Mark Brown 8942ad89a0 ARM: S3C64XX: Define some additional always off clocks
Add entries to clocks_off for some additional clocks which are not
currently used by any mainline drivers. They default on at power up
but are never actually used so

If these blocks are actually supported some of these bindings would need
to be redone properly, for example hooking up to the muxes that use them,
but that can be done incrementally.

Mark Brown 5d3a21990c ARM: S3C6410: Use device names for both I2C clocks
When the S3C64xx CPUs were converted to clkdev mappings were added for the
I2C controllers on them. On S3C6410 a device name is specified for I2C
controller 1 but not for controller 0 which makes the code less robust as
we'll falsely return the clock for controller 0 if there's an error in the
request for controller 1.

Improve things by registering a device name for controller 0 as well. Due
to the fact that we change the numbering for controller 0 depending on if
we've registered controller 1 this requires an ifdef to choose the name.

Arnd Bergmann a07613a54d Merge branch 'samsung/dt' into samsung/cleanup
Conflicts:
	arch/arm/mach-s3c64xx/Makefile
	arch/arm/mach-s5pc100/Makefile
	arch/arm/mach-s5pv210/Makefile

Pull in previously resolved conflicts:

The Makefiles were reorganized in the "rmk/restart" series and modified
in the "samsung/cleanup series". This also pulls in the other conflict
resolutions from the restart series against the samsung/dt series.

Kukjin Kim b024043b6d ARM: 7245/1: S3C64XX: introduce arch/arm/mach-s3c64xx/common.[ch]
This patch introduces common.[ch] which are used only in the
arch/arm/mach-s3c64xx/ directory. The common.c file merges
the cpu.c, irq.c and irq-eint.c which are used commonly on
S3C64XX SoCs and the common.h file replaces with plat/s3c6400.h
and plat/s3c6410.h files.
