    Subject[PATCH V2 1/3] dt-bindings: thermal: qcom: add PMIC5 Gen2 ADC_TM bindings
    Date
    Add documentation for PMIC5 Gen2 ADC_TM peripheral.
    It is used for monitoring ADC channel thresholds for PMIC7-type
    PMICs. It is present on PMK8350, like PMIC7 ADC and can be used
    to monitor up to 8 ADC channels, from any of the PMIC7 PMICs
    on a target, through PBS(Programmable Boot Sequence).
