Subject: [PATCH 0/3] Thermal zones for pm8226, pm8841 and pm8941

Add thermal sensor for pm8226, which is using on chip VADC channel to
report PMIC die temperature. Add thermal zone configurations for
PMIC thermal sensors found in pm8226, pm8841 and pm8941.

Subject: [PATCH 2/3] ARM: dts: qcom: pm8841: Add thermal zone config

Add thermal zone for the PMIC thermal sensor. Temperatures are based on
downstream values, except for critical trip point where 140°C is used
instead of 145°C due to limitations without a configured ADC.
