Date: Thu, 23 Sep 2021 14:23:11 -0700 From: Bjorn Andersson <bjorn.andersson@...aro.org> To: Andy Gross <agross@...nel.org>, Bjorn Andersson <bjorn.andersson@...aro.org> Cc: Zhang Rui <rui.zhang@...el.com>, Daniel Lezcano <daniel.lezcano@...aro.org>, Amit Kucheria <amitk@...nel.org>, Rob Herring <robh+dt@...nel.org>, Thara Gopinath <thara.gopinath@...aro.org>, Dmitry Baryshkov <dmitry.baryshkov@...aro.org>, linux-arm-msm@...r.kernel.org, linux-pm@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v2 4/4] arm64: dts: qcom: sdm845: mtp: Add vadc channels and thermal zones Downstream defines four ADC channels related to thermal sensors external to the PM8998 and two channels for internal voltage measurements. Add these to the upstream SDM845 MTP, describe the thermal monitor channels and add thermal_zones for these. Signed-off-by: Bjorn Andersson <bjorn.andersson@...aro.org> --- In addition to the iio channels exposed by v1, Daniel wanted thermal_zones... Changes since v1: - Enable the pm8998_adc_tm and describe the ADC channels - Add thermal-zones for the new channels arch/arm64/boot/dts/qcom/sdm845-mtp.dts | 128 ++++++++++++++++++++++++ 1 file changed, 128 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sdm845-mtp.dts b/arch/arm64/boot/dts/qcom/sdm845-mtp.dts index 52dd7a858231..e3b40daef801 100644 --- a/arch/arm64/boot/dts/qcom/sdm845-mtp.dts +++ b/arch/arm64/boot/dts/qcom/sdm845-mtp.dts @@ -10,6 +10,8 @@ #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/regulator/qcom,rpmh-regulator.h> #include "sdm845.dtsi" +#include "pm8998.dtsi" +#include "pmi8998.dtsi" / { model = "Qualcomm Technologies, Inc.
