* Marvell XOR engines
Required properties:
- compatible: Should be "marvell,orion-xor" or "marvell,armada-380-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;
};
};
