4Required properties:
5- compatible		: Should be "xlnx,xps-spi-2.00.a", "xlnx,xps-spi-2.00.b" or "xlnx,axi-quad-spi-1.00.a"
6- reg			: Physical base address and size of SPI registers map.
7- interrupts		: Property with a value describing the interrupt
8			  number.

10Optional properties:
11- xlnx,num-ss-bits	 : Number of chip selects used.
12- xlnx,num-transfer-bits : Number of bits per transfer. This will be 8 if not specified

14Example:
15	axi_quad_spi@41e00000 {
16			compatible = "xlnx,xps-spi-2.00.a";
17			interrupt-parent = <&intc>;
18			interrupts = <0 31 1>;
19			reg = <0x41e00000 0x10000>;
20			xlnx,num-ss-bits = <0x1>;
21			xlnx,num-transfer-bits = <32>;
