Subject: [PATCH 1/1] arm64: dts: mt8183-kukui: Enable thermal Tboard
Date: Fri, 9 Apr 2021 15:11:58 +0800	[thread overview]
Message-ID: <20210409071158.2346-1-michael.kao@mediatek.com> (raw)

Add Tboard thermal sensor settings.

pull-up voltage: 1800 mv
pull-up resistor: 75K

Vsense = pull-up voltage * Rntc / ( pull-up resistor + Rntc )
AuxIn = Vsense * 4096 / 1500

TEST=boot kukui
     check /sys/class/thermal/thermal_zone*/type
     check /sys/class/thermal/thermal_zone*/temp
