Hi Linus,

thanks for the work converting Gemini to DT.

AFAICR
This is a dual GMAC !

They are two different base address for each GMAC and one shared
base address for both of them.
This is all in one address space which remaps the driver.

And to make it worse two interrupt lines, one of them is also shared.

Any ideas to "convert" this into DT ??
Because I think it's impossible to split both GMAC interfaces ??
