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. + +Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> +--- + arch/arm64/boot/dts/freescale/fsl-ls1028a-rdb.dts | 4 ++++ + 1 file changed, 4 insertions(+) + +--- a/arch/arm64/boot/dts/freescale/fsl-ls1028a-rdb.dts ++++ b/arch/arm64/boot/dts/freescale/fsl-ls1028a-rdb.dts +@@ -236,21 +236,25 @@ + &switch_port0 { + phy-handle = <&qsgmii_phy1>; + phy-connection-type = "qsgmii"; ++ managed = "in-band-status"; + }; + + &switch_port1 { + phy-handle = <&qsgmii_phy2>; + phy-connection-type = "qsgmii"; ++ managed = "in-band-status"; + }; + + &switch_port2 { + phy-handle = <&qsgmii_phy3>; + phy-connection-type = "qsgmii"; ++ managed = "in-band-status"; + }; + + &switch_port3 { + phy-handle = <&qsgmii_phy4>; + phy-connection-type = "qsgmii"; ++ managed = "in-band-status"; + }; + + &sai4 { |
