705c75e3a1 ARM: S3C24XX: Correct CAMIF interrupt definitions
Properly define the CAMIF interrupt resources. This device have two
interrupts - corresponding to the "codec" and "preview" data paths.
IRQ_CAM is handled internally by the architecture and demultiplexed
to IRQ_S3C2440_CAM_C and IRQ_S3C2440_CAM_P - these interrupts only
should be handled in the driver.

bdd3cc26ba ARM: SAMSUNG: Update default rate for xusbxti clock
The rate of xusbxti clock is set in individual machine files.
The default value should be defined at the clock definition
and individual machine files should modify it if required.

3dca938656 ARM: SAMSUNG: Fix for S3C2412 EBI memory mapping
While upgrading the kernel on a S3C2412 based board I've noted
that it was impossible to boot the board with a 2.6.32 or upper
kernel. I've tracked down the problem to the EBI virtual memory
mapping that is in conflict with the IO mapping definition in
arch/arm/mach-s3c24xx/s3c2412.c.

d85d135d8b Omapdss driver changes for 3.5 merge window.
Lots of normal development commits, but perhaps most notable changes are:
 
 * HDMI rework to properly decouple the HDMI audio part from the HDMI video part.
 * Restructure omapdss core driver so that it's possible to implement device
   tree support. This included changing how platform data is passed to the
   drivers, changing display device registration and improving the panel driver's
   ability to configure the underlying video output interface.
 * Basic support for DSI packet interleaving

Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much
worse than they are: the exonys5 init code was refactored in commit
fd454997d6 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and
then commit f10590c983 ("ARM: EXYNOS: add GPC4 bank instance") added a
new gpio chip define and did tiny updates to the init code.

So the conflict diff looks like hell, but it's actually a fairly simple
change.

 It's touches a lot of different parts of the kernel, all USB drivers,
 due to some API cleanups (getting rid of the ancient err() macro) and
 some changes that are needed for USB 3.0 power management updates.
 
 There are also lots of new drivers, pimarily gadget, but others as well.
 We deleted a staging driver, which was nice, and finally dropped the
 obsolete usbfs code, which will make Al happy to never have to touch
 that again.
 
 There were some build errors in the tree that linux-next found a few
 days ago, but those were fixed by the most recent changes (all were due
 to us not building with CONFIG_PM disabled.)

A seperate bus_type instance is not required for EXYNOS5. The
existing bus_type instance used with EXYNOS4 is sufficient for
both EXYNOS4 and EXYNOS5. This also solves issue of uninitialized
usage of exynos4_subsys in EXYNOS4 power management code that is
reused for EXYNOS5 also. In addition to that, the existing
exynos4_subsys bus_type is renamed to exynos_subsys to indicate
that it is reused on both EXYNOS4 and EXYNOS5 platforms.

6a1e1d71d0 usb: gadget: patches for v3.5
This pull request is quite big, but mainly because there's a
 giant rework of the s3c_hsotg.c driver to make it friendlier
 for other users. Samsung Exynos platforms use the DesignWare
 Core USB2 IP from Synopsys so it's a bit unfair to have the
 driver work for Samsung platforms only. In short, the big
 rework is in preparation to make the driver more reusable.
 
 Another big rework in this pull request came from Ido, where
 he's removing the redundant pointer for the endpoint descriptor
 from the controller driver's own endpoint representation. The
 same pointer is available through the generic struct usb_ep
 structure.
 
 Also on this pull request is the conversion of a few extra
 controller drivers to the new style registration, which allows
 multiple controllers to be available on the same platform and
 helps remove global pointers from those drivers.
 
 Together with those big changes, there's the usual fixes and cleanups
 to gadget drivers. Nothing major.

a4196febbe video: s3c-fb: move video interface timing out of window setup data
The video interface timing is independent of the window setup data.
The resolution of the window can be smaller than that of the lcd
panel to which the video data is output.

So move the video timing data from the per-window setup data to the
platform specific section in the platform data. This also removes
the restriction that atleast one window should have the same
resolution as that of the panel attached.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

Pull "ARM: More SoC support updates" from Olof Johansson:
 "This branch contains a handful of updates of SoC base code that had
  dependencies on other external trees that have now been merged:

   * Support for the new EXYNOS5250 SoC from Samsung
   * SMP and power domain support for Tegra3 from NVIDIA
   * ux500 updates for exporting SoC information through sysfs"

Fix up trivial merge conflicts as per Olof.

34800598b2 ARM: driver specific updates
These are all specific to some driver. They are typically the platform
 side of a change in the drivers directory, such as adding a new driver
 or extending the interface to the platform. In cases where there is no
 maintainer for the driver, or the maintainer prefers to have the
 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.
 
 A much smaller set of driver updates that depend on other branches
 getting merged first will be sent later.
 
 The new export of tegra_chip_uid conflicts with other changes in fuse.c.
 In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
 the cleanup of the interrupt handling of that driver.

281b05392f ARM: SoC specific updates
These changes are all specific to an soc family or the code for
 one soc. Lots of work for Tegra3 this time, but also a lot of other
 platforms. There will be another (smaller) set of soc patches later in
 the merge window for stuff that has dependencies on external trees or
 that was sent just before the merge window opened.
 
 The asoc tree added a few devices to the i.mx platform, which conflict
 with other devices added in the same place here.
 
 The tegra Makefile conflicts between a number of branches, mostly because
 of changes regarding localtimer.c, which was removed in the end.
