1* Marvell XOR engines
2
3Required properties:
4- compatible: Should be "marvell,orion-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
15And the following optional properties:
16- dmacap,memcpy to indicate that the XOR channel is capable of memcpy operations
17- dmacap,memset to indicate that the XOR channel is capable of memset operations
18- dmacap,xor to indicate that the XOR channel is capable of xor operations
19
20Example:
21
22xor@d0060900 {
23 compatible = "marvell,orion-xor";
24 reg = <0xd0060900 0x100
25 0xd0060b00 0x100>;
26 clocks = <&coreclk 0>;
27 status = "okay";
28
29 xor00 {
30 interrupts = <51>;
31 dmacap,memcpy;
32 dmacap,xor;
33 };
34 xor01 {
35 interrupts = <52>;
36 dmacap,memcpy;
37 dmacap,xor;
38 dmacap,memset;
39 };
40};
