Thanks for applying this series to clk-next, but I wonder if we
shouldn't try to get this merged in 3.17 (in order to avoid back-porting
these fixes to 3.17 stable branch).

I know I said it shouldn't impact that much users, but IMHO we
shouldn't rely on this assumption.

Let me know if you're okay to take these patches in clk-fixes, because
this patch [1] needs to be applied first (I guess Nicolas will take it
through his -fixes branch).

Best Regards,

Boris
