Changes since v1:
* kept uapi define for for serial port type
* added acks
Still valid cover letter from v1:
When trying to get rid of the obsolete VLYNQ bus, Jonas and Florian
pointed out that its only user, the AR7 platform can probaly go entirely
[1]. This series does exactly that. Even OpenWRT has removed support
because these devices are "stuck with 3.18" [2].
It removes the drivers first, because watchdog and network include
platform specific headers. Once the drivers are gone, we remove the
platform. The patches are based on 6.6-rc2 and created with
"--irreversible-delete" to save some space.
My suggestion is that everything is merged via the MIPS tree in one go,
so we don't have broken drivers because of missing platform headers. But
maybe there are reasons for a two-cycle removal with the drivers first
and the platform later?
Looking forward to comments.
Happy hacking,
Wolfram

AR7 is going to be removed from the Kernel, so remove its type
definition from 8250 code. As with previous removals, I checked with
Debian Code Search that 'PORT_AR7' is not used in userspace.

applied to mips-next, minus patch 5, which is already applied to net-next.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
