I don't think that's needed. Parents of deinterlace clock are pll-periph0 and 
pll-periph1 which both have fixed clock and thus deinterlace clock will never 
be changed. I just set it to same frequency as it is set in BSP driver. I 
think it works with 600 MHz too, but that's overkill.

Best regards,
