The SAMA5 and SAM9x5 series both have drive strength
options for the PIOs. This patch adds the ability to set
one of three hardware options for drive strengths of low,
medium or high for the each pin. The actual current output
of the chip based on the setting is defined in the datasheets
and varies per pins separate from banks and with supply
voltage.
This patch adds three new dt-bindings that allow setting the
strength when configuring pins. By default, no change will
be made to the drive strength of a pin from its reset value.
Due to the difference between the register addresses of the
SAMA5 and SAM9x5 series, a new sama5d3-pinctrl id was added.

The timer driver is using some global variables to define some variables it has
to use in most of its functions, like the base address.
Use some container_of calls to have a single dynamic (and local) variable to
hold this content.
The only exception is in the !DT case, where the call chain to
at91sam926x_ioremap_pit and then at91sam926x_pit_init as init_time makes it
hard for the moment to pass the physical address of the timer.

The PIT timer driver until now had a single probe function, disregarding wether
it was probed through DT or in the old-style way. This code later on was
calling some DT function to retrieve the proper values for its base address,
interrupts and clocks.
While this was working, it was preventing the usage of CLOCKSOURCE_OF_DECLARE,
and the two different probe path were not as clearly separated as they could
be.
Rework the probe path to take this into account, and switch to
CLOCKSOURCE_OF_DECLARE.

Until now, the machines, even when CONFIG_OF was enabled, were calling
at91sam926x_ioremap_pit to try to map the PIT address using the defined
physical address.
Obviously, with DT, it's not appropriate anymore, and some code was added to
the function to deal with this case.
Unfortunately, this code was conditionned on CONFIG_OF, which can be enabled,
even though no DT was actually used, which would result in such a case, to this
code being executed, without any reason.
Moreover, the logic that was here before to bail out of the function just check
in the DT to see if the PIT node is there, which is the case in all our DTSI.
All this can be made much more straightforward just by using
of_have_populated_dt to bail out.

- Start to kill off the return value from gpiochip_remove()

checks inside the drivers/gpio directory. The rationale
is: well what were we supposed to do if there is an error
code? Not much: print an error message. And gpiolib already

- Some cleanups of hairy gpiolib code, make some functions

they are not exported, remove gpiod_lock/unlock_as_irq()
as the existing function is for driver-internal use and

- Support the GPIOF_ACTIVE_LOW flag from gpio_request_one()

Merge tag 'drivers-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver changes from Olof Johansson:
"A handful of driver-related changes. We've had a bunch of them going
in through other branches as well, so it's only a part of what we
really have this release.
Larger pieces are:
- Removal of a now unused PWM driver for atmel
[ This includes AVR32 changes that have been appropriately acked ]
- Performance counter support for the arm CCN interconnect
- OMAP mailbox driver cleanups and consolidation
- PCI and SATA PHY drivers for SPEAr 13xx platforms
- Redefinition (with backwards compatibility!) of PCI DT bindings for
Tegra to better model regulators/power"
Note: this merge also fixes up the semantic conflict with the new
calling convention for devm_phy_create(), see commit f0ed817638 ("phy:
core: Let node ptr of PHY point to PHY and not of PHY provider") that
came in through Greg's USB tree.
Semantic merge patch by Stephen Rothwell <sfr@canb.auug.org.au> through
the next tree.

- Qualcomm APQ8064 and APQ8084 SoCs and eval boards
- Nvidia Jetson TK1 development board (Tegra T124-based)
Two new SoCs that didn't need enough new platform code to stand out
enough for me to notice when writing the SoC tag, but that adds new DT
contents are:
- TI DRA72

A quite large set of SoC updates this cycle. In no particular order:
- Multi-cluster power management for Samsung Exynos, adding support for
big.LITTLE CPU switching on EXYNOS5
- SMP support for Marvell Armada 375 and 38x
- SMP rework on Allwinner A31
- Xilinx Zynq support for SOC_BUS, big endian
- Marvell orion5x platform cleanup, modernizing the implementation and
moving to DT.
- _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
that their platform can be enabled in the same kernel binary as most
of the other v7 platforms in the tree. \o/ The work isn't quite complete,
there's some driver fixes still needed, but the basics now work.

