Per Documentation/gpio.txt, gpio_request callbacks should return 0 on
success or a negative value on error. So it is not clear what was
meant by letting ichx_gpio_request return 1 in some cases, nor how a

ichx_gpio_check_available() returns either 0 or -ENXIO depending on whether
the given GPIO is available or not. However, callers of this function treat
the return value as boolean:

if (!ichx_gpio_check_available(gpio, nr))

which erroneusly fails when the GPIO is available and not vice versa.
Fix this by making the function return boolean as expected by the callers.

Merge tag 'mfd-3.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFS updates from Samuel Ortiz:
"This is the MFD pull request for the 3.9 merge window.
No new drivers this time, but a bunch of fairly big cleanups:
- Roger Quadros worked on a OMAP USBHS and TLL platform data
consolidation, OMAP5 support and clock management code cleanup.
- The first step of a major sync for the ab8500 driver from Lee
Jones. In particular, the debugfs and the sysct interfaces got
extended and improved.
- Peter Ujfalusi sent a nice patchset for cleaning and fixing the
twl-core driver, with a much needed module id lookup code
improvement.
- The regular wm5102 and arizona cleanups and fixes from Mark Brown.
- Laxman Dewangan extended the palmas APIs in order to implement the
palmas GPIO and rt drivers.
- Laxman also added DT support for the tps65090 driver.
- The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra
and Darren Hart.
- Linus Walleij patchset for the ab8500 driver allowed ab8500 and
ab9540 based devices to switch to the new abx500 pin-ctrl driver.
- The max8925 now has device tree and irqdomain support thanks to
Qing Xu.
- The recently added rtsx driver got a few cleanups and fixes for a
better card detection code path and now also supports the RTS5227
chipset, thanks to Wei Wang and Roger Tseng."

patch for s390. It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and
the page_test_and_clear_dirty primitive which makes the common memory

Heiko fixed most of the PCI related fallout, more often than not
missing GENERIC_HARDIRQS dependencies. Notable is one of the 3270

A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even specify
the driver they use, it can all get configured from the device tree
as we do for normal device drivers. The clocksource changes basically
touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose
their headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code.

Here is the big driver core merge for 3.9-rc1
There are two major series here, both of which touch lots of drivers all
over the kernel, and will cause you some merge conflicts:
- add a new function called devm_ioremap_resource() to properly be
able to check return values.
- remove CONFIG_EXPERIMENTAL
If you need me to provide a merged tree to handle these resolutions,
please let me know.
Other than those patches, there's not much here, some minor fixes and

Adjust the gpio-em.c driver to reconsider the pdata->irq_base
variable. Non-DT board code like for instance board-kzm9d.c
needs to operate of a static IRQ range for platform devices.
So this patch is updating the code to make use of the function
irq_domain_add_simple() instead of irq_domain_add_linear().
Fixes a EMEV2 / KZM9D runtime error caused by the following commit:
7385500 gpio/em: convert to linear IRQ domain

The VIA VX855/VX875 GPIO and RDC R-321x GPIO support drivers select
MFD_CORE which itself depends on GENERIC_HARDIRQ support.
So add this dependency to these two drivers as well to prevent

This patch replaces the horribly coded of_count_named_gpios() with a
call to of_count_phandle_with_args() which is far more efficient. This
also changes the return value of of_gpio_count() & of_gpio_named_count()
from 'unsigned int' to 'int' so that it can return an error code. All
the users of that function are fixed up to correctly handle a negative
return value.

This driver is missing a .remove callback, and the fail path on
probe is incomplete.
If an error occurs in vt8500_add_chips, gpio_base is not unmapped.
The driver is also ignoring the return value from this function so
if a chip fails to register it completes as successful.
Replaced pr_err with dev_err in vt8500_add_chips since the device is
available.
There is also no .remove callback defined so the function is added.

Add a pointer to the gpio_chip structure that references the array of
GPIO descriptors belonging to the chip, and update gpiolib code to use
this pointer instead of the global gpio_desc[] array. This is another
step towards the removal of the gpio_desc[] global array.

Make sure gpiolib works internally with descriptors and (chip, offset)
pairs instead of using the global integer namespace. This prepares the
ground for the removal of the global gpio_desc[] array and the

Re-implement gpiochip_find_base using the list of chips instead of the
global gpio_desc[] array. This makes it both simpler and more efficient,
and is needed to remove the global descriptors array.
The new code should preserve the exact same GPIO number assignment
policy as the code it is replacing. There shouldn't be any visible
change to the assigned GPIO numbers.

Add a list member to gpio_chip that allows all chips to be parsed
quickly. The current method requires parsing the entire GPIO integer
space, which is painfully slow. Using a list makes many chip operations
that involve lookup or parsing faster, and also simplifies the code. It
is also necessary to eventually get rid of the global gpio_desc[] array.
The list of gpio_chips is always ordered by base GPIO number to ensure
chips traversal is done in the right order.

All in-kernel users of class_find_device() don't really need mutable
data for match callback.
In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c)
this patch changes match callbacks to use const search data.
The const is propagated to rtc_class_open() and power_supply_get_by_name()
parameters.
Note that there's a dev reference leak in suspend_test.c that's not
touched in this patch.

Exporting gpios over sysfs GPIO interface throws genirq
error messages, i.e. on an mpc5121 based board exporting
GPIO 5 triggers it:
# echo 229 > /sys/class/gpio/export
genirq: Setting trigger mode 0 for irq 44 failed
(mpc512x_irq_set_type+0x0/0x18c)
Similar error messages appear in the kernel boot log since the
board specifies GPIOs for matrix keypad and also SD Card write
protect and card detect GPIOs in its device tree. For all these
GPIOs there is an error message in the log.
The issue is triggered by setting the irq type to IRQ_TYPE_NONE
in the driver's irq_domain map function mpc8xxx_gpio_irq_map().
...
mpc8xxx_gpio_irq_map
irq_set_irq_type
__irq_set_trigger
__irq_set_trigger() calls irq_set_type() callback of the mpc8xxx gpio
irq chip with the IRQ_TYPE_NONE in its 'flags' argument. This callback
is either mpc8xxx_irq_set_type() or mpc512x_irq_set_type(). Both these
functions return -EINVAL in the case if IRQ_TYPE_NONE is passed in the
flow_type argument. This return value triggers the observed error
message in __irq_set_trigger(). Modifying these callbacks to not
return an error in IRQ_TYPE_NONE case doesn't make any sense to me.
The line setting IRQ_TYPE_NONE type has been originally added by
commit 345e5c8a "powerpc: Add interrupt support to mpc8xxx_gpio".
At this time set_irq_type() checked its type argument and returned 0
if the type argument didn't specify any meaningful type in its type
sense bits (and thus was equal to IRQ_TYPE_NONE). Effectively this
line was a nop and I wonder what was the point of adding it.
Remove IRQ_TYPE_NONE setting in the irq_domain mapping function.
