     Analog Devices AXI SPI Engine controller Device Tree Bindings
     
     Required properties:
     - compatible            : Must be "adi,axi-spi-engine-1.00.a""
     - reg                   : Physical base address and size of the register map.
     - interrupts            : Property with a value describing the interrupt
                               number.
     - clock-names           : List of input clock names - "s_axi_aclk", "spi_clk"
     - clocks                : Clock phandles and specifiers (See clock bindings for
                              details on clock-names and clocks).
    - #address-cells        : Must be <1>
    - #size-cells           : Must be <0>
    
    Optional subnodes:
            Subnodes are use to represent the SPI slave devices connected to the SPI
            master. They follow the generic SPI bindings as outlined in spi-bus.txt.
    
    Example:
    
        spi@@44a00000 {
                    compatible = "adi,axi-spi-engine-1.00.a";
                    reg = <0x44a00000 0x1000>;
                    interrupts = <0 56 4>;
                    clocks = <&clkc 15 &clkc 15>;
                    clock-names = "s_axi_aclk", "spi_clk";
    
                    #address-cells = <1>;
                    #size-cells = <0>;
    
                    /* SPI devices */
        };
