* Xillybus driver for generic FPGA interface
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: Should be "xillybus,xillybus-1.00.a"
|
||||||
|
- reg: Address and length of the register set for the device
|
||||||
|
- interrupts: Contains one interrupt node, typically consisting of three cells.
|
||||||
|
- interrupt-parent: the phandle for the interrupt controller that
|
||||||
|
services interrupts for this device.
|
||||||
|
|
||||||
|
Optional properties:
|
||||||
|
- dma-coherent: Present if DMA operations are coherent
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
xillybus@ff200400 {
|
||||||
|
compatible = "xillybus,xillybus-1.00.a";
|
||||||
|
reg = < 0xff200400 0x00000080 >;
|
||||||
|
interrupts = < 0 40 1 >;
|
||||||
|
interrupt-parent = <&intc>;
|
||||||
|
} ;
