Andy Shevchenko 786e07ecb5 gpio-langwell: use managed functions pcim_* and devm_*
This makes the error handling much more simpler than open-coding everything and
in addition makes the probe function smaller an tidier.

Maxime Ripard 90dae4ebf0 gpio: mxs: Use set and clear capabilities of the gpio controller
The current driver doesn't use the set and clear registers found on the
mxs gpio controller.

This leads the generic gpio controller to be using some internal value
to avoid looking up the value stored in the registers, making it behave
pretty much like a cache.

This raises some coherency problem when a gpio is not modified by the
gpio controller, while it can easily be fixed by using the set and clear
registers.

David Cohen 2519f9abce gpio-langwell: fix irq conflicts when DT is not used
When DT is not used IOAPIC does not register irq domain. As result
IOAPIC won't care about gpio-langwell's virq and may cause conflict if
an irq number is equal to gpio-langwell's virq mapped beforehand.

This patch tells gpio_langwell to not ignore irq_base if != 0 and
preferably use it to avoid the conflict.

If DT is used, irq_base can safely be 0.

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.

The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

Heiko Stuebner af99a75074 pinctrl: Add pinctrl-s3c24xx driver
The s3c24xx pins follow a similar pattern as the other Samsung SoCs and
can therefore reuse the already introduced infrastructure.

The s3c24xx SoCs have one design oddity in that the first 4 external
interrupts do not reside in the eint pending register but in the main
interrupt controller instead. We solve this by forwarding the external
interrupt from the main controller into the irq domain of the pin bank.
The masking/acking of these interrupts is handled in the same way.

Furthermore the S3C2412/2413 SoCs contain another oddity in that they
keep the same 4 eints in the main interrupt controller and eintpend
register and requiring ack operations to happen in both. This is solved
by using different compatible properties for the wakeup eint node which
set a property accordingly.

Jon Hunter 352a2d5bfc gpio/omap: ensure gpio context is initialised
Commit a2797be (gpio/omap: force restore if context loss is not
detectable) broke gpio support for OMAP when booting with device-tree
because a restore of the gpio context being performed without ever
initialising the gpio context. In other words, the context restored was
bad.

This problem could also occur in the non device-tree case, however, it
is much less likely because when booting without device-tree we can
detect context loss via a platform specific API and so context restore
is performed less often.

Nevertheless we should ensure that the gpio context is initialised
on the first pm-runtime resume for gpio banks that could lose their
state regardless of whether we are booting with device-tree or not.

The context loss count was being initialised on the first pm-runtime
suspend following a resume, by populating the get_count_loss_count()
function pointer after the first pm-runtime resume. To make the code
more readable and logical, initialise the context loss count on the
first pm-runtime resume if the context is not yet valid.

Linus Torvalds 5647ac0ad4 Removal of GENERIC_GPIO for v3.10
GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
 cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
 possible to do so which has been causing confusion and breakage. This
 branch does the work to completely eliminate GENERIC_GPIO.
 
 However, it is not trivial to just create a branch to remove it. Over
 the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
 added to linux-next that conflicts with this branch. The following must
 be done to resolve the conflicts when merging this branch into mainline:
 
 * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
   replaced with CONFIG_GPIOLIB
 * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
   documentation.
 * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
 * definitions of the option in architecture Kconfig code should be deleted.
 
 Stephen has 3 merge fixup patches[1] that do the above. They are currently
 applicable on mainline as of May 2nd.

Linus Torvalds a8c4b90e67 ARM: arm-soc platform updates for 3.10, part 2
These patches are all for Renesas shmobile, and depend on the earlier
 pinctrl updates. Remarkably, this adds support for three new SoCs:
 r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is
 for pinctrl (using the new subsystem) and for clocks (not yet using the
 common clock subsystem). The latter will have to get converted in one
 of the upcoming releases, but shmobile is not ready for that yet.
 
 The series also contains Renesas shmobile board changes, adding one
 board file for each of the three new SoCs.  These boards are using a
 mix of classic and device-tree based probing, as there is still a lot of
 infrastructure in shmobile that has not been converted to DT yet. Once
 those are resolved to the degree that no board specific setup code is
 needed, they can get folded into the respective SoC setup files.

Merge tag 'soc-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform updates (part 2) from Arnd Bergmann:
 "These patches are all for Renesas shmobile, and depend on the earlier
  pinctrl updates.  Remarkably, this adds support for three new SoCs:
  r8a73a4, r8a73a4 and r8a7778.  The bulk of the code added for these is
  for pinctrl (using the new subsystem) and for clocks (not yet using
  the common clock subsystem).  The latter will have to get converted in
  one of the upcoming releases, but shmobile is not ready for that yet.

