    2 Device Tree Bindings for the Xilinx Zynq MPSoC Firmware Interface
    3 -----------------------------------------------------------------
    4 
    5 The zynqmp-firmware node describes the interface to platform firmware.
    6 ZynqMP has an interface to communicate with secure firmware. Firmware
    7 driver provides an interface to firmware APIs. Interface APIs can be
    8 used by any driver to communicate to PMUFW(Platform Management Unit).
    9 These requests include clock management, pin control, device control,
   10 power management service, FPGA service and other platform management
   11 services.
   12 
   13 Required properties:
   14  - compatible:  Must contain any of below:
   15                 "xlnx,zynqmp-firmware" for Zynq Ultrascale+ MPSoC
   16                 "xlnx,versal-firmware" for Versal
   17  - method:      The method of calling the PM-API firmware layer.
   18                 Permitted values are:
   19                   - "smc" : SMC #0, following the SMCCC
   20                   - "hvc" : HVC #0, following the SMCCC
