[PATCH] ARM: OMAP2+: enable EHCI by default

[PATCH] ARM: OMAP2+: enable EHCI by default

[Thomas Pedersen]

This is needed for the pandaboard (ES) kernel to detect
the ethernet device during boot. Useful for NFS root etc.

Thanks for the patch, just to clarify why we have not been able
to apply this is EHCI blocks deeper PM states for at least omap3
currently. And this means the PM related tests won't run properly
out of the box..

Roger has been working to get EHCI working properly with PM,
and the recent interrupts-extended binding and the addition of
wake-up interrupts to pinctrl-single.c should allow us to do that
soon. Maybe Roger can summarize what else might still be missing?

Regards,

Tony
