1* Marvell XOR engines
2
3Required properties:
4- compatible: Should be "marvell,orion-xor" or "marvell,armada-380-xor"
5- reg: Should contain registers location and length (two sets)
6    the first set is the low registers, the second set the high
7    registers for the XOR engine.
8- clocks: pointer to the reference clock
9
10The DT node must also contains sub-nodes for each XOR channel that the
11XOR engine has. Those sub-nodes have the following required
12properties:
13- interrupts: interrupt of the XOR channel
14
15The sub-nodes used to contain one or several of the following
16properties, but they are now deprecated:
17- dmacap,memcpy to indicate that the XOR channel is capable of memcpy operations
18- dmacap,memset to indicate that the XOR channel is capable of memset operations
19- dmacap,xor to indicate that the XOR channel is capable of xor operations
20- dmacap,interrupt to indicate that the XOR channel is capable of
21  generating interrupts
22
23Example:
24
25xor@d0060900 {
26	compatible = "marvell,orion-xor";
27	reg = <0xd0060900 0x100
28	       0xd0060b00 0x100>;
29	clocks = <&coreclk 0>;
30	status = "okay";
31
32	xor00 {
33	      interrupts = <51>;
34	};
35	xor01 {
36	      interrupts = <52>;
37	};
38};
