Yes, I know ;) But this is slightly different: In the end it disables 
the complete clk_disable_unused() call, i.e. for all unused clocks.

I'd like to set the flag CLK_IGNORE_UNUSED for just one clock. I.e. I 
want to set a flag for an i.MX6 clock, and I want to set it only for 
one clock.

What's the preferred way to do this?

Best regards
