Ben Dooks ad14ff3749 [ARM] S3C: Fix sparse warning from missing 's3c_device_hwmon'
Fix the following sparse warning due to s3c_device_hwmon being
missing from <plat/devs.h>

devs.c:380:24: warning: symbol 's3c_device_hwmon' was not declared. Should it be static?

Daniel Silverstone c564e6ae6c i2c-s3c2410: Simplify bus frequency calculation
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.

Ben Dooks fff94cd9f5 [ARM] S3C: Tidy sleep code path to fix call flow
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.

Ben Dooks aa8aba6944 [ARM] S3C: Do not kmalloc/kfree during inner suspend code.
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.

Move the allocation and free to points in the suspend and resume
process where they can call a function that might-sleep.

Change the way the UART state is saved over suspend to allow the s3c64xx

to the UART clocks. This will also allow us to save the UDIVSLOT register

Move to using a structure for the UART use the extant Kconfig configuration
specifying the number of UARTs.

Ben Dooks 9d325f2341 [ARM] S3C: Update time initialisation to fix S3C64XX time problems
The S3C64XX timer is running at the wrong rate due to the
assumptions made in the timer initialisation about the way
the pwm dividers work. This means that time on the S3C64XX
runs twice as fast as it should.

Fix the problem by moving to using the clk framework to setup
the pwm timer clock muxes, as the pwm-clock code has all the
necessary knowledge of how the timer clock inputs are routed.