  The series also contains Renesas shmobile board changes, adding one
  board file for each of the three new SoCs.  These boards are using a
  mix of classic and device-tree based probing, as there is still a lot
  of infrastructure in shmobile that has not been converted to DT yet.
  Once those are resolved to the degree that no board specific setup
  code is needed, they can get folded into the respective SoC setup files."

Linus Torvalds 150a8dcf10 ARM: arm-soc board specific changes for 3.10, part 1
These changes are all for board specific files. These used to make up a
 large portion of the ARM changes in the past, but as we are generalizing
 the support and moving to device tree probing, this has gotten
 significantly smaller. The only platform actually adding new code here
 at the moment is Renesas shmobile, as they are still busy converting
 their code to device tree and have not come far enough to not need it.

Linus Torvalds 6fa52ed33b ARM: arm-soc driver changes for 3.10
This is a rather large set of patches for device drivers that for one
 reason or another the subsystem maintainer preferred to get merged
 through the arm-soc tree. There are both new drivers as well as
 existing drivers that are getting converted from platform-specific
 code into standalone drivers using the appropriate subsystem
 specific interfaces.
 
 In particular, we can now have pinctrl, clk, clksource and irqchip
 drivers in one file per driver, without the need to call into
 platform specific interface, or to get called from platform specific
 code, as long as all information about the hardware is provided
 through a device tree.
 
 Most of the drivers we touch this time are for clocksource. Since
 now most of them are part of drivers/clocksource, I expect that we
 won't have to touch these again from arm-soc and can let the
 clocksource maintainers take care of these in the future.
 
 Another larger part of this series is specific to the exynos platform,
 which is seeing some significant effort in upstreaming and
 modernization of its device drivers this time around, which
 unfortunately is also the cause for the churn and a lot of the
 merge conflicts.
 
 There is one new subsystem that gets merged as part of this series:
 the reset controller interface, which is a very simple interface
 for taking devices on the SoC out of reset or back into reset.
 Patches to use this interface on i.MX follow later in this merge
 window, and we are going to have other platforms (at least tegra
 and sirf) get converted in 3.11. This will let us get rid of
 platform specific callbacks in a number of platform independent
 device drivers.

Linus Torvalds a7726350e0 ARM: arm-soc cleanup for 3.10
Here is a collection of cleanup patches. Among the pieces that stand out are:
 
 - The deletion of h720x platforms
 - Split of at91 non-dt platforms to their own Kconfig file to keep them separate
 - General cleanups and refactoring of i.MX and MXS platforms
 - Some restructuring of clock tables for OMAP
 - Convertion of PMC driver for Tegra to dt-only
 - Some renames of sunxi -> sun4i (Allwinner A10)
 - ... plus a bunch of other stuff that I haven't mentioned

Turns out that multiplatform breaks some uses cases, such as when you

will be disabled by default.

Arnd Bergmann bd51de53e1 ARM: exynos: enable multiplatform support
This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.

The multiplatform variant has a number of limitations at the moment:

* It only supports DT-enabled machines. This is not a problem in
  the long run, as non-DT machines for exynos are going away.
  The main problem here is that the gpio code and the exynos_eint
  irqchip are not multiplatform capable but still required for
  ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
  multiplatform.

The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.

Mika Westerberg 12028d2d21 gpiolib-acpi: introduce acpi_get_gpio_by_index() helper
Instead of open-coding ACPI GPIO resource lookup in each driver, we provide
a helper function analogous to Device Tree version that allows drivers to
specify which GPIO resource they are interested (using an index to the GPIO
resources). The function then finds out the correct resource, translates
the ACPI GPIO number to the corresponding Linux GPIO number and returns
that.

Rafael J. Wysocki 7fc7acb9a0 gpio / ACPI: Handle ACPI events in accordance with the spec
Commit 0d1c28a (gpiolib-acpi: Add ACPI5 event model support to gpio.)
that added support for ACPI events signalled through GPIO interrupts
covered only GPIO pins whose numbers are less than or equal to 255.
However, there may be GPIO pins with numbers greater than 255 and
the ACPI spec (ACPI 5.0, Section 5.6.5.1) requires the _EVT method
to be used for handling events corresponding to those pins.

Moreover, according to the spec, _EVT is the default mechanism
for handling all ACPI events signalled through GPIO interrupts,
so if the _Exx/_Lxx method is not present for the given pin,
_EVT should be used instead.  If present, though, _Exx/_Lxx take
precedence over _EVT which shouldn't be executed in that case
(ACPI 5.0, Section 5.6.5.3).

