   1 * Marvell XOR engines
   2
   3 Required properties:
   4 - compatible: Should be one of the following:
   5   - "marvell,orion-xor"
   6   - "marvell,armada-380-xor"
   7   - "marvell,armada-3700-xor".
   8 - reg: Should contain registers location and length (two sets)
   9     the first set is the low registers, the second set the high
  10     registers for the XOR engine.
  11 - clocks: pointer to the reference clock
  12
  13 The DT node must also contains sub-nodes for each XOR channel that the
  14 XOR engine has. Those sub-nodes have the following required
  15 properties:
  16 - interrupts: interrupt of the XOR channel
  17
  18 The sub-nodes used to contain one or several of the following
  19 properties, but they are now deprecated:
  20 - dmacap,memcpy to indicate that the XOR channel is capable of memcpy operations
  21 - dmacap,memset to indicate that the XOR channel is capable of memset operations
  22 - dmacap,xor to indicate that the XOR channel is capable of xor operations
  23 - dmacap,interrupt to indicate that the XOR channel is capable of
  24   generating interrupts

  26 Example:
  27
  28 xor@d0060900 {
  29         compatible = "marvell,orion-xor";
  30         reg = <0xd0060900 0x100
  31                0xd0060b00 0x100>;
  32         clocks = <&coreclk 0>;
  33         status = "okay";
  34
  35         xor00 {
  36               interrupts = <51>;
  37         };
  38         xor01 {
  39               interrupts = <52>;
  40         };
  41 };
