Hi MarkLee,
Quoting MarkLee <Mark-MC.Lee@xxxxxxxxxxxx>:
* Removes mediatek,physpeed property from dtsi that is useless in PHYLINK
* Set gmac0 to fixed-link sgmii 2.5Gbit mode
* Set gmac1 to gmii mode that connect to a internal gphy

2.17.1
Does MT7629 soc has the same SGMII IP block as on the MT7622?
If that is the case then phy-mode should set to "2500base-x".
See discussion about the MT7622 [1] and dts of
mt7622-bananapi-bpi-r64.dts[2][3]
Note the code only set the phy in overclock mode if phymode =
2500base-x and the
link is a fixed-link, see [4].
Alsp the current code doesn't support sgmii so well. Sgmii at 2.5Gbit is not
supported at all.
Greats,
René
