Aquantia PHY in OCSGMII mode?

[Alexander Wilhelm]

Hello devs,

I'm fairly new to Ethernet PHY drivers and would appreciate your help. I'm
working with the Aquantia AQR115 PHY. The existing driver already supports the
AQR115C, so I reused that code for the AQR115, assuming minimal differences. My
goal is to enable 2.5G link speed. The PHY supports OCSGMII mode, which seems to
be non-standard.

* Is it possible to use this mode with the current driver?
* If yes, what would be the correct DTS entry?
* If not, I’d be willing to implement support. Could you suggest a good starting point?

Any hints or guidance would be greatly appreciated.


Best regards
