Subject: [PATCH] arm64: dts: qcom: ipq8074: add thermal nodes
|
|
|
|
IPQ8074 has a tsens v2.3.0 peripheral which monitors
|
|
temperatures around the various subsystems on the
|
|
die.
|
|
|
|
So lets add the tsens and thermal zone nodes, passive
|
|
CPU cooling will come in later patches after CPU frequency
|
|
scaling is supported.
