Subject: [PATCH 2/2] arm64: dts: qcom: sc8280xp-pmics: Add more temp-alarm devices
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)
}
