d9f998639f pinctrl: samsung: fix suspend/resume functionality
The GPIO states need to be restored after s2r and this is not currently
supported in the pinctrl driver. This patch saves the gpio states before
suspend and restores them after resume.

Saving and restoring is done very early using syscore_ops and must
happen before pins are released from their powerdown state.

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.

86c976e43d pinctrl: abx500: Rejiggle platform data and DT initialisation
Platform Data is invariably populated for this driver, even when
booting with Device Tree. Thus the Device Tree probing code encased
within the first check for Platform Data will never executed, causing
the driver to fail when DT is enabled.

This patch fixes the aforementioned regression by rejigging the
probe() semantics to attempt to extract a platform ID from Device Tree
if one can not be sourced from platform data.

A pointer to GPIO platform data is always passed to the driver now, so
there's little point in checking for 'pdata' and executing the DT case if
it's not there. The difference between booting with DT and !DT is when
booting with DT, plat_id is not populated. Thus, in the DT case we have
to use a DT match table in order to find out which platform we're
executing on. So, we're changing the semantics here to only use the
match table if no plat_id is supplied though platform data.

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.

 It would be good to get feedback on the location of the "mbus"
 driver. Since this is used on multiple platforms may potentially
 get shared with other architectures (powerpc and arm64), it
 was moved to drivers/bus/. We expect other similar drivers to
 get moved to the same place in order to avoid creating more
 top-level directories under drivers/ or cluttering up the
 messy drivers/misc/ even more.

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.

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.

 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required

dfab34aa61 ARM: arm-soc device-tree updates for 3.10, part 1
Device-tree updates for 3.10. The bulk of the churn in this branch is due
 to i.MX moving from C-defined pin control over to device tree, which is
 a one-time conversion that will allow greater flexibility down the road.
 
 Besides that, there's PCI-e bindings for Marvell mvebu platforms and a
 handful of cleanups to tegra due to the new include file functionality
 of the device tree compiler.

42fed7ba44 pinctrl: move subsystem mutex to pinctrl_dev struct
This mutex avoids deadlock in case of use of multiple pin
controllers. Before this modification, by using a global
mutex, deadlock appeared when, for example, a call to
pinctrl_pins_show() locked the pinctrl_mutex, called the
ops->pin_dbg_show of a particular pin controller. If this
pin controller needs I2C access to retrieve configuration
information and I2C driver is using pinctrl to drive its
pins, a call to pinctrl_select_state() try to lock again
pinctrl_mutex which leads to a deadlock.

Notice that the mutex grab from the two direction functions
was moved into pinctrl_gpio_direction().

For several cases, we can't replace pinctrl_mutex by
pctldev->mutex, because at this stage, pctldev is
not accessible :
	- pinctrl_get()/pinctrl_put()
	- pinctrl_register_maps()

So add respectively pinctrl_list_mutex and
pinctrl_maps_mutex in order to protect
pinctrl_list and pinctrl_maps list instead.

Reintroduce pinctrldev_list_mutex in
find_pinctrl_by_of_node(),
pinctrl_find_and_add_gpio_range()
pinctrl_request_gpio(), pinctrl_free_gpio(),
pinctrl_gpio_direction(), pinctrl_devices_show(),
pinctrl_register() and pinctrl_unregister() to
protect pinctrldev_list.

Changes v2->v3:
- Fix a missing EXPORT_SYMBOL_GPL() for pinctrl_select_state().

