Merge tag 'omap-for-v4.2/omap1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

Merge fixed up omap1 sparse irq support for v4.2 from Tony Lindgren:

Add support for CONFIG_SPARSE_IRQ for omap1. This takes us a bit closer
to making omap1 support multiarch. After this series we still need to
make omap1 use the common clock framework and fix up the drivers to not
rely on includes from mach and plat directories.

Note that this branch depends on a GPIO driver fix in v4.1-rc3
d2d05c65 ("gpio: omap: Fix regression for MPUIO interrupts").
