/**
* DOC: acoustic_target_rpm_threshold
*
* The amdgpu driver provides a sysfs API for checking and adjusting the
* acoustic target 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 can co-exist with
* other settings which can work also under auto mode. It adjusts the PMFW's
* behavior about the maximum speed in RPM the fan can spin when ASIC
* temperature is not greater than target temperature. Setting via this
* interface will switch the fan control to auto mode implicitly.
