   4 Subject: [PATCH] MIPS: lantiq: autoselect matching vr9 rev gphy firmware
   5
   6 Add a custom xrx200 ethernet phy compatible to load the firmware matching
   7 the vr9 revision without specifing an expected revision.
   8
   9 We have quite a few boards in the tree were later produced ones are using
  10 a more recent vr9. It is impossible to distinguish which revision of the
  11 vr9 is used without opening the case and removing a heatsink for some of
  12 them.
