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

Add checks for clk_set_rate() and ensure that we do not allow set_rate
to be called for a clock that does not have it defined. Add default
methods for fclk, hclk, pclk and mpll.

The following patch and script moves the arch/arm/mach-s3c2410
directory into arch/arm/plat-s3c24xx for the generic core code
and inti arch/arm/mach-s3c{cpu} for the cpu/machine support files

Include directory include/asm-arm/plat-s3c24xx is added for the

Patch from Ben Dooks

The current S3C2412 support has moved to using
S3C24XX_DCLKCON unless the specific DCLKCON is
required (S3C2412_DCLKCON or S3C2410_DKCLKCON)

Move the few places using S3C2410_DCLKCON to
S3C24XX_DCLKCON

Patch from Ben Dooks

Add a get_rate call to allow an given clock
to over-ride the clk_get_rate() call.

This provides support for clocks which rely on
division of their parent to correctly report
their frequency when the parent can also change.

Split the s3c2410 specific clocks from the core
clock code, as part of the work to support more
of the Samsung line of SoCs.

The patch does not use the sysdev mechanism as
the clocks are needed for the timer init, which
is very early in the kernel init sequence.

Move to using an enable count for the shared clocks
and protect the clock system using a mutex instead
of just disabling IRQs during the clock update.

Since there is little more code in the path for

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
