Linus Torvalds c39e8ede28 ARM: A few more platform fixes for include file fallout
Two patches, one dealing with the system.h fallout, the other is a missing
 linux/bug.h in a place where ARRAY_SIZE() is used.

Pull a few more ARM platform fixes from Olof Johansson:
 "Apologies for back-to-back fixes pull requests, but one of the patches
  below are the kind we'll see posted over and over if we don't send it
  in.  I hadn't done the full sanity-check of defconfig builds by the
  time I sent up the other fixes yesterday or I would have included it
  then.

  Two patches, one dealing with the system.h fallout, the other is a
  missing linux/bug.h in a place where ARRAY_SIZE() is used."

Olof Johansson 86dfe446c2 ARM: fix builds due to missing <asm/system_misc.h> includes
This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.

I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

Linus Torvalds 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.

Linus Torvalds 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.

Fabio Estevam bb07d7511e ARM: mx3: Setup AIPS registers
It was observed on a mx31pdk board that audio playback only worked when the bootloader was Redboot, and
did not work when U-boot was used.

Comparing the sources of these bootloaders showed that the AIPS registers were not setup in U-boot.

Instead of relying on the bootloader to setup the AIPS registers, do it in the kernel so that audio
playback can work independantly of the bootloader being used.

Copied the AIPS settings from Redboot to the kernel.

Fabio Estevam 3ac804e311 ARM: mx3: Let mx31 and mx35 enter in LPM mode in WFI
The LPM field of register CCMR is used to select the mode that the processor will run
when it goes to WFI.

When mx31 enters in WFI mode the LPM field is at its reset value of 0,
which configures the mx31 to enter in "wait mode".

On mx35, the LPM field on mx35 is also at 0 after reset, which corresponds
to "run mode" instead of "wait mode".

Instead of relying on the reset value of LPM to set the low power mode for
WFI, configure mx31 and mx35 to run in "wait mode"

Uwe Kleine-König 87514fced7 ARM: imx/mm-imx3: conditionally compile i.MX31 and i.MX35 code
This fixes building a kernel for only one of the two SOCs. Without this
patch an i.MX31 only build fails with:

	arch/arm/mach-imx/built-in.o: In function `imx35_init_early':
	mach-bug.c:(.init.text+0x2c): undefined reference to `mxc_iomux_v3_init'
	arch/arm/mach-imx/built-in.o: In function `imx35_soc_init':
	mach-bug.c:(.init.text+0xe4): undefined reference to `mx35_revision'

Shawn Guo 8c6d8319ec arm/imx: remove imx_idle hook and use pm_idle instead
The patch removes imx_idle hook and use pm_idle instead to get imx
arch_idle prepared for the cleanup.  It's suggested by Russel King
as below.

> The final removal of mach/system.h depends on getting rid of the arch_idle
> thing.  While going through these headers, I was dismayed to find these:
>
> arch/arm/mach-s3c2410/include/mach/system.h:void (*s3c24xx_idle)(void);
> arch/arm/plat-mxc/include/mach/system.h:extern void (*imx_idle)(void);
>
> when we have a perfectly good pm_idle hook already in place - so there's
> no excuse for these especially when other platforms are already using
> pm_idle to hook their platform specific idle function into.  This is
> something that better be gone at the next merge window!

Shawn Guo f548897ffc arm/imx: remove cpu_is_xxx() check from __imx_ioremap()
This patch adds an ioremap hook imx_ioremap to be called in
__imx_ioremap().  Any soc that needs a customized ioremap other
than __arm_ioremap() can set up this hook in soc specific call.

Shawn Guo 41e7daf27a arm/imx: remove cpu_is_xxx() from arch_idle()
This patch adds an idle hook imx_idle to be called in arch_idle().
Any soc that needs a customized idle implementation other than
cpu_do_idle() can set up this hook in soc specific call.

Shawn Guo ddd5f51bf6 arm/imx: change mxc_init_l2x0() to an imx31/35 specific call
The mxc_init_l2x0() should really be an imx31/35 specific call.
The patch removes early_initcall from mxc_init_l2x0() and get imx31
and imx35 soc specific function calls mxc_init_l2x0(), so that it's
not necessarily to be called for all imx socs when we build single
image for multiple imx socs.

Thus the function can be renamed to imx3_init_l2x0() and put into
mm-imx3.c.  It also changes the return type from integer to void.
From what I see, the integer was picked just to satisfy early_initcall
prototype.

With the patch 'ARM: l2x0: add empty l2x0_of_init' applied, the code
compiles even without CONFIG_CACHE_L2X0 enabled.

Shawn Guo 742b6c6f3e arm/imx: rename mm-imx31.c to mm-imx3.c
Since mm-imx31.c now is shared between imx31 and imx35, the patch
renames mm-imx31.c to mm-imx3.c.
