SubjectRe: [PATCH 00/16] move at91 and avr32 to the PWM framework, remove obsolete drivers

I am fine with the whole series. For the AT91 specific bits, you can add my:

Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com>

It is a very nice cleanup and I can take the series with me in the AT91
git tree (likely the at91-3.16-cleanup or at91-3.16-drivers branch) if
everybody agree.
