+ * DOC: fan_zero_rpm_stop_temperature
+ *
+ * The amdgpu driver provides a sysfs API for checking and adjusting the
+ * zero RPM stop temperature feature.
+ *
+ * Reading back the file shows you the current setting and the permitted
+ * ranges if changable.
+ *
+ * Writing an integer to the file, change the setting accordingly.
+ *
+ * When you have finished the editing, write "c" (commit) to the file to commit
+ * your changes.
+ *
+ * If you want to reset to the default value, write "r" (reset) to the file to
+ * reset them.
+ *
+ * This setting works only if the Zero RPM setting is enabled. It adjusts the
+ * temperature below which the fan can stop.
