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: + 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: + 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.
