Commit 52da219e9664e537a745877b0efa7cf2b1ff2996 added IIS
platform devices, but these do not build on s3c24xx systems
and the file depends on SND_S3C24XX_SOC, which is selected
for all S3C64XX/S3C24XX systems.
As a quick fix, make the dev-audio.o file depends on
SND_S3C64XX_SOC_I2S instead.

Commit 52da219e9664e537a745877b0efa7cf2b1ff2996 removed
the s3c_device_iis, but didn't replace it with anything
so a number of s3c24xx machines are currently failing
to build.
As a temporary fix, re-instate s3c_device_iis until a
proper replacement can be done for it.

convert callback
This patch allow us to efficiently modify the number of
remaining conversions from the client side. This us useful
when we do not know in advance how many conversions we will
need or when we need to cancel pending conversions.
This change is simple enough to be compatible with existing
code that can just define the new pointer in the callback
and ignore it.
Sample usage:

The s3c24xx_register_clock() function has been doing a test
on clk->owner to see if it is NULL, and then setting itself
as the owner if clk->owner == NULL.
This is not needed, arch/arm/plat-s3c/clock.c cannot be
compiled as a module, and even if it was, it should not be
playing with this field if it being registered from somewhere
else.
The best course of action is to remove this bit of
code completely.

Move the GPIO suspend/resume support inline with the gpiolib support
so that it will work with both the S3C24XX and S3C64XX series.
The s3c_gpio_chip is extended to have a pm callback and a save block
to keep the state of the GPIO over suspend, and the code from the
s3c24xx implementation is added to a new common file.
The suspend process now uses the list of registered chips to go through
saving and restoring each one as appropriate, using the pm callback to
select the appropriate routine depending on the type of control register
present.
This change also means that any additional GPIO added should not require
changes to the PM.

Add support for saving the state of the IRQ registers over suspend.
This requires moving the S3C64XX UART registers into <plat/regs-serial.h>
and adding irq-pm.c which saves the state of all the IRQ registers.
The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and
IRQ_EINT_GROUP registers as it was easier than adding three different
files. Also ensuring that all the registers are restored to the same
state as before suspend is considered to be the best thing to do.
Note, we do not suspend the VIC here, this is done by the VIC driver
itself.

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.

As noted by Russell King, the sleep code path is not
elegant and makes use of leaving items on the stack
between calls.
Change the code that does the following:
if (s3c_cpu_save(regs_save) == 0) {
flush_cache_all();
S3C_PMDBG("preparing to sleep\n");
pm_cpu_sleep();
}
to simply call s3c_cpu_save, and let that do the
necessary calls to quiesce and sleep the system.

The PM CRC checking code kmallocs an area to save a set of
CRC values during suspend. This triggers a warning due to the
call of a function that might sleep whilst the system is not
in a valid state to do so.

process where they can call a function that might-sleep.
