The critical trip point at 125°C disables the partial PMIC shutdown at stage 2. Without an IIO input the sensor only reports a limited number of temperatures: - 37°C for temperatures below 105°C - 107°C for temperatures >= 105°C and < 125°C - 127°C for temperatures >= 125°C (the numbers correspond to a stage 1 threshold of 105°C) Signed-off-by: Matthias Kaehlcke Reviewed-by: Douglas Anderson --- Changes in v5: - removed 'stage2-shutdown-disabled' property from spmi-temp-alarm - updated commit message Changes in v4: - updated trip point temperatures to match stage 1 and 2 ones - disabled stage 2 shutdown - updated commit message Changes in v3: - moved 'thermal-zones' node to the beginning of the .dtsi Changes in v2: - defined 'thermal-zones' node in pm8998.dtsi instead of using a label to refer to it - use 105°C hardware trip point as critical trip point - reduced number of trip points to 2 - lowered temperature of passive trip point - updated trip point names and added labels - updated commit message --- arch/arm64/boot/dts/qcom/pm8998.dtsi | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/pm8998.dtsi b/arch/arm64/boot/dts/qcom/pm8998.dtsi index 7eea94701b23..34c259ba3919 100644 --- a/arch/arm64/boot/dts/qcom/pm8998.dtsi +++ b/arch/arm64/boot/dts/qcom/pm8998.dtsi @@ -3,6 +3,31 @@ #include #include +#include + +/ { + thermal-zones { + pm8998 { + polling-delay-passive = <250>; + polling-delay = <1000>; + + thermal-sensors = <&pm8998_temp>; + + trips { + pm8998_alert0: pm8998-alert0 { + temperature = <105000>; + hysteresis = <2000>; + type = "passive"; + }; + pm8998_crit: pm8998-crit { + temperature = <125000>; + hysteresis = <2000>; + type = "critical"; + }; + }; + }; + }; +}; &spmi_bus { pm8998_lsid0: pmic@0 {
