From 507b1b28129974691b95d623f78d0604fbaeea09 Mon Sep 17 00:00:00 2001 From: Michael Kao Date: Fri, 4 Jun 2021 17:37:55 +0800 Subject: [PATCH] arm64: dts: mt8183-kukui: Add tboard thermal zones Add tboard thermal zones. The tboard thermal sensors are a kind of NTC sensors which are located on PCB board to correlate the temperature of the case (Tskin). pull-up voltage: 1800 mv pull-up resistor: 75K Vsense = pull-up voltage * Rntc / ( pull-up resistor + Rntc ) AuxIn = Vsense * 4096 / 1500 Signed-off-by: Michael Kao Signed-off-by: Ben Tseng Tested-by: Hsin-Yi Wang Link: https://lore.kernel.org/r/20210604093755.13288-1-ben.tseng@mediatek.com Signed-off-by: Matthias Brugger --- arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi | 14 ++++++++++++++ arch/arm64/boot/dts/mediatek/mt8183.dtsi | 2 +- 2 files changed, 15 insertions(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi b/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi index 1512605..ebcab91 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi @@ -851,6 +851,20 @@ status = "okay"; }; +&thermal_zones { + tboard1 { + polling-delay = <1000>; /* milliseconds */ + polling-delay-passive = <0>; /* milliseconds */ + thermal-sensors = <&tboard_thermistor1>; + }; + + tboard2 { + polling-delay = <1000>; /* milliseconds */ + polling-delay-passive = <0>; /* milliseconds */ + thermal-sensors = <&tboard_thermistor2>; + }; +}; + &u3phy { status = "okay"; }; diff --git a/arch/arm64/boot/dts/mediatek/mt8183.dtsi b/arch/arm64/boot/dts/mediatek/mt8183.dtsi index e074c0d..833955d 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt8183.dtsi @@ -673,7 +673,7 @@ nvmem-cell-names = "calibration-data"; }; - thermal-zones { + thermal_zones: thermal-zones { cpu_thermal: cpu_thermal { polling-delay-passive = <100>; polling-delay = <500>; -- 2.7.4
