5Required properties:
6
7- compatible: the possible values are:
8
9 * "marvell,coherency-fabric", to be used for the coherency fabric of
10   the Armada 370 and Armada XP.
11
12 * "marvell,armada-375-coherency-fabric", for the Armada 375 coherency
13   fabric.
14
15 * "marvell,armada-380-coherency-fabric", for the Armada 38x coherency
16   fabric.
17
18- reg: Should contain coherency fabric registers location and
19  length.
20
21 * For "marvell,coherency-fabric", the first pair for the coherency
22   fabric registers, second pair for the per-CPU fabric registers.
23
24 * For "marvell,armada-375-coherency-fabric", only one pair is needed
25   for the per-CPU fabric registers.
26
27 * For "marvell,armada-380-coherency-fabric", only one pair is needed
28   for the per-CPU fabric registers.

30Optional properties:
31
32- broken-idle: boolean to set when the Idle mode is not supported by the
33  hardware.
