From: Raphael Poggi <[email protected]> clock_propagate() has an assert that clk->source is NULL, i.e. that you are calling it on a clock which has no source clock. This made sense in the original design where the only way for a clock's frequency to change if it had a source clock was when that source clock changed. However, we subsequently added multiplier/divider support, but didn't look at what that meant for propagation.
If a clock-management device changes the multiplier or divider value on a clock, it needs to propagate that change down to child clocks, even if the clock has a source clock set. So the assertion is now incorrect. Remove the assertion.
