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