[PATCH 2/2] arm64: dts: ti: k3-am62p-verdin: Adjust temperature trip points

From: João Paulo Gonçalves
Date: Mon Jun 23 2025 - 12:24:00 EST


From: João Paulo Gonçalves <joao.goncalves@xxxxxxxxxxx>

While the TI AM62P supports a junction temperature (Tj) of up to 125°C
for industrial and automotive parts, Toradex Verdin-AM62P hardware
lifetime guarantees consider a 105°C Tj. Change the passive trip points
to 95°C and the critical trip points to 105°C to be compliant with the
hardware specifications.
