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. | |
| 11 | ||
| 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. | |
| 32 | ||
| 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 | }; | |
