1 * Freescale Management Complex
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,
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.
22 Value type: <prop-encoded-array>
23 Definition: A standard property. Specifies one or two regions
24 defining the MC's registers:
26 -the first region is the command portal for the
27 this machine and must always be present
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.
35 Definition: Must be present and point to the MSI controller node
36 handling message interrupts for the MC.
39 Value type: <prop-encoded-array>
40 Definition: A standard property. Defines the mapping between the child
41 MC address space and the parent system address space.
43 The MC address space is defined by 3 components:
44 <region type> <offset hi> <offset lo>
46 Valid values for region type are
52 Definition: Must be 3. (see definition in 'ranges' property)
56 Definition: Must be 1.
60 The fsl-mc node may optionally have dpmac sub-nodes that describe
61 the relationship between the Ethernet MACs which belong to the MC
62 and the Ethernet PHYs on the system board.
64 The dpmac nodes must be under a node named "dpmacs" which contains
65 the following properties:
69 Definition: Must be present if dpmac sub-nodes are defined and must
74 Definition: Must be present if dpmac sub-nodes are defined and must
77 These nodes must have the following properties:
81 Definition: Must be "fsl,qoriq-mc-dpmac".
84 Value type: <prop-encoded-array>
85 Definition: Specifies the id of the dpmac.
89 Definition: Specifies the phandle to the PHY device node associated
