-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@...00000 {
-			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>;
-	};
