Subject: [PATCH] arm64: dts: ls104x: disable ALDPS for the RTL8211F PHYs
ALDPS is enabled by default for the RTL8211F RGMII PHYs starting with
commit 66e22932eb79 ("net: phy: realtek: enable ALDPS to save power for
RTL8211F"). This enablement causes auto negotiation issues when
disconnecting and reconnecting the PHY successively.
According to the PHY data sheet, this feature is disabled by default. Add
the "rtl821x,aldps-disable" device tree property to mark this under the
affected nodes.