On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.
Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.
This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

at91_adc now supports reading a touchscreen for ADCs without a TSMR register.
Enable touchscreen support through at91_adc. This allows to use both a
touchscreen and the remaining ADC channel at the same time.
Also, lower the clock for the ADC as it allows to have more stable reads and
this is the speed used by atmel_tsadcc.
It lowers the maximum throughput rate from 440000 samples per second to 12958
samples per second. It shouldn't be an issue as the CPU is not able to keep up
reading samples at that frequency.

* The Qualcomm MSM platform is split out into legacy mach-msm and

This patch prepare the transition to common clk for sam9 dt boards by
replacing the timer init callback.
Clocks registration cannot be done in early init callback (as formerly done
by the old clk implementation) because it requires dynamic allocation
which is not ready yet during early init.
In the other hand, at91 clocks must be registered before
at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver
request the master clk (mck).
A new function (at91sam9_dt_timer_init) is created to fullfil these needs.
This function registers all at91 clks using the dt definition before
calling the PIT init function.
The device tree clock registration is enabled only if common clk is
selected. Else the old clk registration is been done during
at91_dt_initialize call.

"New core SoC-specific changes.
New platforms:
* Introduction of a vendor, Hisilicon, and one of their SoCs with
some random numerical product name.
* Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m,
i.e. !MMU).
* Marvell Berlin series of SoCs, which include the one in Chromecast.

This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep it
strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared with Mike
Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.
* Removal of some header files on exynos to prepare for multiplatform

While <mach/timex.h> isn't used for multi-platform builds since long it
still is for "normal" builds. As the previous patches fix all sites to
not make use of this per-platform file, it can go now for good also for
platforms that are not (yet) converted to multi-platform.
While at it there are no users of CLOCK_TICK_RATE any more, so also drop
the dummy #define.

The platform specific <mach/timex.h> will be removed in a later patch.
So move its only still used symbol to a different header specific for
the only machine still using it. Also add a few explicit includes of

This passes the errata fix using a GPIO to control the RTS pin
on one of the AT91 chips to use gpiolib instead of the
AT91-specific interfaces. Also remove the reliance on
compile-time #defines and the cpu_* check and rely on the
platform passing down the proper GPIO pin through platform
data.
This is a prerequisite for getting rid of the local GPIO
implementation in the AT91 platform and move toward
multiplatform.
The patch also adds device tree support for getting the
RTS GPIO pin from the device tree on DT boot paths.

This AT91 specific Kconfig option removed the code that dealt with
programmable clocks. Each AT91 SoC embeds programmable clocks and
there is little gain to remove this code in case that such a clock
is not used.
If this option is not selected, it causes certain drivers to fail
to build. We simply remove this option instead of adding code just
to build a workaround.

Another batch of fixes for ARM SoCs for 3.13. The diffstat is large,
mostly because of:
- Another set of fixes to fix regressions caused by moving OMAP from board
files to DT. Tony thinks this was the last major set of fixes, with
maybe just a few small patches to follow.
- More fixes for Marvell platforms, most dealing with misdescribed PCIe
hardware, i.e. incorrect number of busses on some SoCs, etc. The line
delta adds up due to various ranges moving around when this is fixed.
But there's also:
- Some smaller tweaks to defconfigs to make more boards bootable in my
test setup for better coverage.
- There are also a few other smaller fixes, a short series for at91, a couple
of reverts for ux500, etc.

This patch prepare the transition to common clk for sama5 dt boards by
replacing the timer init callback.
Clocks registration cannot be done in early init callback (as formerly done
by the old clk implementation) because it requires dynamic allocation
which is not ready yet during early init.
In the other hand, at91 clocks must be registered before
at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver
request the master clk (mck).
A new function (at91sama5_dt_timer_init) is created to fullfil these needs.
This function registers all at91 clks using the dt definition before
calling the PIT init function.
The device tree clock registration is enabled only if common clk is
selected. Else the old clk registration is been done during
at91_dt_initialize call.

