Subject: [PATCH v3 4/6] arm64: dts: qcom: sdm845-db845c: enable pmi8998 charger
Date: Fri, 13 May 2022 21:05:10 +0100	[thread overview]
Message-ID: <20220513200512.501156-5-caleb.connolly@linaro.org> (raw)
In-Reply-To: <20220513200512.501156-1-caleb.connolly@linaro.org>

Enable the smb2 charger driver on the db845c and add a simple-battery
node to report the correct VBAT voltage.
