+Description
+-----------
+
+This driver adds support for reading the built-in temperature sensor on the
+JH7100 RISC-V SoC by StarFive Technology Co. Ltd.
+
+``sysfs`` interface
+-------------------
+
+The temperature sensor can be enabled, disabled and queried via the standard
+hwmon interface in sysfs under ``/sys/class/hwmon/hwmonX`` for some value of
+``X``:
