e856bb1f8d ARM: SAMSUNG: Remove empty gpio-core.h and use central plat/gpio-core.h
Rename mach-s3c2410/include/mach/gpio-core.h to mach/gpio-track.h so that
it can be included by <plat/gpio-core.h> when needed.

Eliminate all other empty gpio-core.h files and just include the
<plat/gpio-core.h> as necessary.

0a6361316d ARM: SAMSUNG: Make UART device code common
Move s3c24xx_uart_devs, s3c24xx_uart_src and the platform devices to a
common entry in plat-samsung since they are the same in all the current
implementations.

a0de298a0e ARM: S5PC1XX: Register pd0 and hd0 clocks, remove unecessary dummy_enable
The clk_hd0 and clk_pd0 where given a local dummy_enable call due to
not being registered with the clock code, which they really should have
been. Register these two clocks and remove the clk_dummy_enable as this
is done by the default clock registration code.

35accd2f66 ARM: S5PC1XX: Remove definitions deleted by previous clksrc changes
Remove the definitions we've deleted in the previous updates to the
clksrc_clk for arch/arm/plat-s5pc1xx/include/plat/regs-clock.h.

Added comments about the removal to the clock header since we only need
these defines in one place (and they've now been removed there) we get
rid of them from the header.

c837e88cf9 ARM: S5PC1XX: Change clksrc_clks to use array of clocks
Remove the individual 'struct clksrc_clks' and place them into an array
so that we can simply use s3c_register_clksrcs to register tham all in one
go.

Since the spdif clock relies on the audio clock, move the audio clocks
into their own arrary.

Thanks to  Marek Szyprowski for testing and pointing out the four clocks
what where missed from the clock list.

4542646814 ARM: S5PC1XX: Move to using generic clksrc_clk for clock code
Remove the copy of the old s3c64xx struct clksrc_clk and use the new one
in plat-samsung. This eliminates a bug in the set_parent() call where it
failed to set the clk->parent after sucesfully updating the clock.

The script that was used to automate much of the process will be supplied
seperately.

b3bf41be06 ARM: SAMSUNG: Reduce size of struct clk.
Reduce the size of struct clk by 12 bytes and make defining clocks with
common implementation functions easier by moving the set_rate, get_rate,
round_rate and set_parent calls into a new structure called 'struct clk_ops'
and using that instead.

This change does make a few clocks larger as they need their own clk_ops,
but this is outweighed by the number of clocks with either no ops or having
a common set of ops.

Update all the users of this.

S5PC100 is a new SoC with ARM coretex-A8 and numerous peripherals. This SoC is
successor of S3C64XX. S5PC100 has peripherals which are still similar to S3C
families so some drivers in "arch/arm/plat-s3c" can be shared. S5PC100 specific
drivers will be added in "arch/arm/plat-s5pcxx" or "arch/arm/mach-s5pc100"

S5PC100 has 3 VICs(Vectored Interrupt Controller). The VICs come from S3C64xx
series, so the driver source code can be shared with S3C families. The S5PC100
has 3 VICs while S3C64xx has only 2.
