[v4,11/12] arm64: dts: qcom: sc8280xp-x13s: Add PM8280_{1/2} ADC_TM5 channels
Commit Message
Add ADC_TM5 channels of PM8280_{1/2} for monitoring the temperature from
external thermistors connected to AMUX pins. The temperature measurements
are collected from the PMK8280's VADC channels that expose the
measurements from secondary PMICs PM8280_{1/2}.

Please try to keep the nodes sorted alphabetically (e.g. this one should
go before &pmk8280_pon_pwrkey).

Thanks for spotting that, I fixed up the order.
