The CoreNet coherency fabric is a fabric-oriented, conectivity
infrastructure that enables the implementation of coherent, multicore
systems. The CCF acts as a central interconnect for cores,
platform-level caches, memory subsystem, peripheral devices and I/O host
bridges in the system.

+Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding
+
+DESCRIPTION
+
+The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
+that enables the implementation of coherent, multicore systems.
+
+Required properties:
+
+- compatible : <string>
+		Must include "fsl,corenetX-cf", "fsl,corenet-cf" - CoreNet coherency 
+		fabric version X

Can we make this ‘fsl,corenet-vX-cf’.

corenet-v1-cf/corenet-v2-cf looks nicer than corenet1-cf/corenet2-cf

How important is this?  We've already got corenet2-cf in SDK device
trees -- and while I know that's not binding on upstream in any way,
it's purely a cosmetic change.  Even if you disregard the SDK, is this
really worth going back and amending several pending patches over
(including a driver that I was waiting for this binding to settle before
sending)?  

FWIW, we have other instances of "deviceN", such as "fsl,etsec2",
"fsl,cpm2-<foo>","fsl,usb2-<foo>", and "fsl,elo3-dma".  We also call it
"corenet2" in U-Boot a lot.

If we must change it, I'd prefer "fsl,corenet-cf-vX.0".
