I'm fine with this method (In fact it was the first thing that I tried, I added a .set_rate method to ref_clk, it worked well for me). However I wonder whether first initializing the clock with the wrong value (24 MHz) and later correcting it via clk_set_rate() would break something. In the meantime, the data in the clock tree do not reflect the actual frequencies that are present on the SoC.
