cd3fc1b9a3 ARM: SAMSUNG: pm: Adjust for pinctrl- and DT-enabled platforms
This patch makes legacy code on suspend/resume path being executed
conditionally, on non-DT platforms only, to fix suspend/resume of
DT-enabled systems, for which the code is inappropriate.

437d8ac510 ARM: EXYNOS: uncompress - print debug messages if DEBUG_LL is defined
Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.

Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.

With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.

Since commit 1977e6d8 (drm/exynos: change the method for getting the

named. This patch fixes probe failure in non-DT cases by adding
appropriate resource names to fimd0 platform device.

bb9055b274 ARM: late Exynos multiplatform changes
These continue the multiplatform support for exynos, adding support
 for building most of the essential drivers (clocksource, clk, irqchip)
 when combined with other platforms. As a result, it should become
 really easy to add full multiplatform exynos support in 3.11, although
 we don't yet enable it for 3.10.
 
 The changes were not included in the earlier multiplatform series
 in order to avoid clashes with the other Exynos updates.
 
 This also includes work from Tomasz Figa to fix the pwm clocksource
 code on Exynos, which is not strictly required for multiplatform,
 but related to the other patches in this set and needed as a bug
 fix for at least one board.

This series from Tomasz Figa restores support for the pwm clocksource
in Exynos, which was broken during the conversion of the platform
to the common clk framework. The clocksource is only used in one
board in the mainline kernel (universal_c210), and this makes it
work for DT based probing as well as restoring the non-DT based
case.

e3d98847de ARM: platform specific firmware interfaces for 3.10
Two platforms, bcm and exynos have their own firmware interfaces using
 the "secure monitor call", this adds support for those.
 
 We had originally planned to have a third set of patches in here, which
 would extend support for the existing generic "psci" call that is used
 on multiple platforms as well as Xen and KVM guests, but that ended up
 getting dropped because the patches were not ready in time.

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.

99bece775f Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c changes from Wolfram Sang:

 - an arbitration driver.  While the driver is quite simple, it caused
   discussion if we need additional arbitration on top of the one
   specified in the I2C standard.  Conclusion is that I accept a few
   generic mechanisms, but not very specific ones.

 - the core lost the detach_adapter() call.  It has no users anymore and
   was in the way for other cleanups.  attach_adapter() is sadly still
   there since there are users waiting to be converted.

 - the core gained a bus recovery infrastructure.  I2C defines a way to
   recover if the data line is stalled.  This mechanism is now in the
   core and drivers can now pass some data to make use of it.

 - bigger driver cleanups for designware, s3c2410

 - removing superfluous refcounting from drivers

 - removing Ben Dooks as second maintainer due to inactivity.  Thanks
   for all your work so far, Ben!

 - bugfixes, feature additions, devicetree fixups, simplifications...

99c6bcf46d ARM: arm-soc multiplatform updates for 3.10
More multiplatform enablement for ARM platforms. The ones converted in
 this branch are:
 - bcm2835
 - cns3xxx
 - sirf
 - nomadik
 - msx
 - spear
 - tegra
 - ux500
 
 We're getting close to having most of them converted!
 
 One of the larger platforms remaining is Samsung Exynos, and there are
 a bunch of supporting patches in this merge window for it. There was a
 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
 rebasing multiple dependent branches and they were stable by then.

4923ee444a Revert "ARM: exynos: enable multiplatform support"
This reverts commit bd51de53e1.

Turns out that multiplatform breaks some uses cases, such as when you
have an existing defconfig, since it adds the new EXYNOS_SINGLE config
option as a dependecy. As a result, nearly all exynos config options
will be disabled by default.

Reverting instead of rebasing since this branch is pulled in as a
dependency elsewhere.

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.

cc014f3e29 mmc: sdhci-s3c: remove platform dependencies
plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c
driver, so it can become a local file there and all other
inclusions removed.

plat/sdhci.h is used only to define the platform devices,
and with the exception of the platform_data structure not
needed by the driver, so we can split out the platform_data
definition instead and leave the rest to platform code.

788437273f spi: s3c64xx: move to generic dmaengine API
The spi-s3c64xx uses a Samsung proprietary interface for
talking to the DMA engine, which does not work with
multiplatform kernels.

This version of the patch leaves the old code in place,
behind an #ifdef. This can be removed in the future,
after the s3c64xx platform start supporting the regular
dmaengine interface. An earlier version of this patch was
tested successfully on exynos5250 by Padma Venkat.

The conversion was rather mechanical, since the samsung
interface is just a shallow wrapper around the dmaengine
interface.

9ee51f01ee tty: serial/samsung: make register definitions global
The registers for the Samsung S3C serial port are currently defined in
the platform specific arch/arm/plat-samsung/include/plat/regs-serial.h
file, which is not visible to multiplatform capable drivers.

Unfortunately, it is not possible to move the file into a more local
place as we should normally try to, because the same registers
may be used in one of four places:

* In the driver itself
* In platform-independent ARM code for early debug output
* In platform_data definitions
* In the Samsung platform power management code

I have also found no way to logically split out a platform_data
file, other than possibly move everything into
include/linux/platform_data, which also felt wrong. The only
part of this file that makes sense to keep specific to the s3c24xx
platform are the virtual and physical addresses defined here,
which are needed in no other location.

de88cbb7b2 arm: Move chained_irq_(enter|exit) to a generic file
These functions have been introduced by commit 10a8c383 (irq: introduce
entry and exit functions for chained handlers) in asm/mach/irq.h. This
patch moves them to linux/irqchip/chained_irq.h so that generic irqchip
drivers do not rely on architecture specific header files.

e636602ac2 i2c: s3c2410: move mach/regs-iic.h into i2c-s3c2410 device driver
The register definitions are only used in the driver itself.
This also removes the last dependency on plat/ includes from the
i2c driver.
