Subject: [PATCH] arm64: dts: qcs6490-rb3gen2: Add vadc and adc-tm channels
Add support for vadc and adc-tm channels which are used for
monitoring thermistors present on the platform.
- Add the necessary includes for qcom,spmi-adc7-pm7325 and
qcom,spmi-adc7-pmk8350.
- Add thermal zones for quiet-thermal, sdm-skin-thermal, and
xo-thermal, and define their polling delays and thermal sensors.
- Configure the pm7325_temp_alarm node to use the pmk8350_vadc
channel for thermal monitoring.
- Configure the pmk8350_adc_tm node to enable its thermal sensors
and define their registers and settings.
- Configure the pmk8350_vadc node to define its channels and settings
