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.
