This +is considered a quirk so the phylink switches the interface to +2500base-x as well. + +However, after power-cycling the uDPU device, network interface/SFP module +will not work correctly until the module is re-seated. This patch +resolves this issue by forcing the interface to be brought up in +2500base-x mode by default. + +Signed-off-by: Jakov Petrina <jakov.petrina@sartura.hr> +Signed-off-by: Vladimir Vid <vladimir.vid@sartura.hr> +Cc: Luka Perkov <luka.perkov@sartura.hr> + +--- a/arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts ++++ b/arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts +@@ -162,7 +162,7 @@ + }; + + ð0 { +- phy-mode = "sgmii"; ++ phy-mode = "2500base-x"; + status = "okay"; + managed = "in-band-status"; + phys = <&comphy1 0>; +@@ -170,7 +170,7 @@ + }; + + ð1 { +- phy-mode = "sgmii"; ++ phy-mode = "2500base-x"; + status = "okay"; + managed = "in-band-status"; + phys = <&comphy0 1>; |
