7de40c216c [ARM] S3C: Remove cpufreq warnings for unset serial information
As noted by Russell King, do not print any warnings if the
uinfo or tty fields are not set when a CPU frequency change
is sent.

bdd4915a9f [ARM] S3C: Update CONFIG_SERIAL_SAMSUNG_UARTS handling
Fix the usage of CONFIG_SERIAL_SAMSUNG_UARTS in several places
in the kernel where it had been missed. This finishes fixing a
long standing issue where S3C2443 and S3C64XX could not use the
4th UART

b73c289cc9 [ARM] S3C: Update serial driver IRQ handling
The S3C64XX code changes the order of the serial
interrupts, so change the registration process to
pickup the extra IRQ resources.

1d4bab0824 [ARM] S3C24A0: Serial port definitions and driver support.
Add serial support for S3C24A0, based on current S3C2410
UART driver. It adds necessary new defines in regs-serial.h
for S3C24A0 and the code to support this device in
drivers/serial/s3c24a0.c

a2b7ba9ca4 [ARM] S3C24XX: Move files out of include/asm-arm/plat-s3c*
First move of items out of include/asm-arm/plat-s3c* to their
new homes under arch/arm/plat-s3c/include/plat and
arch/arm/plat-s3c24xx/include/plat directories.

Note, we have to create a dummy arch/arm/plat-s3c/Makefile to
allow us to add arch/arm/plat-s3c/include/plat to the path.

be50972935 [ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

I missed the cpm_uart one. Thanks to Kumar Gala for reporting it. A double
check found samsung also needed fixing up.

b497549a03 [ARM] S3C24XX: Split serial driver into core and per-cpu drivers
The S3C2410 serial driver in drivers/serial/s3c2410.c has been
growing bigger with the addition of more variants of this hardware
with the growing Samsung SoCs range. As such, it would be
easier to split this code up into a core and per-cpu drivers to
make driver addition easier, and the core smaller.
