maintainers:

description:
Due to the fact that the FMan is an aggregation of sub-engines (ports, MACs,
etc.) the FMan node will have child nodes for each of them.
properties:
compatible:
enum:
- fsl,fman
description:
FMan version can be determined via FM_IP_REV_1 register in the
FMan block. The offset is 0xc4 from the beginning of the
Frame Processing Manager memory map (0xc3000 from the
beginning of the FMan node).
cell-index:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Specifies the index of the FMan unit.
The cell-index value may be used by the SoC, to identify the
FMan unit in the SoC memory map. In the table below,
there's a description of the cell-index use in each SoC:
- P1023:
register[bit] FMan unit cell-index
============================================================
DEVDISR[1] 1 0
- P2041, P3041, P4080 P5020, P5040:
register[bit] FMan unit cell-index
============================================================
DCFG_DEVDISR2[6] 1 0
DCFG_DEVDISR2[14] 2 1
(Second FM available only in P4080 and P5040)
- B4860, T1040, T2080, T4240:
register[bit] FMan unit cell-index
============================================================
DCFG_CCSR_DEVDISR2[24] 1 0
DCFG_CCSR_DEVDISR2[25] 2 1
(Second FM available only in T4240)
DEVDISR, DCFG_DEVDISR2 and DCFG_CCSR_DEVDISR2 are located in
the specific SoC "Device Configuration/Pin Control" Memory
Map.
