Hi Thomas,
You can find few comments inline.

Keep in mind that following clocks are common for Exynos4210 and
Exynos4x12. Have you tested this series on a board based on Exynos4212
or 4412 to verify that it does not break the legacy driver? (I would
test it myself, but I am on holidays at the moment.)

This will not work on Exynos4412, because there is no "armclk" added for
this SoC. My suggestion is to simply keep name of the clock as is, move
current "arm_clk" divider to Exynos4x12-specific clocks and register
Exynos4210 CPU clock as "arm_clk".
Best regards,
Tomasz
