5*4882a593SmuzhiyunRequired properties:
6*4882a593Smuzhiyun
7*4882a593Smuzhiyun- compatible: the possible values are:
8*4882a593Smuzhiyun
9*4882a593Smuzhiyun * "marvell,coherency-fabric", to be used for the coherency fabric of
10*4882a593Smuzhiyun   the Armada 370 and Armada XP.
11*4882a593Smuzhiyun
12*4882a593Smuzhiyun * "marvell,armada-375-coherency-fabric", for the Armada 375 coherency
13*4882a593Smuzhiyun   fabric.
14*4882a593Smuzhiyun
15*4882a593Smuzhiyun * "marvell,armada-380-coherency-fabric", for the Armada 38x coherency
16*4882a593Smuzhiyun   fabric.
17*4882a593Smuzhiyun
18*4882a593Smuzhiyun- reg: Should contain coherency fabric registers location and
19*4882a593Smuzhiyun  length.
20*4882a593Smuzhiyun
21*4882a593Smuzhiyun * For "marvell,coherency-fabric", the first pair for the coherency
22*4882a593Smuzhiyun   fabric registers, second pair for the per-CPU fabric registers.
23*4882a593Smuzhiyun
24*4882a593Smuzhiyun * For "marvell,armada-375-coherency-fabric", only one pair is needed
25*4882a593Smuzhiyun   for the per-CPU fabric registers.
26*4882a593Smuzhiyun
27*4882a593Smuzhiyun * For "marvell,armada-380-coherency-fabric", only one pair is needed
28*4882a593Smuzhiyun   for the per-CPU fabric registers.
