[PATCH 0/3] arm64: dts: qcom: ipq6018: support thermal sensors

[Mantas Pucka]

IPQ6018 have a thermal sensor HW that's compatible with existing
qcom-tsens driver, so add dt-binding and enable it in devicei-tree.

Mantas Pucka (3):
  dt-bindings: thermal: qcom-tsens: add IPQ6018 compatible
  arm64: dts: qcom: ipq6018: add tsens node
  arm64: dts: qcom: ipq6018: add thermal zones

[PATCH 3/3] arm64: dts: qcom: ipq6018: add thermal zones

[Mantas Pucka]

Add thermal zones to make use of thermal sensors data. For CPU zone,
add cooling device that uses CPU frequency scaling.
