Subject: [PATCH v3] arm64: dts: qcom: pmi8998: add rradc node
Date: Mon, 17 Oct 2022 20:09:02 +0100 [thread overview]
Message-ID: <20221017190902.2282899-1-caleb.connolly@linaro.org> (raw)
Add a DT node for the Round Robin ADC found in the PMI8998 PMIC.
The RRADC reports PMIC die and skin temperatures, as well as
battery/charger thermals. It also reports USB and DC charger voltage and
current measurements.
