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.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next
Pull ARM SoC driver changes from Olof Johansson:
"SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.
This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.
The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.
After discussion at last year's KS (and some more on the mailing
lists), we are here adding a drivers/soc directory. The purpose of
this is to keep per-vendor shared code that's needed by different
drivers but that doesn't fit into the MFD (nor drivers/platform)
model. We expect to keep merging contents for this hierarchy through
arm-soc so we can keep an eye on what the vendors keep adding here and
not making it a free-for-all to shove in crazy stuff"

The following parameters are no longer needed by the edma driver since the
information can be obtained from the IP's CCCFG register:
n_channel, n_region, n_slot and n_tc.
Remove the n_cc as well since in this context it has no meaning. We have
separate edma_soc_info struct/eDMA3_CC instance so this member does not
make any sense (and the driver no longer uses it).

As Joel pointed out, edma_read_position() uses memcpy_fromio() to read
the parameter ram. That's not synchronized with the internal update as
it does a byte by byte copy. We need to do a 32bit read to get a
consistent value.
Further reading destination and source is pointless. In DEV_TO_MEM
transfers we are only interested in the destination, in MEM_TO_DEV we
care about the source. In MEM_TO_MEM it really does not matter which
one you read.
Simple solution: Remove the pointers, select dest/source via a bool
and return the read value.
Remove the export of this function while at it. The only potential
user is the dmaengine and that's always builtin.

The edmacc_param struct should follow the layout of the paRAM area in the
HW. Be explicit on the size of the fields (u32) and also mark the struct
as packed to avoid any padding on non 32bit architectures.

Pull part one of ARM SoC updates from Olof Johansson:
"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.
New SoC support added:
- Freescale i.MX6SX
- LSI Axxia AXM55xx SoCs
- Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
- STi STIH407
plus a large set of various smaller updates for different platforms.
I'm probably missing some important one here"

Pull i2c updates from Wolfram Sang:
"Here is the pull request from the i2c subsystem. It got a little
delayed because I needed to wait for a dependency to be included
(commit b424080a9e08: "reset: Add optional resets and stubs"). Plus,
I had some email problems. All done now, the highlights are:
- drivers can now deprecate their use of i2c classes. That shouldn't
be used on embedded platforms anyhow and was often blindly
copy&pasted. This mechanism gives users time to switch away and
ultimately boot faster once the use of classes for those drivers is
gone for good.
- new drivers for QUP, Cadence, efm32
- tracepoint support for I2C and SMBus
- bigger cleanups for the mv64xxx, nomadik, and designware drivers
And the usual bugfixes, cleanups, feature additions. Most stuff has
been in linux-next for a while. Just some hot fixes and new drivers
were added a bit more recently."

This patch refactors elm_load_syndrome() to make it scalable for newer
ECC schemes by removing scheme specific macros (like ECC_BYTES*xx),
and instead using ECC control information passed during elm_config.

ELM hardware engine is used by BCH ecc-schemes for detecting and locating ECC
errors. This patch adds the following checks for ELM hardware engine:
- ELM internal buffers are of 1K,
so it cannot process data with ecc-step-size > 1K.
- ELM engine can execute upto maximum of 8 threads in parallel,
so in *page-mode* (when complete page is processed in single iteration),
ELM cannot support ecc-steps > 8.

The problem that the set timings code contains the call of Davinci
platform function davinci_aemif_setup_timing() which is not
accessible if kernel is built for another platform like Keystone.
The Keysone platform is going to use TI AEMIF driver.
If TI AEMIF is used we don't need to set timings and bus width.
It is done by AEMIF driver.
To get rid of davinci-nand driver dependency on aemif platform code
we moved aemif code to davinci platform.
The platform AEMIF code (aemif.c) has to be removed once Davinci
will be converted to DT and use ti-aemif.c driver.

This atomic commit changes the Integrator clock implementation
and the machines to register clocks from the device tree and
use these instead of the previous hard-coded clocks.
In the clock implementation all hard-coded clocks and the
special initialization function call goes away, and is
replaced by two compatible strings for the two clocks
available on the core module.

next/cleanup
This cleanup series gets rid of <mach/timex.h> for platforms not using
ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
387798b (ARM: initial multiplatform support).)
To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc
(with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
Compared to the previous pull request there was another patch added that
fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
squash this fix into the original commit to save him from the need to
reverify the series.

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.

Some fields in platform data structure is never used by boards.
This patch removes these fields and as a result optimizes private
driver structure a bit. Additionally patch removes backligh_power()
callback, so if it will be needed in the future, this feature should
be added as pwm{gpio,etc.}-regulator to the board code or in the DTS.

Pull bulk of gpio updates from Linus Walleij:
"A pretty big chunk of changes this time, but it has all been on
rotation in linux-next and had some testing. Of course there will be
some amount of fixes on top...
- Merged in a branch of irqchip changes from Thomas Gleixner: we need
to have new callbacks from the irqchip to determine if the GPIO
line will be eligible for IRQs, and this callback must be able to
say "no". After some thinking I got the branch from tglx and have
switched all current users over to use this.
- Based on tglx patches, we have added some generic irqchip helpers
in the gpiolib core. These will help centralize code when GPIO
drivers have simple chained/cascaded IRQs. Drivers will still
define their irqchip vtables, but the gpiolib core will take care
of irqdomain set-up, mapping from local offsets to Linux irqs, and
reserve resources by marking the GPIO lines for IRQs.
- Initially the PL061 and Nomadik GPIO/pin control drivers have been
switched over to use the new gpiochip-to-irqchip infrastructure
with more drivers expected for the next kernel cycle. The
factoring of just two drivers still makes it worth it so it is
already a win.
- A new driver for the Synopsys DesignWare APB GPIO block.
- Modify the DaVinci GPIO driver to be reusable also for the new TI
Keystone architecture.
- A new driver for the LSI ZEVIO SoCs.
- Delete the obsolte tnetv107x driver.
- Some incremental work on GPIO descriptors: have
gpiod_direction_output() use a logical level, respecting assertion
polarity through ACTIVE_LOW flags, adding gpiod_direction_output_raw()
for the case where you want to set that very value. Add
gpiochip_get_desc() to fetch a GPIO descriptor from a specific
offset on a certain chip inside driver code.
- Switch ACPI GPIO code over to using gpiochip_get_desc() and get rid
of gpio_to_desc().
- The ACPI GPIO event handling code has been reworked after
encountering an actual real life implementation.
- Support for ACPI GPIO operation regions.
- Generic GPIO chips can now be assigned labels/names from platform
data.
- We now clamp values returned from GPIO drivers to the boolean [0,1]
range.
- Some improved documentation on how to use the polarity flag was
added.

The tnetv107x platform is getting removed, so this driver won't
be needed any more.

Commit 436d42c61c3e ("ARM: samsung: move platform_data definitions")
moved the files to the current location but forgot to remove the pointer
to its previous location. Clean it up. While at it also change the header
file protection macros appropriately.

This patch adds support for RS-485 (TIOCSRS485/TIOCGRS485) IOCTLs.
As a result this patch eliminate private driver header.

Always register GPIOs and use dynamic GPIO ID assignment.
This is no much worth if GPIOs is not used, but helps remove
private driver header and add DT support in the future.
Additionally, patch adds missing uart_unregister_driver()
call if probe() fails.
