[PATCH v2] powerpc/fsl: Added binding for Freescale CoreNet coherency fabric (CCF)

[Diana Craciun]

From: Diana Craciun <Diana.Craciun at freescale.com>

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
+
+- reg : <prop-encoded-array>
+		A standard property. Represents the CCF registers.
+
+- 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 at 18000 {
+		compatible = "fsl,corenet2-cf", "fsl,corenet-cf";
+		reg = <0x18000 0x1000>;
+		interrupts = <16 2 1 31>;
+		fsl,ccf-num-csdids = <32>;
+		fsl,ccf-num-snoopids = <32>;
+	};