This patch adds the following Kconfig options to prepare the transition to
common clk framework:
- AT91_USE_OLD_CLK: this option is selected by every SoC which does not
support new at91 clks based on common clk framework (SoC which does not
define the clock tree in its device tree).
This options is also selected when the user choose non dt boards support
(new at91 clks can only be registered from a device tree definition).
- COMMON_CLK_AT91: this option cannot be selected directly. Instead it is
enabled if these 3 conditions are met:
* at least one of the selected SoCs have a PMC (Power Management
Controller) Unit
* device tree support is enabled
* the old at91 clk implementation is disabled (every selected SoC define
its clks in its device tree and non dt boards support is disabled)
- OLD_CLK_AT91: this option cannot be selected directly. Instead it is
enabled if these 2 conditions are met:
* at least one of the selected SoCs have a PMC (Power Management
Controller) Unit
* at least one of the selected SoCs does not define its clks in its
device tree or non dt-boards support is enabled
This patch selects AT91_USE_OLD_CLK in all currently supported SoCs. These
selects will be removed after clk definitions are properly added in each
soc's device tree.
It also selects AT91_USE_OLD_CLK in all non-dt boards support.
AT91_PMC_UNIT references are replaced by OLD_CLK_AT91, because PMC Unit is
enabled for both old and common clk implementations, and old clk
implementation should not be compiled if COMMON_CLK is enabled.
To avoid future link errors, a new stub is created for at91_dt_clock_init
function if OLD_CLK_AT91 is disabled.
A new check is added in dt init functions (setup.c) to prepare for SoCs
supporting new clk implementation. These SoCs won't setup the
register_clocks callback (clk registration is done using of_clk_init).

With some devices, transfer hangs during I2C frame transmission. This issue
disappears when reducing the internal frequency of the TWI IP. Even if it is
indicated that internal clock max frequency is 66MHz, it seems we have
oversampling on I2C signals making TWI believe that a transfer in progress
is done.
This fix has no impact on the I2C bus frequency.

The timer code for at91rm9200 was already converted some time ago by
Shawn Guo in commit 838a2ae (ARM: use clockevents_config_and_register()
where possible) but because of a rounding issue in the timer core this
resulted in an easily reproducible oops. So it was reverted (commit
b7a8ca5 (ARM: at91: rm9200 fix time support)) which stopped the oops
from happening because min_delta_ns is increased by one in arch code
which stopped from problem from happening.
Now that the timer core problem is fixed (commit a4578ea (clockevents:
Sanitize ticks to nsec conversion)), we can switch back to the
clockevents_config_and_register helper.

Merge tag 'at91-fixes-non-critical' of git://github.com/at91linux/linux-at91 into fixes
From Nicolas Ferre, fixes for early boot hangs on at91:
Fixes for RTT & RTC interrupts that can fire early during boot process
and kill the system.
* tag 'at91-fixes-non-critical' of git://github.com/at91linux/linux-at91:
ARM: at91: fix hanged boot due to early rtt-interrupt
ARM: at91: fix hanged boot due to early rtc-interrupt
Make sure the RTT-interrupts are masked at boot by adding a new helper
function to be used at SOC-init.
This fixes hanged boot on all AT91 SOCs with an RTT, for example, if an
RTT-alarm goes off after a non-clean shutdown (e.g. when using RTC
wakeup).
The RTC and RTT-peripherals are powered by backup power (VDDBU) (on all
AT91 SOCs but RM9200) and are not reset on wake-up, user, watchdog or
software reset. This means that their interrupts may be enabled during
early boot if, for example, they where not disabled during a previous
shutdown (e.g. due to a buggy driver or a non-clean shutdown such as a
user reset). Furthermore, an RTC or RTT-alarm may also be active.
The RTC and RTT-interrupts use the shared system-interrupt line, which
is also used by the PIT, and if an interrupt occurs before a handler
(e.g. RTC-driver) has been installed this leads to the system interrupt
being disabled and prevents the system from booting.
Note that when boot hangs due to an early RTC or RTT-interrupt, the only
way to get the system to start again is to remove the backup power (e.g.
battery) or to disable the interrupt manually from the bootloader. In
particular, a user reset is not sufficient.

