This thermal sensor can measure temperature from -40000 to 125000, but over 117000 can be critical on this chip. Thus, default critical temperature is now set as 115000 (this driver is using 5000 steps) (Current critical temperature is using it as 90000, but there is no big reason about it) And it doesn't check thermal zone periodically (same as current behavior). You can exchange it by modifying polling-delay[-passive] property. You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS, but you need to take care to use it, since it will call orderly_poweroff() it it reaches to the value. echo $temp > /sys/class/thermal/thermal_zone0/trip_point_0_temp Signed-off-by: Kuninori Morimoto --- v4 -> v5 - no change arch/arm/boot/dts/r8a7791.dtsi | 26 ++++++++++++++++++++++++-- 1 file changed, 24 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/r8a7791.dtsi b/arch/arm/boot/dts/r8a7791.dtsi index 3776974..9b37c80 100644 --- a/arch/arm/boot/dts/r8a7791.dtsi +++ b/arch/arm/boot/dts/r8a7791.dtsi @@ -69,6 +69,25 @@ }; }; + thermal-zones { + cpu_thermal: cpu-thermal { + polling-delay-passive = <0>; + polling-delay = <0>; + + thermal-sensors = <&thermal>; + + trips { + cpu-crit { + temperature = <115000>; + hysteresis = <0>; + type = "critical"; + }; + }; + cooling-maps { + }; + }; + }; + gic: interrupt-controller@f1001000 { compatible = "arm,gic-400"; #interrupt-cells = <3>; @@ -185,12 +204,15 @@ power-domains = <&cpg_clocks>; }; - thermal@e61f0000 { - compatible = "renesas,thermal-r8a7791", "renesas,rcar-thermal"; + thermal: thermal@e61f0000 { + compatible = "renesas,thermal-r8a7791", + "renesas,rcar-gen2-thermal", + "renesas,rcar-thermal"; reg = <0 0xe61f0000 0 0x14>, <0 0xe61f0100 0 0x38>; interrupts = <0 69 IRQ_TYPE_LEVEL_HIGH>; clocks = <&mstp5_clks R8A7791_CLK_THERMAL>; power-domains = <&cpg_clocks>; + #thermal-sensor-cells = <0>; }; timer {
