Hello,

> Add driver to support the Maxlinear GPY115, GPY211, GPY212, GPY215,
> GPY241, GPY245 PHYs.
to me this seems like an evolution of the Lantiq XWAY PHYs for which
we already have a driver: intel-xway.c.
Intel took over Lantiq some years ago and last year MaxLinear then
took over what was formerly Lantiq from Intel.

>From what I can tell right away: the interrupt handling still seems
to be the same. Also the GPHY firmware version register also was there
on older SoCs (with two or more GPHYs embedded into the SoC). SGMII
support is new. And I am not sure about Wake-on-LAN.

Have you considered adding support for these new PHYs to intel-xway.c?



Best regards,
Martin
