How is it possible that you change spread spectrum of some clocks from main Clock Controller, while this device is not a consumer of them? Basically this means that this device does not have these clocks but yet you claim that it needs to configure spread for them! It's contradictory to me and nohing got explained in commit msg about it. I am pretty sure I asked about this alrady. 2. Why is this array flexible in size? Best regards, Krzysztof
