-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.
-- 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.
-
-Example:
-	qspi: spi@e000d000 {
-		compatible = "xlnx,zynq-qspi-1.0";
-		reg = <0xe000d000 0x1000>;
-		interrupt-parent = <&intc>;
-		interrupts = <0 19 4>;
-		clock-names = "ref_clk", "pclk";
-		clocks = <&clkc 10>, <&clkc 43>;
-		num-cs = <1>;
-	};
