Instead of using cpu_is_omap..() macros in the device driver we
rely on information provided in the platform data.

The only information we need is whether the USB Host module has
a single ULPI bypass control bit for all ports or individual bypass
control bits for each port. OMAP3 REV2.1 and earlier have the former.

I'd like to apply this patch as a fix so I can finally nuke plat/cpu.h
for omaps by -rc1 before more drivers start using it again.

That is assuming nobody else is planning on merging this series for
v3.8 presumably. Want to ack this one?

Regards,

Tony

This should go into 3.9, yes.

Looks fine to me:

OK looks like you have all the necessary acks except for one
clock change. I replied to that one.

Thanks, I'll queue that one and then after -rc1 hopefully
you have all the necessary acks to queue this one via your
mfd tree.

Regards,

Tony
