Hi,

Yes, since we are so late in the -rc cycle and OMAP1 is currently
broken I agree that the only sensible solution is to revert the patch
for now.

I just wanted to point out the issue that keeping the OMAP GPIO driver
using legacy mapping domain represents a blocker to have GPIO-IRQ
working with Device Tree for OMAP2+

Thanks a lot and best regards,
Javier
