Hmm, strange.
I've been testing this without any significant patches, like PWM, CCF or DT support, just everything from the branch I pointed to and some board- specific patches to help in debugging.
Anyway, this is the exact branch I've been using:
git://github.com/tom3q/linux.git v3.12-pl080-devel
