      1Hisilicon Network Subsystem NIC controller
      2
      3Required properties:
      4- compatible: "hisilicon,hns-nic-v1" or "hisilicon,hns-nic-v2".
      5  "hisilicon,hns-nic-v1" is for hip05.
      6  "hisilicon,hns-nic-v2" is for Hi1610 and Hi1612.
      7- ae-handle: accelerator engine handle for hns,
      8  specifies a reference to the associating hardware driver node.
      9  see Documentation/devicetree/bindings/net/hisilicon-hns-dsaf.txt
     10- port-id: is the index of port provided by DSAF (the accelerator). DSAF can
     11  connect to 8 PHYs. Port 0 to 1 are both used for administration purpose. They
     12  are called debug ports.
     13
     14  The remaining 6 PHYs are taken according to the mode of DSAF.
     15
     16  In NIC mode of DSAF, all 6 PHYs are taken as ethernet ports to the CPU. The
     17  port-id can be 2 to 7. Here is the diagram:
     18            +-----+---------------+
     19            |            CPU      |
     20            +-+-+-+---+-+-+-+-+-+-+

     24             (0,1)       (2-7)
     25
     26  In Switch mode of DSAF, all 6 PHYs are taken as physical ports connect to a
     27  LAN Switch while the CPU side assume itself have one single NIC connect to
     28  this switch. In this case, the port-id will be 2 only.

     39  This attribute is remained for compatible purpose. It is not recommended to
     40  use it in new code.
     41
     42- port-idx-in-ae: is the index of port provided by AE.
     43  In NIC mode of DSAF, all 6 PHYs of service DSAF are taken as ethernet ports
     44  to the CPU. The port-idx-in-ae can be 0 to 5. Here is the diagram:
     45            +-----+---------------+
     46            |            CPU      |

     51           (0)   (0)     (0-5)
     52
     53  In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical
     54  ports connected to a LAN Switch while the CPU side assume itself have one
     55  single NIC connected to this switch. In this case, the port-idx-in-ae
     56  will be 0 only.
