2-------------------------------------------------------------------
3
4Required properties:
5- compatible : Should be "xlnx,zynqmp-qspi-1.0".
6- reg : Physical base address and size of GQSPI registers map.
7- interrupts : Property with a value describing the interrupt
8 number.
9- clock-names : List of input clock names - "ref_clk", "pclk"
10 (See clock bindings for details).
11- clocks : Clock phandles (see clock bindings for details).

13Optional properties:
14- num-cs : Number of chip selects used.

16Example:
17 qspi: spi@ff0f0000 {
18 compatible = "xlnx,zynqmp-qspi-1.0";
19 clock-names = "ref_clk", "pclk";
20 clocks = <&misc_clk &misc_clk>;
21 interrupts = <0 15 4>;
22 interrupt-parent = <&gic>;
23 num-cs = <1>;
24 reg = <0x0 0xff0f0000 0x1000>,<0x0 0xc0000000 0x8000000>;
25 };
