From 8f053e5616352943e16966f195f5a7a161e6fe7d Mon Sep 17 00:00:00 2001
From: Mantas Pucka <mantas@8devices.com>
Date: Thu, 25 Jan 2024 11:04:12 +0200
Subject: [PATCH] arm64: dts: qcom: ipq6018: add thermal zones
Add thermal zones to make use of thermal sensors data. For CPU zone,
add cooling device that uses CPU frequency scaling.
