+Zynq SPI controller Device Tree Bindings
+----------------------------------------
+
+Required properties:
+- compatible : Should be "xlnx,spi-zynq".
+- reg : Physical base address and size of SPI registers map.
+- status : Status will be disabled in dtsi and enabled in required dts.
+- interrupt-parent : Must be core interrupt controller.
+- interrupts : Property with a value describing the interrupt
+ number.
+- clocks : Clock phandles (see clock bindings for details).
+- clock-names : List of input clock names - "ref_clk", "pclk"
+ (See clock bindings for details).
+
+Example:
+
+ spi at e0006000 {
+ compatible = "xlnx,zynq-spi";
+ reg = <0xe0006000 0x1000>;
+ status = "disabled";
+ interrupt-parent = <&intc>;
+ interrupts = <0 26 4>;
+ clocks = <&clkc 25>, <&clkc 34>;
+ clock-names = "ref_clk", "pclk";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ } ;
