+* Freescale Management Complex
+
+The Freescale Management Complex (fsl-mc) is a hardware resource
+manager that manages specialized hardware objects used in
+network-oriented packet processing applications. After the fsl-mc
+block is enabled, pools of hardware resources are available, such as
+queues, buffer pools, I/O interfaces. These resources are building
+blocks that can be used to create functional hardware objects/devices
+such as network interfaces, crypto accelerator instances, L2 switches,
+etc.
+
+Required properties:
+
+ - compatible
+ Value type: <string>
+ Definition: Must be "fsl,qoriq-mc". A Freescale Management Complex
+ compatible with this binding must have Block Revision
+ Registers BRR1 and BRR2 at offset 0x0BF8 and 0x0BFC in
+ the MC control register region.
+
+ - reg
+ Value type: <prop-encoded-array>
+ Definition: A standard property. Specifies one or two regions
+ defining the MC's registers:
+
+ -the first region is the command portal for the
+ this machine and must always be present
+
+ -the second region is the MC control registers. This
+ region may not be present in some scenarios, such
+ as in the device tree presented to a virtual machine.
+
+Example:
+
+ fsl_mc: fsl-mc@80c000000 {
+ compatible = "fsl,qoriq-mc";
+ reg = <0x00000008 0x0c000000 0 0x40>, /* MC portal base */
+ <0x00000000 0x08340000 0 0x40000>; /* MC control reg */
+ };
