[PATCH net-next 1/3] net: ethernet: mediatek: add extension of phy-mode for TRGMII

From: Sean Wang 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

[PATCH net-next 0/3] add support for RGMII on GMAC0 through TRGMII hardware module

From: Sean Wang By default, GMAC0 is connected to built-in switch called MT7530 through the proprietary interface called Turbo RGMII (TRGMII). TRGMII also supports well for RGMII as generic external PHY uses but requires some slight changes to the setup of TRGMII and
