Hmm actually looks like we can actually remove all the omap2+
support as we no longer have any users for this one. I think I
already converted the last one to matrix-keypad a while back.

Yeah good point, I'll update that and remove the omap2+ support
for this driver.

Sounds like no need for that, as we're no longer using this for
omap2+..

Heh yeah that nice way to do it :)

Yes you're right. Will send an updated one tomorrow.
