+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 */
+ };
