From 7bfd90f5a57e49c3b97929ce1f7868629e3e13d0 Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Thu, 27 Sep 2018 14:22:53 -0700 Subject: [PATCH] arm64: dts: qcom: pm8998: Use ADC temperature to temp-alarm node The temperature information from the temp-alarm block itself is very coarse ("temperature is above/below trip points"). Provide the driver with the die temperature channel of the ADC on the PMIC for more precise readings.
