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
