   1 * Freescale Management Complex
   2
   3 The Freescale Management Complex (fsl-mc) is a hardware resource
   4 manager that manages specialized hardware objects used in
   5 network-oriented packet processing applications. After the fsl-mc
   6 block is enabled, pools of hardware resources are available, such as
   7 queues, buffer pools, I/O interfaces. These resources are building
   8 blocks that can be used to create functional hardware objects/devices
   9 such as network interfaces, crypto accelerator instances, L2 switches,
  10 etc.

  12 Required properties:
  13
  14     - compatible
  15         Value type: <string>
  16         Definition: Must be "fsl,qoriq-mc".  A Freescale Management Complex
  17                     compatible with this binding must have Block Revision
  18                     Registers BRR1 and BRR2 at offset 0x0BF8 and 0x0BFC in
  19                     the MC control register region.
  20
  21     - reg
  22         Value type: <prop-encoded-array>
  23         Definition: A standard property.  Specifies one or two regions
  24                     defining the MC's registers:
  25
  26                        -the first region is the command portal for the
  27                         this machine and must always be present
  28
  29                        -the second region is the MC control registers. This
  30                         region may not be present in some scenarios, such
  31                         as in the device tree presented to a virtual machine.

  33 Example:
  34
  35         fsl_mc: fsl-mc@80c000000 {
  36                 compatible = "fsl,qoriq-mc";
  37                 reg = <0x00000008 0x0c000000 0 0x40>,    /* MC portal base */
  38                       <0x00000000 0x08340000 0 0x40000>; /* MC control reg */
  39         };
