From: Sean Wang <sean.wang@mediatek.com> adds PHY-mode "trgmii" as an extension for the operation mode of the PHY interface, TRGMII can be compatible with RGMII, so the extended mode doesn't really have effects on the target MAC and PHY, is used as the indication if the current MAC is connected to an internal switch or external PHY respectively by the given configuration on the board and then to perform the corresponding setup on TRGMII hardware module.
Based on my googling, it seems like Turbo RGMII is a Mediatek-specific thing for now, but this could become standard and used by other vendors at some point, so I would be inclined to just extend the phy-mode property to support trgmii as another interface type. If you do so, do you also mind proposing an update to the Device Tree specification: https://www.devicetree.org/specifications/ Thanks! -- Florian
