This patch improves the serial port communication quality
of port YC401 on the KFR2R09 board. With this fix serial
console is fine at 115200 - up and down keys now work as
expected. Thanks to Hirohide Yamasaki for this fix.

This file breaks out the SuperH PFC code from
arch/sh/kernel/gpio.c + arch/sh/include/asm/gpio.h
to drivers/sh/pfc.c + include/linux/sh_pfc.h.
Similar to the INTC stuff. The non-SuperH specific
file location makes it possible to share the code
between multiple architectures.

commit 746357d (x86: Prevent GCC 4.4.x (pentium-mmx et al) function
prologue wreckage) uses -mtune=generic to work around the function
prologue problem with mcount on -march=pentium-mmx and others.
Jakub pointed out that we can use -maccumulate-outgoing-args instead
which is selected by -mtune=generic and prevents the problem without
losing the -march specific optimizations.

Adds core support for the ST-Ericsson U8500
platform. It supports memory mappings, binds to
the existing modules like GIC, SCU, TWD and
local timers and sets up the infrastructure for
the secondary core.

Introduce the plat-nomadik folder for ST-Ericsson
machines including the existing nomadik 8815 architecture.
This also moves the existing MTU (MultiTimerUnit)
of nomadik 8815 to the proposed plat-nomadik and adds
HAS_MTU. The patch has been re-based to 2.6.32-rc6

This add the pda-power platform device to collie.
|
|
Only the parts used for collie_battery are converted.
The rest will be cleaned up later.
|
|
The old access methods to the gpios will be removed when
all users has been converted. (mainly ucb1x00-ts)
|
|
The function can't be used for static initialisations so
convert them to macros.

Andrew complained rightly that the WARN_ON in hpet_next_event() is
confusing and the code comment not really helpful.
Change it to WARN_ONCE and print the reason in clear text. Change the
comment to explain what kind of hardware wreckage we deal with.

The data that was stored in this table is now available in
dev->archdata.iommu. So this table is not longer necessary.

removes it from the code.

This patch introduces a list to each protection domain which

This patch adds a reference count to each device to count
how often the device was bound to that domain. This is
important for single devices that act as an alias for a
number of others. These devices must stay bound to their
domains until all devices that alias to it are unbound from
the same domain.

With the previous changes the get_device_resources function
can be simplified even more. The only important information
for the callers is the protection domain.
This patch renames the function to get_domain() and let it
only return the protection domain for a device.

If there is no domain associated to a device yet and the
device has an alias device which already has a domain, the
original device needs to have the same domain as the alias
device.
This patch changes domain_for_device to handle this
situation and directly assigns the alias device domain to
the device in this situation.
