Xilinx SPI controller Device Tree Bindings
|
-------------------------------------------------
|
|
Required properties:
|
- compatible : Should be "xlnx,xps-spi-2.00.a", "xlnx,xps-spi-2.00.b" or "xlnx,axi-quad-spi-1.00.a"
|
- reg : Physical base address and size of SPI registers map.
|
- interrupts : Property with a value describing the interrupt
|
number.
|
|
Optional properties:
|
- xlnx,num-ss-bits : Number of chip selects used.
|
- xlnx,num-transfer-bits : Number of bits per transfer. This will be 8 if not specified
|
|
Example:
|
axi_quad_spi@41e00000 {
|
compatible = "xlnx,xps-spi-2.00.a";
|
interrupt-parent = <&intc>;
|
interrupts = <0 31 1>;
|
reg = <0x41e00000 0x10000>;
|
xlnx,num-ss-bits = <0x1>;
|
xlnx,num-transfer-bits = <32>;
|
};