This branch contains code cleanups, moves and removals for 3.13.
Qualcomm msm targets had a bunch of code removal for legacy non-DT
platforms. Nomadik saw more device tree conversions and cleanup of old
code. Tegra has some code refactoring, etc.
One longish patch series from Sebastian Hasselbarth changes the init_time
hooks and tries to use a generic implementation for most platforms,
since they were all doing more or less the same things.
Finally the "shark" platform is removed in this release. It's been
abandoned for a while and nobody seems to care enough to keep it
around. If someone comes along and wants to resurrect it, the removal
can easily be reverted and code brought back.
Beyond this, mostly a bunch of removals of stale content across the
board, etc.

AT91 ADC hardware integrate touch screen support. So this patch add touch
screen support for at91 adc iio driver.
To enable touch screen support in adc, you need to add the dt parameters:
1. which type of touch are used? (4 or 5 wires), sample period time.
2. correct pressure detect threshold value.
In the meantime, since touch screen will use a interal period trigger of adc,
so it is conflict to other hardware triggers. Driver will disable the hardware
trigger support if touch screen is enabled.
This driver has been tested in AT91SAM9X5-EK and SAMA5D3x-EK.

Conflicts:
drivers/cpuidle/Kconfig.arm
drivers/cpuidle/Makefile
Using the platform driver model is a good way to separate the cpuidle specific
code from the low level pm code. It allows to remove the dependency between
these two components.
The platform_device is located in the pm code and a 'set' function has been
added to set the standby function from the AT91_SOC_START initialization
function. Each SoC with a cpuidle driver will set the standby function in the
platform_data field at init time. Then pm code will register the cpuidle
platform device.
The cpuidle driver will register the platform_driver and use the device's
platform_data as a standby callback in the idle path.
The at91_pm_enter function contains a { if then else } based on cpu_is_xx
similar to what was in cpuidle. This is considered dangerous when adding a new
SoC. Like the cpuidle driver, a standby ops is defined and assigned when the
SoC init function specifies what is its standby function and reused in the
at91_pm_enter's 'case' block.

This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM platform
code for include changes so we took it through our tree.

These changes from 30 individual branches for the most part update device
tree files, but there are also a few source code changes that have crept
in this time, usually in order to atomically move over a driver from
using hardcoded data to DT probing.
A number of platforms change their DT files to use the C preprocessor,
which is causing a bit of churn, but that is hopefully only this once.
There are a few conflicts with the other branches unfortunately:
* in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
from multiple branches. Need to be careful to have the right
set of closing braces as git gets this one wrong.
* In kirkwood.dtsi, one 'ranges' line got split into two lines, while
another line got added. Order of the lines does not matter.
* in sama5d3.dtsi, some cleanup was merged the wrong way, causing
a bogus conflict. We want the 'dmas' and 'dma-names' properties
to get added here.
* Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
* Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

This contains cleanups as preparation for other branches adding new

Most notable here is the removal of support for ATAGS based OMAP4
systems. Since all OMAP4 machines are fully functional with DT based
booting in 3.10, we can remove a lot of code here.
Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,
which means we need no machine descriptors in a lot more cases and
can boot additional machines by just having the respective device
drivers enabled.

booting in 3.10, we can remove a lot of code here.
Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,
which means we need no machine descriptors in a lot more cases and can
boot additional machines by just having the respective device drivers
enabled."

ARM: at91: Consolidate time keeping and irq enable
Enable core cpuidle timekeeping and irq enabling and remove that

introduced an additional zero to the state1 (suspend) target residency.
With a periodic tick, the cpu never enters the state1 with both 10000 and
100000.
With a tickless system, it enters to state1 much more often with the
initial value, roughly x7 more.
Fix it by setting the value to 10ms again.

This patch makes it static and stores the non-dt extern irq in the soc

to get the value for outside of the irq driver. It is useful for passing
its value to at91_aic_init().

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.

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.
