From 57c0539d99fed2252364b431de004f9110ac3d3f Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 6 Dec 2019 13:59:05 +0200 Subject: [PATCH] arm64: dts: ls1028a-rdb: Enable SGMII AN for the QSGMII switch ports This enables monitoring of link status and AN. It should also physically enable SGMII AN with the VSC8514 PHY, but in practice that is still hardcoded as "on" in the PHY driver, at the moment. So since Felix actually disables SGMII AN when this DT property is absent, this would result in an in-band AN mismatch between the MAC and the PHY. So this property is required for the moment for this MAC/PHY combination.
