Sascha:

Here's a a bunch of fixes for "clk: at91: Port at91 DT clock code"

 - arch/arm/Kconfig to prevent breaking the build for AT91
   targets that don't use DT based clock

 - arch/arm/mach-at91/Makefile is need to avoid building non DT clock
   code for targets that do use DT (I accidentaly put put that change
   into a differnet, not yet submitted, patch by mistake)

 - The rest is whitespace damage removal

Let me know if it'd be more convenient to drop the original patch and
re-spin a v2 of it.

Thanks,
Andrey Smirnov
