Convert omap_wdt to new watchdog core. On OMAP boards, there are usually
multiple watchdogs. Since the new watchdog core supports multiple
watchdogs, all watchdog drivers used on OMAP should be converted.
The legacy watchdog device node is still created, so this should not
break existing users.

With device tree support in place, we should not use IMX_HAVE_PLATFORM_IMX2_WDT
as a dependency for selecting the imx2_wdt driver.
Use ARCH_MXC symbol instead, so that the driver can be even selected by a device-tree
only SoC, such as i.MX6.

As a first step towards migrating davinci platforms to use common clock
framework, replace all instances of clk_enable() with clk_prepare_enable()
and clk_disable() with clk_disable_unprepare(). Until the platform is
switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just
adds a might_sleep() call and would work without any issues.
This will make it easy later to switch to common clk based implementation
of clk driver from DaVinci specific driver.

Clk_prepare_enable and clk_disable_unprepare combine clk_prepare and
clk_enable, and clk_disable and clk_unprepare. They make the code more
concise, and ensure that clk_unprepare is called when clk_enable fails.
A simplified version of the semantic patch that introduces calls to these
functions is as follows: (http://coccinelle.lip6.fr/)
// <smpl>

Second set of OMAP PRCM cleanups for 3.8.
These patches remove the use of omap_prcm_get_reset_sources() from the
OMAP watchdog driver, and remove mach-omap2/prcm.c and
plat-omap/include/plat/prcm.h.
Basic test logs for this branch on top of Tony's cleanup-prcm branch
at commit 7fc54fd308 are here:
http://www.pwsan.com/omap/testlogs/prcm_cleanup_b_3.8/20121108151646/
However, cleanup-prcm at 7fc54fd3 does not include some fixes
that are needed for a successful test. With several reverts,
fixes, and workarounds applied, the following test logs were
obtained:
http://www.pwsan.com/omap/testlogs/TEST_prcm_cleanup_b_3.8/20121108151930/
which indicate that the series tests cleanly.
This second pull request updates one of the patches which broke
with rmk's allnoconfigs, and also updates the tag description to
indicate that 7fc54fd3 is building cleanly here.

Previously the OMAP watchdog driver used a non-standard way to report
the chip reset source via the GETBOOTSTATUS ioctl. This patch
converts the driver to use the standard WDIOF_* flags for this
purpose.
This patch may break existing userspace code that uses the existing
non-standard data format returned by the OMAP watchdog driver's
GETBOOTSTATUS ioctl. To fetch detailed reset source information,
userspace code will need to retrieve it directly from the CGRM or PRM
drivers when those are completed.
Previously, to fetch the reset source, the driver either read a
register outside the watchdog IP block (OMAP1), or called a function
exported directly from arch/arm/mach-omap2. Both approaches are
broken. This patch also converts the driver to use a platform_data
function pointer. This approach is temporary, and is due to the lack
of drivers for the OMAP16xx+ Clock Generation and Reset Management IP
block and the OMAP2+ Power and Reset Management IP block. Once
drivers are available for those IP blocks, the watchdog driver can be
converted to call exported functions from those drivers directly.
At that point, the platform_data function pointer can be removed.
In the short term, this patch is needed to allow the PRM code to be
removed from arch/arm/mach-omap2 (it is being moved to a driver).
This version integrates a fix from Jon Hunter <jon-hunter@ti.com>
that avoids a NULL pointer dereference in a DT-only boot, and integrates
a patch commit message fix from Felipe Balbi <balbi@ti.com>.

As usual we have a few new drivers:
- TI LP8788
- TI OMAP USB TLL
- Maxim MAX8907
- SMSC ECE1099
- Dialog Semiconductor DA9055
- A simpler syscon driver that allow us to get rid of the anatop one.
Drivers are also gradually getting Device Tree and IRQ domain support.
The following drivers got DT support:
- palmas, 88pm860x, tc3589x and twl4030-audio
And those ones now use the IRQ domain APIs:
- 88pm860x, tc3589x, db8500_prcmu
Also some other interesting changes:
- Intel's ICH LPC now supports Lynx Point
- TI's twl4030-audio added a GPO child
- tps6527 enabled its backlight subdevice
- The twl6030 pwm driver moved to the new PWM subsystem
And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
ab8500, wm8994, wm5110, max8907 and the tps65xxx family.

This is a large branch that contains a handful of different cleanups:
- Fixing up the I/O space remapping on PCI on ARM. This is a series
from Rob Herring that restructures how all pci devices allocate I/O
space, and it's part of the work to allow multiplatform kernels.
- A number of cleanup series for OMAP, moving and removing some
headers, sparse irq rework and in general preparation for
multiplatform.
- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used with
a mainline kernel. We have not been able to find anyone interested
in keeping it around in the kernel.
- Removal of the legacy dmaengine driver on tegra

Convert the ColdFire 54xx CPU General Timer register address definitions to
include the MCF_MBAR peripheral region offset. This makes them consistent
with all other 54xx address register definitions (in m54xxsim.h).
The goal is to reduce different definitions used (some including offsets and
others not) causing bugs when used incorrectly.

dependencies to mach/hardware.h. These help moving
things towards ARM single zImage support.

From "Uwe Kleine-Knig" <u.kleine-koenig@pengutronix.de>:
this is the 2nd version of this series whose goal is to make struct
of_device_id.data const. Conceptually a driver must not modify the data
contained there so making it const is the right thing.
v1 of this series was sent with Message-id:
1342182734-321-1-git-send-email-y. Changes since then are:
- powerpc fixes
- several new consts that were found by Arnd that are possible after
patch 19.
Arnd suggested to take this series via arm-soc late for 3.6 in one go
because patch 19 depends on the former patches but is a precondition to
the latter and it fixes a few warnings. So getting it in via the
respective maintainer trees would need a much bigger coordination
effort. That means I prefer getting Acks over you taking the patch.
Vinod Koul already took
dmaengine: at_hdmac: add a few const qualifiers
that is in next-20120723 as 7fd63ccdad now. Vinod, I don't follow your
pull requests, but assuming you didn't let it already pull for 3.6 I
suggest you drop it from your queue and I just take your Ack.
This series was build tested for arm (all defconfigs) and powerpc (all
defconfigs and an allyesconfig) and grep didn't find more issues. As
before it introduces a warning in drivers/regulator/twl-regulator.c.
This driver does modify its .of_match_table when a device is bound which
doesn't fits the concept of independant devices. Arnd noticed another
new warning in drivers/scsi/qlogicpti.c that isn't that easy to resolve,
because the pointer to (now) const data is passed as first argument to
scsi_host_alloc. To fix that properly struct Scsi_Host.hostt needs to
get a const, too. Alternatively I could introduce a cast removing the
const, but I don't like that.

As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.
Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.
The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.
Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.
Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.
Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.
While at it, also sort some of the includes in the standard way.

Commit 70adc3f32a
"ARM: ks8695: merge the timer header into the timer driver"
accidentally broke the ks8695 watchdog since it was using
the timer registers in watchdog mode.
Perform the same operation here: push the registers down
into the driver, so it is self-contained, and we can keep
depopulating the <mach/*> namespace.

kdump can be interrupted by watchdog timer when the timer is left
activated on the crash kernel. Changed the hpwdt driver to disable
watchdog timer at boot-time. This assures that watchdog timer is
disabled until /dev/watchdog is opened, and prevents watchdog timer
to be left running on the crash kernel.
