[PATCH net,v3 0/2] Update MT7629 to support PHYLINK API

[MarkLee]

This patch set has two goals :
	1. Fix mt7629 GMII mode issue after apply mediatek
	   PHYLINK support patch.
	2. Update mt7629 dts to reflect the latest dt-binding
	   with PHYLINK support.

[PATCH net, v3 1/2] net: ethernet: mediatek: Fix MT7629 missing GMII mode support

[MarkLee]

In the original design, mtk_phy_connect function will set ge_mode=1
if phy-mode is GMII(PHY_INTERFACE_MODE_GMII) and then set the correct
ge_mode to ETHSYS_SYSCFG0 register. This logic was broken after apply  
mediatek PHYLINK patch(Fixes tag), the new mtk_mac_config function will
not set ge_mode=1 for GMII mode hence the final ETHSYS_SYSCFG0 setting 
will be incorrect for mt7629 GMII mode. This patch add the missing logic
back to fix it.

[PATCH net, v3 2/2] arm: dts: mediatek: Update mt7629 dts to reflect the latest dt-binding

[MarkLee]

* Removes mediatek,physpeed property from dtsi that is useless in PHYLINK
* Use the fixed-link property speed = <2500> to set the phy in 2.5Gbit.
* Set gmac1 to gmii mode that connect to a internal gphy

v1->v2:
* SGMII port only support BASE-X at 2.5Gbit.
