[PATCH 00/12] ARM: S3C24XX: convert s3c2410, s3c2440 s3c2442 to common clock framework

This series converts the earliest s3c socs to use a clock driver based on the
common clock framework instead of the old Samsung clock implementation.

The only obstacle I found was the configuration of the clkout outputs in
the different machines. As I lack hardware test and knowledge on what is
expected there, somebody with interest in these machines will have to
step up to implement the clkout configuration
This can for example be done in the machine_init function after
the platform-devices (and thus the dclk-device) are populated.

This leaves the s3c2412 soc to be converted, as it has yet another different
clock tree.

Tested on an Openmoko Neo Freerunner (S3C2442), but of course more tests
would be really helpful.

Heiko Stuebner (12):
ARM: S3C24XX: cpufreq-utils: don't write raw values to MPLLCON when using ccf
dt-bindings: document s3c24xx controller for external clock output
clk: samsung: add clock driver for external clock outputs
ARM: S3C24XX: enable usage of common dclk if common clock framework is enabled
ARM: S3C24XX: only store clock registers when old clock code is active
clk: samsung: add plls used by the early s3c24xx cpus
dt-bindings: add documentation for s3c2410 clock controller
clk: samsung: add clock controller driver for s3c2410, s3c2440 and s3c2442
ARM: S3C24XX: add platform code for conversion to the common clock framework
ARM: S3C24XX: convert s3c2440 and s3c2442 to common clock framework
ARM: S3C24XX: convert s3c2410 to common clock framework
ARM: S3C24XX: remove legacy clock code
