[PATCH v3 0/2] mfd: MAX8997: Support irq domain for Maxim MAX8997

Posted by Chanwoo Choi 
This patchset add support irq domain for Maxim MAX8997 interrupts.

The first patch is based on patch written by Thomas Abraham and fix
two bug which set max8997->irq_domain instead of NULL pointer and
correct wrong parameter by Chanwoo Choi.
- https://lkml.org/lkml/2012/4/18/145
The second patch use irq domain for MAX8997 muic interrupt instead
of irq_base in platform data of MAX8997 driver.

I do explain the history of this patchset. The below patch was written
by Thomas Abraham and it was applied on regulator.git repository.
- http://git.kernel.org/?p=linux/kernel/git/broonie/regulator.git;a=commit;h=98d8618af37728f6e18e84110ddb99987b47dd12
But, this patch had occurred build break, it was reported by Stephen
Rothwell when build max8997-muic driver(drivers/misc/max8997-muic.c) and
then this patch was reverted by Mark Brown. You can check reverted patch
on below patch.
- http://git.kernel.org/?p=linux/kernel/git/broonie/regulator.git;a=commit;h=82b719b11fd750188c125078ad6a6c0d23219dfb

Then, I post this patchset which is based on patch written by Thomas Abraham
to add support irq domain for Max MAX8997 interrupts with bug fix. Also, I had
to modify max8997-muic driver to avoid build break.

But,I posted following patchset related to extcon-max8997 driver. The below
patchset support Extcon framework in extcon-max8997 driver to control
external connector instead of max8997-muic driver. So, first patch add
MAX8997 extcon driver(drivers/extcon/extcon-max8997.c) and last patch remove
old MAX8997 muic driver(drivers/misc/max8997-muic.c).
- https://lkml.org/lkml/2012/5/8/98
The patchset which add extcon-max8997 driver was applied in below
git repository of Greg Kroah-Hartman.
- http://git.kernel.org/?p=linux/kernel/git/gregkh/driver-core.git;a=shortlog;h=refs/heads/driver-core-next

So, I think that this patchset should be applied on the git reposity
of Greg to remove possible conflict issue when merged because old max8997-muic
driver(drivers/misc/max8997-muic.c) is existed on regulator.git of Mark
Brown.

v2
- Fix typo when free_irq() in max8997_muic_probe()

v3
- Fix build break when extcon-max8997 is built as module
