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:
