Subject: [PATCH 2/2] arm64: dts: qcom: sc8280xp-pmics: Add more temp-alarm devices
Date: Sat, 11 Jan 2025 16:32:08 +0800	[thread overview]
Message-ID: <20250111083209.262269-2-mitltlatltl@gmail.com> (raw)
In-Reply-To: <20250111083209.262269-1-mitltlatltl@gmail.com>

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)
    }
