Linus Torvalds 7307c00f33 arm-soc: late OMAP changes
This branch contains changes for OMAP that came in late during the release
 staging, close to when the merge window opened.
 
 It contains, among other things:
 
 - OMAP PM fixes and some patches for audio device integration
 - OMAP clock fixes related to common clock conversion
 - A set of patches cleaning up WFI entry and blocking.
 - A set of fixes and IP block support for PM on TI AM33xx SoCs (Beaglebone, etc)
 - A set of smaller fixes and cleanups around AM33xx restart and revision
   detection, as well as removal of some dead code (CONFIG_32K_TIMER_HZ)

Seung-Woo Kim 60460abffc ARM: dma-mapping: Add maximum alignment order for dma iommu buffers
Alignment order for a dma iommu buffer is set by buffer size. For
large buffer, it is a waste of iommu address space. So configurable
parameter to limit maximum alignment order can reduce the waste.

Pull signal handling cleanups from Al Viro:
 "This is the first pile; another one will come a bit later and will
  contain SYSCALL_DEFINE-related patches.

   - a bunch of signal-related syscalls (both native and compat)
     unified.

   - a bunch of compat syscalls switched to COMPAT_SYSCALL_DEFINE
     (fixing several potential problems with missing argument
     validation, while we are at it)

   - a lot of now-pointless wrappers killed

   - a couple of architectures (cris and hexagon) forgot to save
     altstack settings into sigframe, even though they used the
     (uninitialized) values in sigreturn; fixed.

   - microblaze fixes for delivery of multiple signals arriving at once

   - saner set of helpers for signal delivery introduced, several
     architectures switched to using those."

Linus Torvalds 8b5628ab83 arm-soc: virtualization changes
This contains parts of the ARM KVM support that have dependencies on
 other patches merged through the arm-soc tree. In combination with
 patches coming through Russell's tree, this will finally add full
 support for the kernel based virtual machine on ARM,  which has
 been awaited for some time now.
 
 Further, we now have a separate platform for virtual machines
 and qemu booting that is used by both Xen and KVM, separating
 these from the Versatile Express reference implementation.
 Obviously, this new platform is multiplatform capable so it
 can be combined with existing machines in the same kernel.

Linus Torvalds 3298a3511f arm-soc: multiplatform support
Converting more ARM platforms to multiplatform support. This time, OMAP
 gets converted, which is a major step since this is by far the largest
 platform in terms of code size. The same thing happens to the vt8500
 platform.
 
 Conflicts include:
 * Two mach/uncompress.h files are removed, the changes made to them
   elsewhere can be discarded now.
 * Moving the OMAP4 irq_match array has context clashes with turning
   omap4_sar_ram_init into an omap_early_initcall()

Linus Torvalds 7ae1c76ee5 arm-soc: pin muxing for sh-mobile
This is another cleanup series, containing the move of the Renesas
 SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
 generic pinctrl subsystem, changing it over to the common interfaces in
 the process.
 
 Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
 we're merging this large branch of pinctrl conversion through arm-soc,
 even though it contains the corresponding conversions for arch/sh. Main
 reason for this is tight dependencies (that will now mostly be broken)
 between the arch/sh and mach-shmobile implementations.
 
 There will be more of this in 3.10 to do device-tree bindings, but this
 is the initial conversion.

Linus Torvalds b274776c54 arm-soc: cleanups
A large number of cleanups, all over the platforms. This is dominated
 largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
 others moving code out of arch/arm into more appropriate subsystems.
 The clocksource and irqchip drivers are now abstracted to the point
 where platforms that are already cleaned up do not need to even specify
 the driver they use, it can all get configured from the device tree
 as we do for normal device drivers. The clocksource changes basically
 touch every single platform in the process.
 
 We further clean up the use of platform specific header files here,
 with the goal of turning more of the platforms over to being
 "multiplatform" enabled, which implies that they cannot expose
 their headers to architecture independent code any more.
 
 It is expected that no functional changes are part of the cleanup.
 The overall reduction in total code lines is mostly the result of
 removing broken and obsolete code.

Arnd Bergmann 1420b22b0b ARM: pick Versatile by default for !MMU
The introduction of ARCH_MULTIPLATFORM changed
the default for nommu kernels from Versatile to
Integrator, which is less common, and does not
currently build for allnoconfig because that does
not select any of the CPUs.

