I have trouble understanding this part:

> Beware, messing out with your clocks via sysfs without knowing what you are doing may permanently damage your device at the hardware level, so if you're clueless, don't mess around.

Anyway, very nice and informative article, thanks !

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
