+description: |
+ Each FMan has several MACs, each implementing an Ethernet interface. Earlier
+ versions of FMan used the Datapath Three Speed Ethernet Controller (dTSEC) for
+ 10/100/1000 MBit/s speeds, and the 10-Gigabit Ethernet Media Access Controller
+ (10GEC) for 10 Gbit/s speeds. Later versions of FMan use the Multirate
+ Ethernet Media Access Controller (mEMAC) to handle all speeds.

FMan dTSEC/XGEC/mEMAC Node
-DESCRIPTION
-
-mEMAC/dTSEC/XGEC are the Ethernet network interfaces
-
-PROPERTIES
-
-- compatible
- Usage: required
- Value type: <stringlist>
- Definition: A standard property.
- Must include one of the following:
- - "fsl,fman-dtsec" for dTSEC MAC
- - "fsl,fman-xgec" for XGEC MAC
- - "fsl,fman-memac" for mEMAC MAC
-
-- cell-index
- Usage: required
- Value type: <u32>
- Definition: Specifies the MAC id.
-
- The cell-index value may be used by the FMan or the SoC, to
- identify the MAC unit in the FMan (or SoC) memory map.
- In the tables below there's a description of the cell-index
- use, there are two tables, one describes the use of cell-index
- by the FMan, the second describes the use by the SoC:
