Xilinx Zynq UltraScale+ MPSoC GQSPI controller Device Tree Bindings
-------------------------------------------------------------------

Required properties:
- compatible		: Should be "xlnx,zynqmp-qspi-1.0".
- reg			: Physical base address and size of GQSPI 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.

Example:
	qspi: spi@ff0f0000 {
		compatible = "xlnx,zynqmp-qspi-1.0";
		clock-names = "ref_clk", "pclk";
		clocks = <&misc_clk &misc_clk>;
		interrupts = <0 15 4>;
		interrupt-parent = <&gic>;
		num-cs = <1>;
		reg = <0x0 0xff0f0000 0x1000>,<0x0 0xc0000000 0x8000000>;
	};