This also ensures that at least one of the three
board files in versatile are enabled, which lets
us successfully build an allnoconfig kernel.

Arnd Bergmann a5d533ee07 ARM: disable virt_to_bus/virt_to_bus almost everywhere
We are getting a number of warnings about the use of the deprecated
bus_to_virt function in drivers using the ARM ISA DMA API:

drivers/parport/parport_pc.c: In function 'parport_pc_fifo_write_block_dma':
drivers/parport/parport_pc.c:622:3: warning: 'bus_to_virt' is deprecated
(declared at arch/arm/include/asm/memory.h:253) [-Wdeprecated-declarations]

This is only because that function gets used by the inline
set_dma_addr() helper. We know that any driver for the ISA DMA API
is correctly using the DMA addresses, so we can change this
to use the __bus_to_virt() function instead, which does not warn.

After this, there are no remaining drivers that are used on
any defconfigs on ARM using virt_to_bus or bus_to_virt, with
the exception of the OSS sound driver. That driver is only used
on RiscPC, NetWinder and Shark, so we can set ARCH_NO_VIRT_TO_BUS
on all other platforms and hide the deprecated functions, which
is far more effective than marking them as deprecated, in order
to avoid any new users of that code.

prevent this problem for any future chips.

 1) The clock driver was located in arch/arm/mach-tegra/ rather than

 2) A single "Tegra clock" type was implemented, rather than separate

 3) Clock lookups by device drivers were still driven by device name
    and connection ID, rather than through device tree.
 
 This pull request solves all three issues. This required some DT changes
 to add clocks properties, and driver changes to request clocks more
 "correctly". Finally, this rework allows all AUXDATA to be removed from
 Tegra board files, and various duplicate clock lookup entries to be
 removed from the driver.

Santosh Shilimkar 8f0de0d62f ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZ
The timekeeping doesn't depend on HZ value in presence of fine grained
clocksource and hence there should not be any time drift because of HZ
value which was chosen to be divisor of 32768.

OMAP has been using HZ = 128 value to avoid any time drift issues
because of 32768 HZ clock. But with various measurements performed
with HZ = 100, no time drift is observed and it also proves the
point about HZ not having impact on time keeping on OMAP.

Mark Rutland 8a4da6e36c arm: arch_timer: move core to drivers/clocksource
The core functionality of the arch_timer driver is not directly tied to
anything under arch/arm, and can be split out.

This patch factors out the core of the arch_timer driver, so it can be
shared with other architectures. A couple of functions are added so
that architecture-specific code can interact with the driver without
needing to touch its internals.

The ARM_ARCH_TIMER config variable is moved out to
drivers/clocksource/Kconfig, existing uses in arch/arm are replaced with
HAVE_ARM_ARCH_TIMER, which selects it.

Merge tag 'bcm2835-for-3.9-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-rpi into next/cleanup

From Stephen Warren:
ARM: bcm2835: cleanup

This pull request simply converts the bcm2835 clocksource driver to use
the recently added CLKSRC_OF feature.

The branch is based on v3.8-rc3, followed by a merge of arm-soc's
timer/cleanup branch.

Olof Johansson af70fdc947 Merge branch 'marco-timer-cleanup-rebase' of git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel into next/soc
From Barry Song, this adds support for a new SoC from CSR; marco. It's
SMP, uses GIC instead of VIC and in general needs a bit of rework of
the platform code for setup, which this branch contains.

* 'marco-timer-cleanup-rebase' of git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel:
  ARM: PRIMA2: provide two DEBUG_LL ports for prima2 and marco
  ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructures
  ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for Marco
  ARM: PRIMA2: rtciobg: it is also compatible with marco
  ARM: PRIMA2: rstc: enable the support for Marco
  ARM: PRIMA2: mv timer to timer-prima2 as we will add timer-marco
  ARM: PRIMA2: initialize l2x0 according to mach from DT
  ARM: PRIMA2: enable AUTO_ZRELADDR for SIRF in Kconfig
  ARM: PRIMA2: add CSR SiRFmarco device tree .dts

Laurent Pinchart a47029c16a ARM: shmobile: Select PINCTRL
The pin control framework is required by mach-shmobile. Select it in
Kconfig.

This will be required when the sh-pfc driver will move to
drivers/pinctrl/.
