Xilinx SPI controller Device Tree Bindings
-------------------------------------------------

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

Optional properties:
- xlnx,num-ss-bits	: Number of chip selects used.

Example:
	axi_quad_spi@41e00000 {
			compatible = "xlnx,xps-spi-2.00.a";
			interrupt-parent = <&intc>;
			interrupts = <0 31 1>;
			reg = <0x41e00000 0x10000>;
			xlnx,num-ss-bits = <0x1>;
	};
