   4 Subject: [PATCH] arm64: dts: qcom: ipq8074: add critical thermal trips
   5
   6 According to bindings, thermal zones must have associated trips as well.
   7 Since we currently dont have CPUFreq support and thus no passive cooling
   8 lets start by defining critical trips to protect the devices against
   9 severe overheating.
