* Marvell XOR v2 engines
Required properties:
- compatible: one of the following values:
"marvell,armada-7k-xor"
"marvell,xor-v2"
- reg: Should contain registers location and length (two sets)
the first set is the DMA registers
the second set is the global registers
- msi-parent: Phandle to the MSI-capable interrupt controller used for
interrupts.
Optional properties:
- clocks: Optional reference to the clock used by the XOR engine.
Example:
xor0@400000 {
compatible = "marvell,xor-v2";
reg = <0x400000 0x1000>,
<0x410000 0x1000>;
msi-parent = <&gic_v2m0>;
dma-coherent;
};
