From f63463591b9f664353b4375f5dfdba980c7bdc07 Mon Sep 17 00:00:00 2001 From: Daniel Gimpelevich Date: Wed, 1 Aug 2018 07:51:47 -0700 Subject: [PATCH] ramips: fix gigabit switch PHY access on MDIO When PHY's are defined on the MDIO bus in the DTS, gigabit support was being masked out for no apparent reason, pegging all such ports to 10/100. If gigabit support must be disabled for some reason, there should be a "max-speed" property in the DTS.
