12description:
13 Due to the fact that the FMan is an aggregation of sub-engines (ports, MACs,
14 etc.) the FMan node will have child nodes for each of them.

17 compatible:
18 enum:
19 - fsl,fman
20 description:
21 FMan version can be determined via FM_IP_REV_1 register in the
22 FMan block. The offset is 0xc4 from the beginning of the
23 Frame Processing Manager memory map (0xc3000 from the
24 beginning of the FMan node).

26 cell-index:
27 $ref: /schemas/types.yaml#/definitions/uint32
28 description: |
29 Specifies the index of the FMan unit.

31 The cell-index value may be used by the SoC, to identify the
32 FMan unit in the SoC memory map. In the table below,
33 there's a description of the cell-index use in each SoC:
34
35 - P1023:
36 register[bit] FMan unit cell-index
37 ============================================================
38 DEVDISR[1] 1 0

43 DCFG_DEVDISR2[6] 1 0
44 DCFG_DEVDISR2[14] 2 1
45 (Second FM available only in P4080 and P5040)

47 - B4860, T1040, T2080, T4240:
48 register[bit] FMan unit cell-index

51 DCFG_CCSR_DEVDISR2[25] 2 1
52 (Second FM available only in T4240)
53
54 DEVDISR, DCFG_DEVDISR2 and DCFG_CCSR_DEVDISR2 are located in
55 the specific SoC "Device Configuration/Pin Control" Memory
56 Map.
