Subject: arm64: dts: ti: k3-am62p-verdin: Adjust temperature trip points
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3b08f8a34a2061d89a2411d04a675b3860d4f9cc;p=users%2Fjedix%2Flinux-maple.git

arm64: dts: ti: k3-am62p-verdin: Adjust temperature trip points

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.
