Hello,

these patches add the possibility of setting constraints on the frequency of
clocks. In contrast to my two previous approaches, this is accomplished with
per-user clocks, but without requiring changes to existing drivers. An
exception to the latter are a few boards in mach-omap2, which still register
their clocks statically and thus had to be changed to initialize struct
clk_core. Hopefully the whole of clk-private.h can be removed once those boards
have been converted to initialize their clocks with DTS files.

The first patch implements per-user clocks properly, and the second adds the
constraint API.

Thanks,

Tomeu
