ce53044c68 arm-soc: driver specific updates
These changes are specific to some driver that may be used by multiple
 boards or socs. The most significant change in here is the move of the
 samsung iommu code from a platform specific in-kernel interface to the
 generic iommu subsystem.

bcd59b0f0c ARM: davinci: optimize the DMA ISR
The ISR does quiete a lot of hw access which could be avoided. First it
checks for a pending interrupt by reading alteast one register. Then it
checks for the "activated" slots by reading another register. This is
more or a less a must.
Now, once it found an active slot it does the same two reads again.
After that it "knows" that there must be a pending transfer however it
cross checks with the other register. There are 32 bit in an interger
which are polled instead of considering only the set bits and ignoring
those which are zero. This performs atleast 32 reads which could be
avoided. In case of a first match it does another read.
This patch reorganizes the access by re-using the register which have
been read and then uses ffs() to find the matching slot instead looping
over it. By doing this we get rid of the last (32 + 2 + hits) reads.

It is possible however that by really busy bank0 we never get to handle
bank1. If this is a problem, we could try to handle bank1 after we are
done with bank0 to check if there are any outstanding transfers.

To put some numbers on this, this is from spi transfer via spidev. The
first column is the number of total transfers, the time stamp is taken
before and after the ioctl():

|10000, min: 542us      avg: 591us
|20000, min: 542us      avg: 592us
|30000, min: 542us      avg: 592us
|40000, min: 542us      avg: 585us
|50000, min: 542us      avg: 593us

The same test case with the patch applied
|10000, min: 444us      avg: 493us
|20000, min: 444us      avg: 491us
|30000, min: 444us      avg: 489us
|40000, min: 444us      avg: 491us
|50000, min: 444us      avg: 492us

that is almost 100us that just went away.

477099f189 ARM: davinci: implement DEBUG_LL port choice
Apart from the necessity to do this change for multi-platform kernels
the previous logic depended on the zImage decompressor to write the
physical and virtual address to a magic memory location.
If the decompressor is unused or not correctly configured for the
current machid, the addruart macro was an infinite loop. Moreover
debugging the early zImage code was not possible either.

This fixes:
	WARNING: arch/arm/mach-davinci/built-in.o(.text+0x2d84): Section mismatch in reference from the function da850_evm_ui_expander_setup() to the (unknown reference) .init.data:(unknown)
	The function da850_evm_ui_expander_setup() references
	the (unknown reference) __initdata (unknown).
	This is often because da850_evm_ui_expander_setup lacks a __initdata
	annotation or the annotation of (unknown) is wrong.

Note this is a real issue because if the tca6416 driver only binds when
the init sections are already discarded da850_evm_ui_expander_setup is
called when da850_evm_devices might already be overwritten.

820d41cf0c ARM: cleanups of io includes
Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes,
 moving some of the oft-repeated macros to a common location and removing a bunch of
 boiler plate. This is another step closer to a common zImage for multiple platforms.

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..

 into 3.3. One bug fix was originally intended for 3.3 but accidentally

Merge branch 'fixes-non-critical' into next/drivers2

fixes-non-critical has already been merged upstream, and there are a
handful of annoying context conflicts that it makes sense to resolve
before sending up. Part of this is because there was parallel development
going on between more urgent fixes and general driver fixups, it should
settle down once the lpc32xx platform reaches a more steady state.

Conflicts:
	arch/arm/mach-lpc32xx/clock.c

6f6f6a7029 ARM: create a common IOMEM definition
Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

This fixes:

	WARNING: vmlinux.o(.text+0xd664): Section mismatch in reference from the function da850_register_pm() to the function .init.text:da8xx_get_mem_ctlr()
	The function da850_register_pm() references

	This is often because da850_register_pm lacks a __init

39c6d2d1d7 ARM: davinci: create new common platform header for davinci
Remove individual platform header files for dm365, dm355, dm644x
and dm646x and consolidate it into a single and common
header file davinci.h placed in arch/arm/mach-davinci.

This reduces the pollution in the include/mach and is consistent
with Russell's suggestions as part of his "pet peaves" mail.
(See #4 in: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/071516.html)

While at it, fix the forward declaration of spi_board_info,
and include the right header file instead.

The further patches in the series take  advantage of this consolidation
for easy implementation of IO_ADDRESS elimination.

30c9c5b157 ARM: davinci: convert to common sched_clock() implementation
Davinci has its own sched_clock() implementation, which gets in the
way of a single zImage. Moving to the common sched_clock framework
makes the code slightly cleaner.

f6f97588a4 ARM: davinci: update mdio bus name
Commit 5a05a8200a ("davinci_emac:
use an unique MDIO bus name") introduced during the v3.3 merge
window updated the davinci mdio bus name to make it unique.

Update the bus name in board files which use DaVinci MDIO bus
to match the new name. Without this PHY is not detected with
error like:

PHY 0:01 not found
net eth0: could not connect to phy 0:01

Tested on DM365 and DA850 EVMs.
