Merge tag 's3c24xx-clk' of http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup
Merge "Samsung S3C24XX updates for 3.16" from Kukjin Kim: Samsung S3C24XX to use the common clock framework - S3C2412, S3C2413, S3C2416 and S3C2443 to use CCF - S3C2410, S3C2440, S3C2442 to use CCF - Remove legacy samsung clock from mach-s3c24xx/ - Some of them are missed from previous pull-request - Clock related sutff got ack from Mike and Tomasz - Created the last commit due to missing changes during re-sorting because this branch is provided as a base to samsung clk tree. * tag 's3c24xx-clk' of http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: (23 commits) ARM: S3C24XX: fix merge conflict ARM: S3C24XX: remove SAMSUNG_CLOCK remnants after ccf conversion ARM: S3C24XX: remove legacy clock code ARM: S3C24XX: convert s3c2410 to common clock framework ARM: S3C24XX: convert s3c2440 and s3c2442 to common clock framework ARM: S3C24XX: add platform code for conversion to the common clock framework clk: samsung: add clock controller driver for s3c2410, s3c2440 and s3c2442 dt-bindings: add documentation for s3c2410 clock controller ARM: S3C24XX: enable usage of common dclk if common clock framework is enabled clk: samsung: add clock driver for external clock outputs ARM: S3C24XX: cpufreq-utils: don't write raw values to MPLLCON when using ccf ARM: S3C24XX: convert s3c2412 to common clock framework clk: samsung: add clock controller driver for s3c2412 dt-bindings: add documentation for s3c2412 clock controller clk: samsung: add plls used by the early s3c24xx cpus ARM: S3C24XX: only store clock registers when old clock code is active ARM: S3C24XX: Convert s3c2416 and s3c2443 to common clock framework ARM: dts: add clock data for s3c2416 ARM: S3C24XX: prevent conflicts between ccf and non-ccf s3c24xx-socs clk: samsung: add clock-driver for s3c2416, s3c2443 and s3c2450 ...
