- 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 <[email protected]>
- 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**
