Merge tag 'omap-for-v4.2/wakeirq-drivers-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/late
Merge "omap generic wakeirq for v4.2 merge window" from Tony Lindgren:
Omap driver changes for v4.2 to switch drivers over to Linux generic
wake IRQ events for omap_hsmmc, 8250_omap and omap-serial
drivers.
The generic wake IRQs also fix issues that these drivers potentially
have with IRQ re-entrancy at least for serial-omap.
Note that because of dependencies and merge conflicts these are
based on Rafael's pm-wakeirq and Greg's tty-next branches.
