Subject: [PATCH v2 3/3] arm64: dts: qcom: sc7180: Add CoachZ rev3
CoachZ rev3 uses a 100k NTC thermistor for the charger temperatures,
instead of the 47k NTC that is stuffed in earlier revisions. Add .dts
files for rev3.
The 47k NTC currently isn't supported by the PM6150 ADC driver.
Disable the charger thermal zone for rev1 and rev2 to avoid the use
of bogus temperature values.
Signed-off-by: Matthias Kaehlcke <mka@...omium.org>

- added CoachZ rev3
