3Required properties:
4- compatible		: Must be "adi,axi-spi-engine-1.00.a""
5- reg			: Physical base address and size of the register map.
6- interrupts		: Property with a value describing the interrupt
7			  number.
8- clock-names		: List of input clock names - "s_axi_aclk", "spi_clk"
9- clocks		: Clock phandles and specifiers (See clock bindings for
10			  details on clock-names and clocks).
11- #address-cells	: Must be <1>
12- #size-cells		: Must be <0>
13
14Optional subnodes:
15	Subnodes are use to represent the SPI slave devices connected to the SPI
16	master. They follow the generic SPI bindings as outlined in spi-bus.txt.

24		clocks = <&clkc 15 &clkc 15>;
25		clock-names = "s_axi_aclk", "spi_clk";

27		#address-cells = <1>;
28		#size-cells = <0>;
