Debugfs can be used to call firmware APIs with required parameters. Usage: * Calling firmware API through debugfs: # echo "<api-name> <arg1> .. <argn>" > /sys/.../zynqmp-firmware/pm * Read output of last called firmware API: # cat /sys/.../zynqmp-firmware/pm Refer ug1200 for more information on these APIs: * https://www.xilinx.com/support/documentation/user_guides/ug1200-eemi-api.pdf Add basic debugfs file to get API version.
