2-------------------------------------------------
3
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.
9
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>;
22 };
