12 description: The zynqmp-firmware node describes the interface to platform
13 firmware. ZynqMP has an interface to communicate with secure firmware.
14 Firmware driver provides an interface to firmware APIs. Interface APIs
15 can be used by any driver to communicate to PMUFW(Platform Management Unit).
16 These requests include clock management, pin control, device control,
17 power management service, FPGA service and other platform management
