From 34a568a244bef287de2ff9a30c2ed369fb64dbfd Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Mon, 9 Mar 2020 13:32:40 +0100 Subject: [PATCH] net: sgi: ioc3-eth: Remove phy workaround Commit a8d0f11ee50d ("MIPS: SGI-IP27: Enable ethernet phy on second Origin 200 module") fixes the root cause of not detected PHYs. Therefore the workaround can go away now. Signed-off-by: Thomas Bogendoerfer Signed-off-by: David S.
