   3 Required 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>

  14 Optional 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.

  20     spi@@44a00000 {
  21                 compatible = "adi,axi-spi-engine-1.00.a";
  22                 reg = <0x44a00000 0x1000>;
  23                 interrupts = <0 56 4>;
  24                 clocks = <&clkc 15 &clkc 15>;
  25                 clock-names = "s_axi_aclk", "spi_clk";
  26
  27                 #address-cells = <1>;
  28                 #size-cells = <0>;
