Subject[PATCH] arm64: qcom: sc7180: trogdor: Add ADC nodes and thermal zone for charger thermistor
Date
From: Antony Wang <antony_wang@compal.corp-partner.google.com>

Trogdor has a thermistor to monitor the temperature of the charger IC.
Add the ADC (monitor) nodes and a thermal zone for this thermistor.
