Subject: [PATCH v2] arm64: dts: qcom: sc7180-trogdor: Delete ADC config for unused thermistors
Date: Fri,  3 Sep 2021 12:22:19 -0700	[thread overview]
Message-ID: <20210903122212.v2.1.I9777d0036ecbb749a4fb9ebb892f94c6e3a51772@changeid> (raw)

The charger thermistor on Lazor, CoachZ rev1 and Pompom rev1+2 is
either the wrong part or not stuffed at all, the same is true for
the skin temperature thermistor on CoachZ rev1. The corresponding
thermal zones are already disabled for these devices, in addition
delete the ADC nodes of the thermistors.

For Lazor and CoachZ rev1 also disable the PM6150 ADC and thermal
monitor since none of the ADC channels is used.

Signed-off-by: Matthias Kaehlcke <mka@chromium.org>

Changes in v2:
- also disable the ADC for Lazor and CoachZ rev1
- updated commit message