Changes v1->v2:
- pinctrl_select_state_locked() is removed, all lock mechanism
  is located inside pinctrl_select_state(). When parsing
  the state->setting list, take the per-pin-controller driver
  lock. (Patrice).
- Introduce pinctrldev_list_mutex to protect pinctrldev_list
  in all functions which parse or modify pictrldev_list.
  (Patrice).
- move find_pinctrl_by_of_node() from pinctrl/devicetree.c to
  pinctrl/core.c in order to protect pinctrldev_list.
  (Patrice).
- Sink mutex:es into some functions and remove some _locked
  variants down to where the lists are actually accessed to
  make things simpler. (Linus)
- Drop *all* mutexes completely from pinctrl_lookup_state()
  and pinctrl_select_state() - no relevant mutex was taken
  and it was unclear what this was protecting against. (Linus)

f07512e615 pinctrl/pinconfig: add debug interface
This update adds a debugfs interface to modify a pin configuration
for a given state in the pinctrl map. This allows to modify the
configuration for a non-active state, typically sleep state.
This configuration is not applied right away, but only when the state
will be entered.

This solution is mandated for us by HW validation: in order
to test and verify several pin configurations during sleep without
recompiling the software.

Change log in this patch set;
Take into account latest feedback from Stephen Warren:
- stale comments update
- improved code efficiency and readibility
- limit size of global variable pinconf_dbg_conf
- remove req_type as it can easily be added later when
add/delete requests support is implemented

e16415313c pinctrl: imx: move hard-coding data into device tree
Currently, all imx pinctrl drivers maintain a big array of struct
imx_pin_reg which hard-codes data like register offset and mux mode
setting for each pin function.  Every time a new imx SoC support is
added, we need to add such a big mount of data.  With moving to single
kernel build, it's only matter of time to be blamed on memory consuming.

With DTC pre-processor support in place, the patch moves all these data
into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and
changing the PIN_FUNC_ID parsing code a little bit.

The pin id gets re-numbered based on mux register offset, or config
register offset if the pin has no mux register, so that kernel can
identify the pin id from register offsets provided by device tree.

As a bonus point of the change, those arbitrary magic numbers standing
for particular PIN_FUNC_ID in device tree sources are now replaced by
macros to improve the readability of dts files.

The pin functions associated to the ethernet controller were introduced

dc2d3db813 Clean-up for omap2+ timers from Jon Hunter <jon-hunter@ti.com>:
This series consists mainly of clean-ups for clockevents and
 clocksource timers on OMAP2+ devices. The most significant change
 in functionality comes from the 5th patch which is changing the
 selection of the clocksource timer for OMAP3 and AM335x devices
 when gptimers are used for clocksource.
 
 Note that this series depends on 7185684 (ARM: OMAP: use
 consistent error checking) in RMK's tree and 960cba6 (ARM:
 OMAP5: timer: Update the clocksource name as per clock data)
 in omap-for-v3.10/fixes-non-critical. So this branch is based
 on a merge of 7185684 and omap-for-v3.10/fixes-non-critical
 to avoid non-trivial merge conflicts.

Each pin within the controller is capable of operating as a GPIO or as

In this error code, we want to call pinmux_disable_setting() where

And when pinconf_apply_setting() was called, we can't do much to undo
the pin muxing (the closest thing I can think about for "unmuxing" a pin

0b7d782022 ARM: shmobile: r8a7740: Migrate from INTC to GIC
With the added capabilty of the intc_irqpin driver to handle shared
external IRQs, all prerequisites are fulfilled and we are ready to
migrate completely to GIC. This includes the following steps:

- Kconfig:	select ARM_GIC and RENESAS_INTC_IRQPIN
- intc-r8a7740: Throw out all legacy INTC code and init the GIC. We need
  		to mask out all shared IRQs as it is needed by the
		shared intc_irqpin driver.
- setup-r8a7740: Add 4 irqpin devices to handle external IRQs and update
		all IRQ numbers to point to the GIC SPI.
- board-armadillo: Update all IRQ numbers to point to the GIC SPI.
- pfc-r8a7740:	Update all IRQ numbers of the GPIOs to point to the GIC
		SPI.

341eb5465f ARM: shmobile: INTC External IRQ pin driver on sh73a0
Adjust the sh73a0 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ31.

This removes quite a bit of special-case code
in intc-sh73a0.c but the number of lines get
replaced with platform device information in
setup-sh73a0.c. The PFC code is also adjusted
to make gpio_to_irq() return the correct
interrupt number.

At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.