Modify acpi_gpiochip_request_interrupts() to follow the spec as
described above and add acpi_gpiochip_free_interrupts() needed
to free interrupts associated with _EVT.

v3:
- removed mcp,chips device tree property in favour of a
    mcp,spi-present-mask and a flag for the pullup of every gpio
- seperated the match table. Now there is one for i2c and one for spi
- do the of reading stuff on stack of the probe function - no devm
    any more

v2:
- squashed booth patches together
- fixed build warning, when CONFIG_OF is not defined
- use of_match_ptr macro for of_match_table

Jon Hunter a2797beadf gpio/omap: force restore if context loss is not detectable
When booting with device-tree the function pointer for detecting context
loss is not populated. Ideally, the pm_runtime framework should be
enhanced to allow a means for reporting context/state loss and we could
avoid populating such function pointers altogether. In the interim until
a generic non-device specific solution is in place, force a restore of
the gpio bank when enabling the gpio controller.

Adds a new device-tree property for the OMAP GPIO controller to indicate
if the GPIO controller is located in a power-domain that never loses
power and hence will always maintain its logic state.

Jon Hunter 3513cdeccc gpio/omap: optimise interrupt service routine
The OMAP GPIO interrupt service routine is checking each bit in the
GPIO interrupt status register to see which bits are set. It is not
efficient to check every bit especially if only a few bits are set.
Therefore, instead of checking every bit use the __ffs() function,
which returns the location of the first set bit, to find all the set
bits.

This optimisation was suggested-by and developed in collaboration
with Felipe Balbi.

Tarun Kanti DebBarma 60b18b9aa4 gpio/omap: remove extra context restores in *_runtime_resume()
68942edb09 (gpio/omap: fix wakeups
on level-triggered GPIOs) already restores the fallingdetect and
risingdetect contexts in *_runtime_resume(). These registers were
modified in *_runtime_suspend() to include even those configured
as level-triggered since only edge-triggered gpios can generate
wakeup events. Therefore, the old context restores of the same
registers present later in the code is not needed any more.
Remove them.

Magnus Damm 119f5e448d gpio: Renesas R-Car GPIO driver V3
This patch is V3 of a GPIO driver for the R-Car series of
SoCs from Renesas. This driver is designed to be reusable
between multiple SoCs that share the same basic building block,
but so far it has only been used on R-Car H1 (r8a7779).

Each driver instance handles 32 GPIOs with individually
maskable IRQs. The driver operates on a single I/O memory
range and the 32 GPIOs are hooked up a single interrupt.

In the case of R-Car H1 either external IRQ pins or GPIOs
with interrupts can be used for on-board interupts. For
external IRQs 4 pins are supported, and in the case of GPIO
there are 202 GPIOS as 202 interrupts hooked up via 6 driver
instances and to the GIC and the Cortex-A9 Quad.

At this point this driver is interfacing as a regular
platform device driver. In the future DT support will be
submitted as an incremental feature patch.

For OMAP devices, if a gpio is being used as an interrupt source but has
not been requested by calling gpio_request(), a call to request_irq()
may cause the kernel hang because the gpio bank may be disabled and
hence the register access will fail. To prevent such hangs, test for

Jon Hunter ede4d7a5b9 gpio/omap: convert gpio irq domain to linear mapping
Currently the OMAP GPIO driver uses a legacy mapping for the GPIO IRQ
domain. This is not necessary because we do not need to assign a
specific interrupt number to the GPIO IRQ domain. Therefore, convert
the OMAP GPIO driver to use a linear mapping instead.

Please note that this also allows to simplify the logic in the OMAP
gpio_irq_handler() routine, by using irq_find_mapping() to obtain the
virtual irq number from the GPIO bank and bank index.

Heiko Stuebner 1c8408e313 ARM: S3C24XX: handle s3c2412 eints using new infrastructure
The s3c2412 handles the eints 0 to 3 different than all the other SoCs
of the 24xx range. These eints must be acked and masked in the regular
bits as well as the bits 0 to 3 of the eint registers, which are unused
on the other SoCs.

This of course can be realized using the new infrastructure with the
eint bits in the main register being the parent interrupts of the
same bits in the eint register.

The s3c2412 therefore gets its own IRQ_EINT0 to 4 constants that
reside in the newly created gap before IRQ_EINT4. gpio-samsung, as the
only user of these is modified to return the correct values when
handling gpio_to_irq requests on s3c2412 based machines.

Due to lack of hardware this is compile tested only, but should
hopefully work as intended.

Linus Torvalds ab7826595e 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.

Linus Torvalds b274776c54 arm-soc: cleanups
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.

 - Selftest bugfixes and improvements
 - New function for counting phandles stanzas in a property
 - constify argument to of_node_full_name()

Magnus Damm c7886b1827 gpio: em: Use irq_domain_add_simple() to fix runtime error
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
selection of MFD_CORE.

Grant Likely e80beb27d2 gpio: Make of_count_named_gpios() use new of_count_phandle_with_args()
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.

Tony Prisk 9f01d30ee1 gpio/vt8500: memory cleanup missing
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.

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,

The new code should preserve the exact same GPIO number assignment
