David Bauer 3444638a05 ar71xx: fix QCA955X SGMII link loss ... The QCA955X is affected by a hardware bug which causes link-loss of the SGMII link between SoC and PHY. This happens on change of link-state or speed. It is not really known what causes this bug. It definitely occurs when using a AR8033 Gigabit Ethernet PHY. Qualcomm solves this Bug in a similar fashion. We need to apply the fix on a per-device base via platform-data as performing the fixup work will break connectivity in case the SGMII interface is connected to a Switch. This bug was first proposed to be fixed by Sven Eckelmann in 2016. https://patchwork.ozlabs.org/patch/604782/ Based-on-patch-by: Sven Eckelmann <sven.eckelmann@open-mesh.com> Signed-off-by: David Bauer <mail@david-bauer.net> (cherry picked from commit f4f99ec973)		2018-09-03 23:04:46 +02:00
