-hwmon
===========================
Supported chips:
* Microchip LAN9668 (sensor in SoC)
Prefix: 'lan9668-hwmon'
Datasheet: https://microchip-ung.github.io/lan9668_reginfo
Authors:
Michael Walle <michael@walle.cc>
Description
-----------
This driver implements support for the Microchip LAN9668 on-chip
temperature sensor as well as its fan controller. It provides one
temperature sensor and one fan controller. The temperature range
of the sensor is specified from -40 to +125 degrees Celsius and
its accuracy is +/- 5 degrees Celsius. The fan controller has a
tacho input and a PWM output with a customizable PWM output
frequency ranging from ~20Hz to ~650kHz.
No alarms are supported by the SoC.
The driver exports temperature values, fan tacho input and PWM
settings via the following sysfs files:
**temp1_input**
**fan1_input**
**pwm1**
**pwm1_freq**
Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
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.
