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>
+ fsl,corenet-cf - CoreNet coherency fabric version 1
+ fsl,corenetX-cf - CoreNet coherency fabric version X
+
+- reg : <prop-encoded-array>
+ A standard property. Specifies the pshysical address and
+ length of the CoreNet coherency fabric memory space.
+
+- interrupts : <prop-encoded-array>
+ Interrupt mapping for CCF error interrupt.
+
+- fsl,ccf-num-csdids: <u32>
+ Specifies the number of Coherency Subdomain ID Port Mapping
+ Registers that are supported by the CCF.
+
+- fsl,ccf-num-snoopids: <u32>
+ Specifies the number of Snoop ID Port Mapping Registers that
+ are supported by CCF.
+
+Example:
+
+ corenet-cf@18000 {
+ compatible = "fsl,corenet2-cf";
+ reg = <0x18000 0x1000>;
+ interrupts = <16 2 1 31>;
+ fsl,ccf-num-csdids = <32>;
+ fsl,ccf-num-snoopids = <32>;
+ };
