Kernel-4.18.0-80.el8_mv-xor

  • Marvell XOR engines

Required properties:

  • compatible: Should be one of the following:
    • “marvell,orion-xor”
    • “marvell,armada-380-xor”
    • “marvell,armada-3700-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

The sub-nodes used to contain one or several of the following
properties, but they are now deprecated:

  • 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
  • dmacap,interrupt to indicate that the XOR channel is capable of
    generating interrupts

Example:

xor@d0060900 {
compatible = “marvell,orion-xor”;
reg = <0xd0060900 0x100
0xd0060b00 0x100>;
clocks = <&coreclk 0>;

xor00 {
      interrupts = <51>;
};
xor01 {
      interrupts = <52>;
};

};
