These two patches incorporate changes to OMAP1 and OMAP2 platforms
board files whereby older references to OMAP_GPIO_IRQ macro are
now replaced with gpio_to_irq(), thereby getting rid of static
irq references.

Can you please tell the exact two commits causing this
breakage?
Well, this is the GPIO DT + SPARSE_IRQ series I have done. It appears
that the boards I have were already using properly gpio_to_irq() and
thus were working fine with this series.
But this is unfortunately not the case of most OMAP2 and 3 legacy boards
that were still using an old OMAP way of converting GPIO to IRQ and were
never modified to take advantage of the gpiolib stuff.
So if these patches are apply before the GPIO DT + SPARSE_IRQ series,
there will be no breakage at all.
All the cleanup we have never done before will hurt us at some point
when we will start using more extensively newer fmwk (DT, sparse_irq,
dmaengine...). It was not done on purpose, but this GPIO series
highlighted this remaining static broken mapping inside OMAP boards.
I'm baffled how despite all the effort for previnting
issues like this this still happen. These all seem valid
fixes and clean up things, but how come this was not seen
earlier?
Maybe because there are much more boards inside mach-omap2 directory
than inside my cubicle... :-(
Regards,
Benoit
