According to https://wikidevi.com/wiki/Linksys_EA4500 there are multiple versions
of this device, and at least EA4500v3 is completely incompatible with the version
in this patch. Should we add "linksys,ea4500v1" as a compatible string to identify
this better?

Right. I'll send v2 after getting some more comments.

Hi Luka

This part should probably be a patch of its own, sent to the DT
maintainers.

Please use stdout-path = &uart0; You can also put the baud rate etc on
the end.

Is there a hole here?

Why fix the speed? Are they connected to a switch?

The same device was sold as the ea4200v2 as well. Please use the  
engineering name "viper" instead, as discussed at  
http://lists.infradead.org/pipermail/linux-arm-kernel/2015-January/319590.html

Although Linksys is a subsidiary of Belkin, I think linksys should stay  
Linksys here ;)

Please use the factory partitions instead.

Not sure, as "v1" is never marked on the box/boards, and for this reason  
as far as I remember, we've never marked "v1" on any upstream code (unlike  
vX).
