* 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>;
} ;
