+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**
