/**

 * 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.
