-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 */
- };

+title: Analog Devices AXI SPI Engine Controller
+
+description: |
+ The AXI SPI Engine controller is part of the SPI Engine framework[1] and
+ allows memory mapped access to the SPI Engine control bus. This allows it
+ to be used as a general purpose software driven SPI controller as well as
+ some optional advanced acceleration and offloading capabilities.
