Subject: [PATCH 1/1] arm64: dts: mt8183-kukui: Update Tboard sensor mapping table
Date:   Wed, 3 Nov 2021 11:30:44 +0800
Message-ID: <20211103033044.2777-1-ben.tseng@mediatek.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

According to auxadc change the readback value from raw data to Vsense.
Update the tboard table that temperature map to Vsense.

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

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