[PATCH 1/7] arm64: dts: qcom: pm8350: add temp sensor and thermal zone config

[Dmitry Baryshkov]

Add temp-alarm device tree node and a default configuration for the
corresponding thermal zone for this PMIC. Temperatures are based on
downstream values.

[PATCH 4/7] arm64: dts: qcom: pm8350c: stop depending on thermal_zones label

[Dmitry Baryshkov]

Most of SoC device trees do not provide the thermal_zones label. Thus
stop depending on it and use the full path to the thermal zones nodes.
