omap generic wakeirq for v4.2 merge window

Hi,

Here's a late pull request that would be good to get into v4.2. This series mostly just drops code that's now unnecessary, and also fixes potential interrupt re-entrancy issues that the old handling has.

The series changes omap hsmmc, 8250_omap and omap-serial to use the Linux generic wakeirq. I had to redo the branch last week on recent tty-next branch because of a merge conflict. Other than that, these patches were already in Linux next earlier.

The pull request below also shows the related patches in Rafael's pm-wakeirq branch as I did not create a separate merge commit to base patches on.

This branch depends on both Rafael's pm-wakeirq and Greg's tty-next, so it should be sent separately towards the end of the merge window.

Merge branch 'wakeirq-8250' into omap-for-v4.2/wakeirq-v2 (2015-06-09 23:37:31 -0700)

----------------------------------------------------------------
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.

This branch depends on both Rafael's pm-wakeirq and Greg's tty-next, so it should be sent separately towards the end of the merge window.

This one is OK to merge now, both pm-wakeirq and tty-next dependencies have been merged. This leaves the following diffstat for thees changes:

OK, thanks. I'm collecting a few remaining things for a "late" branch, but if I miss the merge window, I'll queue it up for -rc2.
