4Required properties:
5- compatible		: Should be "xlnx,zynq-qspi-1.0".
6- reg			: Physical base address and size of QSPI 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).
12
13Optional properties:
14- num-cs		: Number of chip selects used.

16Example:
17	qspi: spi@e000d000 {
18		compatible = "xlnx,zynq-qspi-1.0";
19		reg = <0xe000d000 0x1000>;
20		interrupt-parent = <&intc>;
21		interrupts = <0 19 4>;
22		clock-names = "ref_clk", "pclk";
23		clocks = <&clkc 10>, <&clkc 43>;
24		num-cs = <1>;
25	};
