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.
