* Marvell XOR engines



Required properties:

- compatible: Should be "marvell,orion-xor"

- reg: Should contain registers location and length (two sets)

    the first set is the low registers, the second set the high

    registers for the XOR engine.

- clocks: pointer to the reference clock



The DT node must also contains sub-nodes for each XOR channel that the

XOR engine has. Those sub-nodes have the following required

properties:

- interrupts: interrupt of the XOR channel



And the following optional properties:

- dmacap,memcpy to indicate that the XOR channel is capable of memcpy operations

- dmacap,memset to indicate that the XOR channel is capable of memset operations

- dmacap,xor to indicate that the XOR channel is capable of xor operations



Example:



xor@d0060900 {

	compatible = "marvell,orion-xor";

	reg = <0xd0060900 0x100

	       0xd0060b00 0x100>;

	clocks = <&coreclk 0>;

	status = "okay";



	xor00 {

	      interrupts = <51>;

	      dmacap,memcpy;

	      dmacap,xor;

	};

	xor01 {

	      interrupts = <52>;

	      dmacap,memcpy;

	      dmacap,xor;

	      dmacap,memset;

	};

};
