[GIT PULL] omap generic wakeirq for v4.2 merge window

[GIT PULL] omap generic wakeirq for v4.2 merge window

[Tony Lindgren]

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.

Regards,

Tony

  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@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 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.

OK thanks -rc cycle should be doable too as these fix issues with
interrupt re-entrancy that's possible if the wakeirq and the
device IO interrupt ever fire at the same time. So far have not
seen that though.. But that's mostly luck.

Regrads,
