Sorry Geert, my reply has been cut:

The main problem I see with this proposal is that clk_register_flexgen() is called for several SoCs (STiH407/410/418...). Each of these SoCs have this clock, but maybe STiH407 will need the flag, but not STiH410 and STiH418. So I think the best place to set this information is in DT, where the differentiation is made between the SoCs.
Kind regards, Maxime
