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.

- xlnx,num-transfer-bits : Number of bits per transfer. This will be 8 if not specified



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>;

			xlnx,num-transfer-bits = <32>;

	};
