ARM: s3c24xx: Set ARCH_NR_GPIOS according to the selected SoC types.
Currently the code in gpiolib.c tries to register GPIO BANKA-BANKM.
ARCH_NR_GPIOS on the other hand is set only to 256, which would be the
equivalent of BANKA-BANKH. Thus the registration of all other banks will fail.
This patch fixes this by setting S3C_GPIO_END according to the selected SoC
types. S3C_GPIO_END is set to the maximum of the number of GPIOs over all
selected SoC types. Thus it is ensured that memory is not wasted if support for
SoCs with higher GPIO numbers is not built-in. When registering the bank it is
made sure that banks which are outside of that range are not even tried to be
registered. Otherwise there would be problems with configs where
CONFIG_S3C24XX_GPIO_EXTRA is set to a non zero value.

s3c24xx: Fix level irqs on external interrupts.
Although the external interrupts support level and edge triggered irqs their
handler is currently always set to handle_edge_irq().
While being technically wrong for a level triggered irq to be handled by
handle_edge_irq() it will cause serious problems in combination with a oneshot
irq. handle_edge_irq() will unmask the irq immediately and as a result the irq
will be triggered again before the threaded irq handler had a chance to run and
clear the irq source.
Thus level triggered irqs should be handled by handle_level_irq.
According to the specs the irq controller will remember if an irq has been
triggered while it had been masked and will issue it when the irq gets
unmasked. Thus it is sufficient to use handle_level_irq() for edge triggered
irqs as well. Hence handle_level_irq() can always be used for external
interrupts.

This patch adds a flag to the s3c2410_nand platform data, which configures
whether hardware ecc is used for that chip.
Currently hardware ecc is used if it was compiled into the kernel. But if you
want to build a kernel which runs on multiple devices you might have a
configuration where you have devices which require hw ecc as well as devices
which want software ecc.

mmc: add none blocking mmc request function
Previously there has only been one function mmc_wait_for_req
to start and wait for a request. This patch adds
* mmc_start_req - starts a request wihtout waiting
* mmc_wait_for_req_done - waits until request is done
* mmc_pre_req - asks the host driver to prepare for the next job
* mmc_post_req - asks the host driver to clean up after a completed job
The intention is to use pre_req() and post_req() to do cache maintenance
while a request is active. pre_req() can be called while a request is active
to minimize latency to start next job. post_req() can be used after the next
job is started to clean up the request. This will minimize the host driver
request end latency. post_req() is typically used before ending the block
request and handing over the buffer to the block layer.
Add a host-private member in mmc_data to be used by
pre_req to mark the data. The host driver will then
check this mark to see if the data is prepared or not.

mmc: add handling for two parallel block requests in issue_rw_rq
Change mmc_blk_issue_rw_rq() to become asynchronous.
The execution flow looks like this:
The mmc-queue calls issue_rw_rq(), which sends the request
to the host and returns back to the mmc-queue. The mmc-queue calls
isuue_rw_rq() again with a new request. This new request is prepared,
in isuue_rw_rq(), then it waits for the active request to complete before
pushing it to the host. When to mmc-queue is empty it will call
isuue_rw_rq() with req=NULL to finish off the active request
without starting a new request.

lis302dl: use ABS events rather then REL events
AG: there's some more rationale for changing this here
http://lists.openmoko.org/pipermail/openmoko-kernel/2009-March/009387.html
Change accelerometers to use ABS events rather than REL events.
[Obviously if this patch is accepted we need to tell developers about
it. I have a number of other improvements to the accelerometers I
hope to deliver over the next couple of weeks. They will have minimal
or zero disruption to current code. ]
REL events should be used when there is no absolute reference, and
only changes are meaningful. The classic example is a "mouse" where
the absolute position of the device is not measurable and not
particularly meaning, but change in position from one time to the next
is interesting.
With REL events, a value of '0' is not reported, as 'not change' is
not interesting.
With REL events, the expectation is that successive values will be
eventually summed (possibly with acceleration and clipping
adjustments) to get a usable value.
ABS events should be used when there is an absolute references against
which things that be measured.
With ABS events, the 'current value' is meaningful and can be read
(EVIOCGABS).
With ABS events, the value '0' is very meaningful and is reported.
However if consecutive values are the same, the value is only reported
once.
ABS events can be used as-is or compared with previous events to get
some measure of change.
An obvious example is a touchscreen where each measure in
independently meaningful.
Acceleration is an absolute value as it is measuring against a frame
of reference. '0' acceleration is just as meaningful as any other
value, and finding the 'current' acceleration is each direction is a
potentially useful thing to do.
The Freerunner accelerometers currently report REL events. This is
wrong. So this patch changes them to report ABS events.
With this patch, the min/max/level/fuzz values are left at zero. It
might be useful to make use of these in a subsequent patch.
min/max/level can be used to calibrate the accelerometers if accuracy
is important.
fuzz could possibly be used in conjunction with the 'threshold' sysfs
value to get less frequent, lower-precision reports.
This may well break some applications that read accelerometer data.
This cannot be helped, but it is quite easy to write code that copes
with the incorrect EV_REL events as well as the more correct and
useful EV_ABS events.
