7 title: Freescale Frame Manager Port Device
10   - Frank Li <Frank.Li@nxp.com>
13   The Frame Manager (FMan) supports several types of hardware ports:
14     Ethernet receiver (RX)
21       - fsl,fman-v2-port-oh
22       - fsl,fman-v2-port-rx
23       - fsl,fman-v2-port-tx
24       - fsl,fman-v3-port-oh
25       - fsl,fman-v3-port-rx
26       - fsl,fman-v3-port-tx
28   cell-index:
31       Specifies the hardware port id.
32       Each hardware port on the FMan has its own hardware PortID.
33       Super set of all hardware Port IDs available at FMan Reference
34       Manual under "FMan Hardware Ports in Freescale Devices" table.
36       Each hardware port is assigned a 4KB, port-specific page in
37       the FMan hardware port memory region (which is part of the
38       FMan memory map). The first 4 KB in the FMan hardware ports
42       The page of a specific port is determined by the cell-index.

52       If this property exists, the port is s 10G port.
