I guess "fixed" means "fixed at run-time", not "identical rate in all systems"? Since this is the crystal rate, it can vary between boards, but I supposed if "fixed" means "fixed at run-time", considering this as a fixed clock is fine.
But, isn't clk_m also a fixed clock then? I would expect one or two more clocks in this file. What about clk_s, or is that known as clk_32k here?
