Kernel-3.10.0-957.el7_mv-xor

• 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;
};

};
