The slow clk block provided by at91sam9260 and derived SoCs should always
have 2 parents.

Hello Mike,
Could you take this fix for the next 3.17 rc ?
Without this fix you won't be able to use programmable clks (the slow
clk is one of the parents of prog clks), and these prog clks are used,
among other things, to provide clks to external audio chips.
No need to backport this fix to previous stable releases, as CCF support
for at91sam9260 (and derived) SoCs only appeared in 3.17.
Best Regards,
Boris
