Thanks, it means what it means, it asserts a #define on clk.c whereby root will be able to do very stupid things with clocks...

Ok, but to me it seems to mean that the hardware may be permanently damaged (= a power cycle does not fix the issue) by a wrong clock setting, and I wonder why.

Well the simplest example I can give you is overclocking your CPU or GPU. If you do that past a certain limit, it would be damaging to the hardware don't you agree?
The correct implementation of the power-up script for Rock Pi N10 NPU should be as a kernel module, this way we don't have to enable any dangerous #defines in clk.c

Anyway, very nice and informative article, thanks !
