   4 Subject: [PATCH] staging: mt7621-pci: use only two phys from device tree
   5
   6 In order to align work with the mt7621-pci-phy part of
   7 the driver and device tree which is now using only two
   8 real phys one of them dual ported properly parse the
   9 device tree and don't call phy initialization for the
  10 slot 1 because is being taking into account when the
  11 phy for the slot 0 is instantiated.
