Sean has already given me a NAK because this function actually return negative values through a ulong return types. I didn’t check into clk-uclass.c and there if get_rate() pointer is not found then it returns a negative value. Since it’s a bit ambiguous I’ve tried to find a different approach but nothing that easy came into my mind. Best regards Giulio Benetti
