[PATCH 00/12] mfd: twl: Fix for irqdomain/next + SPARSE_IRQ + MMC card detect

[Benoit Cousson]

Hi Samuel and Tony,

Here is a fix + cleanup + SPARSE_IRQ series for TWL4030 and TWL6030.

The first goal was to fix the current regression due to irqdomain
support inside twl-core for OMAP3 + twl4030.

The issue is that there is no quick and dirty fix for that, hence this
exhaustive series started by Felipe to add SPARSE_IRQ support for TWL
modules.

On top of that a bunch of code cleanup are done, and in order to make
the MMC card detect still operational, some fixes are needed in the
board file too.

Due to the modification in the SIH setup API, the twl4030-gpio driver
has to be updated as well.

It was then trivial to add some basic device tree support for the
twl4030-gpio driver.

Please note that this series does depend on the irqdomain/next series
from Grant.

These patches will be probably sent in separate pull request. The only
strong dependency is with the irqdomain series.

This series is available here for reference:
  git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git for_3.4/twl_irq_gpio_cleanup

This is not for pull-request, becasue it is based on irqdomain + OMAP
IRQ DT series + OMAP twl DT series yet to be pushed.

Regards,
Benoit
