Rob Herring 4da722ca19 dt-bindings: Remove "status" from examples
Pretty much any node can have a status property, so it doesn't need to
be in examples.

Converted with the following command and removed examples with SoC and
board specific splits:

git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'

* 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>;
};
};
