From 2368f7cb78464a040ef014ca8652262dbcfc7fc7 Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Fri, 19 Jan 2018 20:19:06 +0100 Subject: [PATCH] lantiq: kernel 4.14: autoselect matching vr9 rev 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.
