+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>;
+ };
