Hi Geert, Thank you for your review! On Tue, Dec 3, 2019, Geert Uytterhoeven wrote: > > + unsigned long flags; > > = 0 here... > > > > + flags = 0; > > ... instead of here? That was my first thought too...and it was wrong. If of_clk_detect_critical does NOT detect a critical clock, it does not touch flags at all. And since it is a loop, what you get is after the first clock is marked as CRITICAL, all the remaining clocks also get marked CRITICAL. In this case, both spibsc0 and spibsc1 get marked critical. That's why I have to reset it for each loop. Chris
