Merge branch 'next/cam-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/soc

From Kukjin Kim:
Just adding camif gpio setup and clkdev.

* 'next/cam-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: S3C24XX: Add clkdev entry for camif-upll clock
  ARM: SAMSUNG: Add s3c24xx/s3c64xx CAMIF GPIO setup helpers
  + Linux 3.7-rc6

Conflicts due to the 3.7-rc6 sync: arch/arm/mach-highbank/system.c
include/linux/clk-provider.h, resolved as in other branches.
