SPDX-License-Identifier: GPL-2.0 + +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 + +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** -- cgit v1.2.3
