The thermal zone uses spmi-temp-alarm as sensor. The trip points correspond to stage 1 and 2 temperatures. Stage 2 shutdown is disabled, instead the stage 2 temperature is configured as critical trip point to allow for an ordely shutdown. 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 Signed-off-by: Matthias Kaehlcke <mka@chromium.org> --- 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 | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+)
