4Required properties:
5- compatible		: Should be "xlnx,zynqmp-qspi-1.0".
6- reg			: Physical base address and size of GQSPI registers map.
7- interrupts		: Property with a value describing the interrupt
8			  number.
9- clock-names		: List of input clock names - "ref_clk", "pclk"
10			  (See clock bindings for details).
11- clocks		: Clock phandles (see clock bindings for details).

13Optional properties:
14- num-cs		: Number of chip selects used.

16Example:
17	qspi: spi@ff0f0000 {
18		compatible = "xlnx,zynqmp-qspi-1.0";
19		clock-names = "ref_clk", "pclk";
20		clocks = <&misc_clk &misc_clk>;
21		interrupts = <0 15 4>;
22		interrupt-parent = <&gic>;
23		num-cs = <1>;
24		reg = <0x0 0xff0f0000 0x1000>,<0x0 0xc0000000 0x8000000>;
