Sure, it was merely an illustration. I figured you must have some code
since you've been testing it on AACI and whatnot. I'm currently in the
countryside, I plan to pick this up when I get back to the office (where
the PB11MPCore is) in mid-august.

If you have some platform data + mux code that fits with your latest
patches to the PL08x driver, then please poste to LAKML and I'll have
them tested ASAP.

Yours,
Linus Walleij
