Here's the big TTY/serial driver pull request for the 3.5-rc1 merge window.
Nothing major in here, just lots of incremental changes from Alan and
Jiri reworking some tty core things to behave better and to get a more
solid grasp on some of the nasty tty locking issues.
There are a few tty and serial driver updates in here as well.
All of this has been in the linux-next releases for a while with no problems.

While we generally attempt to get rid of board specific files and replace
them with device tree based descriptions, a lot of platforms have not
come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination of
DT and board file contents in multiple cases.
pxa/mmp and imx are extending support for existing board files but not
adding new ones.

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.

HIGMEM support in kernel is quite mature now and we have boards
like ZOOM, PANDA, SDP where 1 GB memories are installed. With
HIGHMEM disabled not all of the 1GB of RAM (only ~700MB) can be
accessed. Hence, enable HIGMEM to make use of the entire memory.
On the boards which doesn't have more than 768 MB memory, all
the memory is directly mapped in "lowmem" and highmem isn't
exercised. Hence, there should be no impact by enabling HIGHMEM
for boards that do not need it.

Each irq_chip for the main interrupt controller has offsets set for irq
masking registers, which added to respective base results in a pointer
to appropriate hardware register. However this is not correct for
INTC_CONTROL as there is only one INTC_CONTROL register. This does not
cause problems because generic ack code is never called, but remove
this assignment to avoid confusion.

this is the series of the 4 patches adding device tree support to i2c-pnx
(used by LPC32xx) that Wolfram Sang already applied to the i2c subsystem.
Since both drivers/i2c/ and mach-lpc32xx are touched here, there will
probably be conflicts that you need to be aware of.
I'm posting this again for arm-soc since the actual mach-lpc32xx specific
DT conversion builds upon those changes (see next pull request), especially
in arch/arm/mach-lpc32xx/common.c.
Wolfram already gave permission to merge this via arm-soc, but please
coordinate and tell me if I can help resolving this.
Further, this implicitly updates the next/dt branch to v3.4-rc4, which
causes a trivial conflict from a change in one branch in code that
gets removed in another.

This is a rebased version of parts of
git://git.stlinux.com/spear/linux-2.6.git spear-v3.5
which was accidentally based on the linux-next tree and mixed too
many different things. The pinctrl related changes from the same
branch are now in the spear/pinctrl branch of arm-soc.
There are a few non-DT cleanups mixed in here, but fundamentally
it's all related to the DT conversion.

In preparation for device tree, this patch changes how the DSI pins are
configured. The current configuration method is only doable with board
files and the configuration data is OMAP specific.
This patch moves the configuration data to the panel's platform data,
and the data can easily be given via DT in the future. The configuration
data format is also changed to a generic one which should be suitable
for all platforms.
The new format is an array of pin numbers, where the array items start
from clock + and -, then data1 + and -, and so on. For example:
{
0, // pin num for clock lane +
1, // pin num for clock lane -
2, // pin num for data1 lane +
3, // pin num for data1 lane -
...
}
The pin numbers are translated by the DSI driver and used to configure
the hardware appropriately.

Without runtime PM enabled, hwmod needs to leave all IP blocks in an
enabled state by default so any driver access to the HW will succeed.
This is accomplished by seting the postsetup_state to enabled for all
hwmods during init when runtime PM is disabled.
Currently, we have a special case for WDT in that its postsetup_state
is always set to disabled. This is done so that the WDT is disabled
and the timer is disarmed at boot in case there is no WDT driver.
This also means that when runtime PM is disabled, if a WDT driver *is*
built in the kernel, the kernel will crash on the first access to the
WDT hardware.
We can't simply leave the WDT module enabled, because the timer is
armed by default after reset. That means that if there is no WDT
driver initialzed or loaded before the timer expires, the kernel will
reboot.
To fix this, a custom reset method is added to the watchdog class of
omap_hwmod. This method will *always* disarm the timer after hwmod
reset. The WDT timer then will only be rearmed when/if the driver is
loaded for the WDT. With the timer disarmed by default, we no longer
need a special-case for the postsetup_state of WDT during init, so it
is removed.
Any platforms wishing to ensure the watchdog remains armed across the
entire boot boot can simply disable the reset-on-init feature of the
watchdog hwmod using omap_hwmod_no_setup_reset().
Tested on 3530/Overo, 4430/Panda.
NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as
documented in the TRM (and what happens on OMAP3.) I noticed this
because testing the HWMOD_INIT_NO_RESET feature with no driver loaded,
I expected a reboot part way through the boot, but did not see a
reboot. Adding some debug to read the counter, I verified that right
after OCP softreset, the counter is not firing. After writing the
magic start sequence, the timer starts counting. This means that the
timer disarm sequence added here does not seem to be needed for 4430,
but is technically the correct way to ensure the timer is disarmed, so
it is left in for OMAP4.
Special thanks to Paul Walmsley for helping brainstorm ideas to fix
this problem.
