Ok, I've dug through the docs on the 460EPx (the CPU I'm using), and
I'd like some confirmation of the following:
* The EMAC hardware itself internally has its own dedicated
MDIO/MDClk lines, driven by the STACR register.
Yes, though

I'm also curious about the intent of the mdio_instance pointer (IE:
the mdio-device property). Is that used when all the PHY devices
are attached to the MDIO bus of only one of the (multiple) emac
devices?
It's common

Just a heads up Kyle; there are changes queued in the netdev tree
which add OF helpers for MDIO bus drivers and MAC drivers. See here:
Ok, I've made some progress in the port, but right now I'm trying to
puzzle out what the gpcs bits in the code are. From the few
publicly available docs and some mailing list posts, the gpcs address
appears to be some kind of integrated virtual PHY used when 460GT-ish
chips are

Well... GPCS is indeed some kind of internal PHY if you like but it's
not MDIO controlled and I don't really see a need to move it to the
phylib as it's so specific to the NIC itself. But if you think it

Hmm, yeah, I'd be interested to see those. There's enough similar

Hello,
I'm currently fiddling with a custom embedded prototype board using
the ibm_newemac driver with some currently-unsupported PHYs. Those
PHYs *are* supported by phylib, but the emac driver seems to have its
own
