Support for PCA9539 as a GPIO chip is separated into two patches:
0001 - gpiolib: basic support for 16-bit PCA9539 GPIO expander
0002 - gpiolib: add Generic IRQ support for 16-bit PCA9539 GPIO expander
the 2nd one uses workqueue for IRQ handling due to the interrupt mode
nature of the i2c-core, thus making it a separate patch.

Note that the situation could change according to the discussion in

I'm afraid to have to say this, but your message (with its broken CC
header) has caused several people to be unsubscribed from this mailing
list.
The reason seems to be that the list expander rejected your message,
which causes bounces to be sent back to mailman for a _ton_ of people.
Strangely enough, I run the exact same check ("headers_syntax") on all
messages the list server receives, and when I test it with your message,
it correctly rejects it. Yet somehow it didn't earlier. No idea.
In any case, EVERYONE, please drop the invalid "David," in the CC list.
Jean,
I'd like to postpone the corresponding change to the point that
polling i2c patch is merged.
