Zynq SPI controller Device Tree Bindings
|
||
|
|
----------------------------------------
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : Should be "xlnx,spi-zynq".
|
||
|
|
- reg : Physical base address and size of SPI registers map.
|
||
|
|
- status : Status will be disabled in dtsi and enabled in required dts.
|
||
|
|
- interrupt-parent : Must be core interrupt controller.
|
||
|
|
- interrupts : Property with a value describing the interrupt
|
||
|
|
number.
|
||
|
|
- clocks : Clock phandles (see clock bindings for details).
|
||
|
|
- clock-names : List of input clock names - "ref_clk", "pclk"
|
||
|
|
(See clock bindings for details).
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
spi@e0006000 {
|
||
|
|
compatible = "xlnx,zynq-spi";
|
||
|
|
reg = <0xe0006000 0x1000>;
|
||
|
|
status = "disabled";
|
||
|
|
interrupt-parent = <&intc>;
|
||
|
|
interrupts = <0 26 4>;
|
||
|
|
clocks = <&clkc 25>, <&clkc 34>;
|
||
|
|
clock-names = "ref_clk", "pclk";
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
} ;
