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?
