  Xilinx Zynq UltraScale+ MPSoC GQSPI controller Device Tree Bindings
  -------------------------------------------------------------------
  
  Required properties:
  - compatible		: Should be "xlnx,zynqmp-qspi-1.0".
  - reg			: Physical base address and size of GQSPI registers map.
  - interrupts		: Property with a value describing the interrupt
  			  number.
  - interrupt-parent	: Must be core interrupt controller.
  - clock-names		: List of input clock names - "ref_clk", "pclk"
  			  (See clock bindings for details).
  - clocks		: Clock phandles (see clock bindings for details).
  
  Optional properties:
  - num-cs		: Number of chip selects used.
  
  Example:
  	qspi: spi@ff0f0000 {
  		compatible = "xlnx,zynqmp-qspi-1.0";
  		clock-names = "ref_clk", "pclk";
  		clocks = <&misc_clk &misc_clk>;
  		interrupts = <0 15 4>;
  		interrupt-parent = <&gic>;
  		num-cs = <1>;
  		reg = <0x0 0xff0f0000 0x1000>,<0x0 0xc0000000 0x8000000>;
  	};
