/**
* DOC: fan_curve
*
* The amdgpu driver provides a sysfs API for checking and adjusting the fan
* control curve line.
*
* Reading back the file shows you the current settings(temperature in Celsius
* degree and fan speed in pwm) applied to every anchor point of the curve line
* and their permitted ranges if changable.
*
* Writing a desired string(with the format like "anchor_point_index temperature
* fan_speed_in_pwm") to the file, change the settings for the specific anchor
* point accordingly.
*
* When you have finished the editing, write "c" (commit) to the file to commit
* your changes.
*
* There are two fan control modes supported: auto and manual. With auto mode,
* PMFW handles the fan speed control(how fan speed reacts to ASIC temperature).
* While with manual mode, users can set their own fan curve line as what
* described here. Normally the ASIC is booted up with auto mode. Any
* settings via this interface will switch the fan control to manual mode
* implicitly.
