I am willing to do the these thing

1)
in the next version, I will extend rgmii mode as
another interface type as PHY_INTERFACE_MODE_TRGMII
defined in linux/phy.h instead of extension only inside
the current driver. This change also helps to save some code.

2)
I send another separate patch for updating the Device Tree
specification about TRGMII adding description

are these all okay for you?
