[PATCH V3 RESEND 0/4] mfd: tps65910: use regmap irq framework for interrupt

[Laxman Dewangan]

This patch series has following change:
- Use regmap irq framework for interrupt registration. Corrected the
  register bit definition for interrupts.
- Move the irq table to tps65910.c and get rid of tps65910-irq.c.
- Raarrange the init sequence of different sub moduled of tps65910 like
  irq, clock and then mfd devices.
- Export the irq domain handle from regmap to use in mfd driver.
- Pass the irq domain in mfd_add_devices to have proper interrupt mapping
  for sub devices like RTC.


Changes from V1: 
- rearrange patch on which older patch3 become the new patch 1.
- Add stub for new api in the regmap.
- Add empty line if paragraph change in description.

Changes from V2:
- Remove the older 4th patch where API for getting irq_domain was added
  in regmap. It is already taken care by Mark B.

  mfd: tps65910: move interrupt implementation code to mfd file
  mfd: tps65910: pass irq_domain when adding mfd sub devices

[PATCH V3 RESEND 1/4] mfd: tps65910: Initialize mfd devices after all initialization done

[Laxman Dewangan]

Add sub devices of tps65910 after all initialization like interrupt,
clock etc. is done. This will make sure that require data gets
initialized properly before sub devices probe's get called.

[PATCH RESEND V3 2/4] mfd: tps65910: use regmap irq framework for interrupt support

[Laxman Dewangan]

Implement irq support of tps65910 with regmap irq framework
in place of implementing locally.
This reduces the code size significantly and easy to maintain.

[PATCH V3 RESEND 3/4] mfd: tps65910: move interrupt implementation code to mfd file

[Laxman Dewangan]

In place of implementing the irq support in separate file,
moving implementation to main mfd file.
The irq files only contains the table and init steps only
and does not need extra file to have this only for this
purpose.

No change from V1, just rearrange this patch.
It was already reviwed by Mark and hence adding his reviewed by.

[PATCH V3 RESEND 4/4] mfd: tps65910: pass irq_domain when adding mfd sub devices

[Laxman Dewangan]

When adding the sub device "tps65910-rtc", is it passed the
IO resource IRQ for the interrupt number. This interrupt needs
to map in the device irq domain. Pass the irq domain of device
in mfd_add_devices() so that proper irq mapping can be done when
adding the sub device RTC.

Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com>
Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

- Remove older patch 4 and make this as 4th patch.
- Added reviwed by Mark as he already reviewed it.

The patchset looks fine, but it should either go through Mark's tree or I
should merge Mark's regmap_irq_get_domain patch to my for-next branch.
Mark, any preference ?

I don't mind that much, there's a tag in my regmap tree you can pull in
to integrate or I can apply things just as easily.

I merged your topic/domain branch into my for-next one and I applied Laxman
patches on top of it, thanks.

Thanks Samuel for taking care.
Just want to share info that other patch [PATCH V4 1/2] mfd: add TI 
TPS80031 mfd core driver also need ot go on same tree as this driver use 
the new api from regmap.

Thanks,
