There are 4 Qualcomm PMIC Die Temp Alarm Sensor Devices under windows os, in separate dt files, pm8350c and pmr735a have already support temp alarm, add the rest 2 devices for sc8280xp-pmic. Temperature trip points are from dsdt(Temp. in tenths of degrees Kelvin). example: Name (TPSV, 0x0E60) // 0x0E60 - 2730 = 950 Method (_PSV, 0, NotSerialized) // _PSV: Passive Temperature { Return (\_SB.TZ15.TPSV) } Name (TCRT, 0x0F28) // 0X0F28 - 2730 = 1150 Method (_CRT, 0, NotSerialized) // _CRT: Critical Temperature { Return (\_SB.TZ15.TCRT) } Signed-off-by: Pengyu Luo <mitltlatltl@gmail.com> --- arch/arm64/boot/dts/qcom/sc8280xp-pmics.dtsi | 56 ++++++++++++++++++++ 1 file changed, 56 insertions(+)
