+/**
+ * DOC: acoustic_limit_rpm_threshold
+ *
+ * The amdgpu driver provides a sysfs API for checking and adjusting the
+ * acoustic limit in RPM for fan control.
+ *
+ * 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.
+ *
+ * This setting works under auto fan control mode only. It adjusts the PMFW's
+ * behavior about the maximum speed in RPM the fan can spin. Setting via this
+ * interface will switch the fan control to auto mode implicitly.
