From 56d3067cb694ba60d654e7f5ef231b6fabc4697f Mon Sep 17 00:00:00 2001

Subject: [PATCH] arm64: dts: qcom: ipq8074: add critical thermal trips
According to bindings, thermal zones must have associated trips as well.
Since we currently dont have CPUFreq support and thus no passive cooling
lets start by defining critical trips to protect the devices against
severe overheating.
