   4 Subject: [PATCH 1/2] drivers: net: mediatek: register of_platform for every
   5  port
   6
   7 Currently the nvmem framework require the devicenode to be registred on
   8 the of_platform or of_get_mac_address fail to get the macaddress if
   9 defined using an nvmem cell. Fix this by registrering these special node
  10 so they can be found by of_find_device_by_node.
