[Armbian build PR] - rk3399: adjust opi4lts thermal trip points


Recommended Posts

Description

One user on the forum (see https://forum.armbian.com/topic/27798-orange-pi-4-lts-default-thermal-trip-point-issues/) found issues with Orange PI 4 LTS thermal trip points.

Looking into the problem, it is related to a patch introduced long time ago that changed the thermal trip points away from the vendor (and mainline kernel too) supplied ones.

After some stress testing with openssl and mbw combined, my board froze and I had to shutdown it manually, let it cool and restart to have again a working system. It happens that, at least on my and forum user cases, the trip points are not doing what they expect to do.

This patch corrects the trip points for Opi4 LTS: after repeating the same stress test, the kernel is capable of keeping the temperature under control without freezes

Jira reference number AR-1812

  • [x] Tested device tree with trip points on live system
