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 */ | ||
}; |
