  After a discussion about removing VLYNQ support from the Kernel, it was
concluded that its only user, the AR7 platform can go [1]. Even OpenWRT
has removed support because these devices are "stuck with 3.18" [2].

Hi Thomas,

most people involved in this series think that it will be best to take
the whole series via the MIPS tree. Do you agree?

Happy hacking,

the series doesn't apply to mips-next, can you rebase it top of it ?

Thomas.

nevermind, I've did it by hand, but using --irreversible-delete isn't very
maintainer friendly as patches won't apply and I need to do the git rm
manually.

I am really sorry, this slipped through the cracks :( Thanks for doing
it and feel free to ping me again and again next time!
