Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is
in the gpio banks range is reversed. Thus the function returns NULL for valid
pins and the gpio chip if its not valid.
As a result gpio states are not saved/restored properly during suspend/resume.

The <mach/regs-gpio.h> really does not need the input and output
pin configurations as these are standard and have a generic

be phased out soon).
The following sed was applied to remove the lines:
sed -i~ -e '/S3C2410_GP[A-Z][0-9]*_\INP/d' \
-e '/S3C2410_GP[A-Z][0-9]*_\OUTP/d' \

Move all the gpio functions out of <mach/hardware.h> as
this file is for defining the generic IO base addresses
for the kernel IO calls.
Make a new header <mach/gpio-fns.h> to take this and
include it via the chain from <linux/gpio.h> which is
what most of these files should be using (and will be
changed as soon as possible).
Note, this does make minor changes to some drivers but
should not mess up any pending merges.

The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are
very rare and are taking up large amounts of space in the
regs-gpio.h header.
The GPIO layer has had generic input and out defines called
S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work
for all S3C24XX GPIOs.
Do the following replacements:
S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT
S3C2410_GP[A-Z][0-9]*_\INP => /S3C2410_GPIO_INPUT
S3C2410_GPA[0-9]*_OUT => S3C2410_GPIO_OUTPUT
to remove any usages of these and prepare the header for
the removal of these.
The following command was used to acheive this:
find . -type f -writable ! -name regs-gpio.h ! -name "*~" | xargs sed -i~ -e 's/S3C2410_GP[A-Z][0-9]*_\OUTP/S3C2410_GPIO_OUTPUT/g' -e 's/S3C2410_GP[A-Z][0-9]*_\INP/S3C2410_GPIO_INPUT/g' -e 's/S3C2410_GPA[0-9]*_OUT/S3C2410_GPIO_OUTPUT/g'

The platform data for the i2c-s3c2410 driver used to allow a min,
max and desired frequency for the I2C bus. This patch reduces it
to simply a desired frequency ceiling and corrects all the uses
of the platform data appropriately.
This means, for example, that on a system with a 66MHz fclk, a
request for 100KHz will achieve 65KHz which is safe and
acceptable, rather than 378KHz which it would have achieved
without this change.

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not. There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().
This patch fixes things to pass this string to arch_reset(). This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.
