+Xilinx Zynq QSPI controller Device Tree Bindings
+-------------------------------------------------
+
+Required properties:
+- compatible : Should be "xlnx,zynq-qspi-1.0".
+- reg : Physical base address and size of QSPI registers map.
+- interrupts : Property with a value describing the interrupt
+ number.
+- interrupt-parent : Must be core interrupt controller
+- clock-names : List of input clock names - "ref_clk", "pclk"
+ (See clock bindings for details).
+- clocks : Clock phandles (see clock bindings for details).
+
+Optional properties:
+- num-cs : Number of chip selects used.
+- is-dual : QSPI operating in Dual parallel.
+- is-satcked : QSPI operating in Stacked mode.
+
+Example:
+ qspi@e000d000 {
+ compatible = "xlnx,zynq-qspi-1.0";
+ clock-names = "ref_clk", "pclk";
+ clocks = <&clkc 10>, <&clkc 43>;
+ interrupt-parent = <&intc>;
+ interrupts = <0 19 4>;
+ num-cs = <1>;
+ reg = <0xe000d000 0x1000>;
+ } ;
