Ludovic Desroches c4b68520dc ARM: at91: add AIC5 support
The number of lines of AIC5 has increased from 32 to 128. Due to this
increase, a source select register has been introduced for the interrupt
line selection. Moreover, register mapping has been changed. For that reasons,
we need some dedicated callbacks for AIC5.
Power management is also concerned by these changes. On suspend, we can't get
the whole interrupt mask register as before, we have to read this register 128
times. To reduce this overhead, a snapshot of the whole IMR is maintained.

Ludovic Desroches 8fe82a5550 ARM: at91: sparse irq support
Enable sparse irq support for multisoc image. It involves to add the
NR_IRQS_LEGACY offset to static SoC irq number definitions since NR_IRQS_LEGACY
irq descs are allocated before AIC requests irq descs allocation.
Move NR_AIC_IRQS macro to a more appropiate place with the purpose to
remove mach/irqs.h later.

Paul Bolle 2d1c9ccd68 ARM: at91: remove two unused headers
Commit 82c583e3ae ("AT91RM9200 hardware
headers") introduced arch/arm/mach-at91/include/mach/at91_spi.h and
arch/arm/mach-at91/include/mach/at91_ssc.h. (These files were called
at91rm9200_spi.h and at91rm9200_ssc.h then.) That commit was added in
the v2.6.18 development cycle.

Nothing includes them now and nothing uses the named constants they
provide. (There's no way these named constants could be used unless
these files were included somehow.) It actually seems these two headers
have never been used since they were added to the tree. They can safely
be removed.

Linus Torvalds 9f639269ed arm-soc: support for new SoCs
Three new system-on-chip models are supported: the st-ericsson u9540
 in ux500, the sam9n12 in at91 and the emma ev2 in shmobile.
 
 Emma is a little bit special because it is completely unrelated to
 the classic shmobile models, but the new Renesas rmobile SoCs are a
 combination of things from both Emma and shmobile, so it was decided to
 have them all live in one directory.
 
 This also contains updates to existing shmobile soc code as well as some
 related board changes due to dependencies.

Linus Torvalds 9bc747bea5 arm-soc: First batch of cleanups
These cleanups are basically all over the place. The idea is to collect
 changes with minimal impact but large number of changes so we can avoid
 them from distracting in the diffstat in the other series.
 
 A significant number of lines get removed here, in particular because
 the ixp2000 and ixp23xx platforms get removed. These have never been
 extremely popular and have fallen into disuse over time with no active
 maintainer taking care of them. The u5500 soc never made it into a
 product, so we are removing it from the ux500 platform.
 
 Many good cleanups also went into the at91 and omap platforms, as has
 been the case for a number of releases.

Rob Herring 1ac02d7958 ARM: fix __io macro for PCMCIA
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.

This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

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..

Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: SoC specific updates" from Arnd Bergmann:
 "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.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"

Fix up some trivial conflicts, including the mentioned Tegra Makefile.

Nicolas Ferre beeaa103ee dmaengine: at_hdmac: add slave config operation
This patch introduces DMA_SLAVE_CONFIG to at_hdmac Atmel DMA driver.

It is needed to fix a regression in the use of atmel-mci.c driver on Atmel
AT91 platforms brouth by e2b35f3:
"dmaengine/dw_dmac: Fix dw_dmac user drivers to adapt to slave_config changes"

We remove some parts of the private structure "at_dma_slave" and use the
information provided by "struct dma_slave_config": source/destination
peripheral registers and access width.

AT_DMA_SLAVE_WIDTH_* values used previously are not needed anymore as we
now use the standard ones. Although some conversion functions are needed to
match register expected values.

Some AT91 sub-architecture specific files are slightly touched by this patch
but it cannot be split because it can break compilation.
