Subject: [PATCH 4/4] arm64: dts: qcom: sc7180: Disable charger thermal zone for coachz rev1 and rev2
Date: Thu, 4 Mar 2021 10:04:15 -0800 [thread overview]
Message-ID: <20210304100341.4.I95b8a63103b77cab6a7cf9c150f0541db57fda98@changeid> (raw)
In-Reply-To: <20210304180415.1531430-1-mka@chromium.org>
CoachZ rev1 and rev2 are stuffed with a 47k NTC as thermistor for the
charger temperature which currently isn't supported by the PM6150 ADC
driver. Disable the charger thermal zone to avoid the use of bogus
temperature values.
