Current status of interrupt handling capability of pca953x gpio driver.

Current status of interrupt handling capability of pca953x gpio driver.

[javier Martin]

Hi,
I saw a recent mail from Marc Zyngier on December about adding interrupt
handling capability to pca953x gpio driver. (
http://lists.infradead.org/pipermail/linux-arm-kernel/2009-December/006651.html
)
There has not been any activity since then (or at least I couldn't find
anything). What is the status regarding to mainline of these features?

Have changes proposed by Marc Zyngier accepted? If not, what points have to
be improved?

Thank you.

The patch is currently at it's 4th iteration (posted in February on LKML
http://lkml.org/lkml/2010/2/5/282) and sitting in Andrew Morton's mm tree.
It also has been successfully used on Blackfin boards.

When it comes to mainline merging, I really have no clue. The patch received very
little public comment (I only received a few private emails from people using it).

So if someone higher up in the food chain wants to carry that patch in his tree
and push it upstream, I can give it a respin.

I was planning on merging

gpio-pca953xc-add-interrupt-handling-capability.patch
gpio-pca953xc-add-interrupt-handling-capability-fix.patch
gpio-pca953xc-add-interrupt-handling-capability-v4.patch

into 2.6.34 unless someone stops me.

Looks great! Thanks a lot Andrew.

Now if I could have some comments on this [1] related patch?
It would make life a lot easier for driver developers.

Thanks,

        M.

Thank you for the information guys.

I will test that 4th iteration as soon as I get a prototype board with one
of these chips attached to it.

Greetings.
