Subject: [PATCH] ARM: dts: qcom: pm8941: Add vadc nodes needed to estimate an ocv
Date: Fri, 30 Mar 2018 21:04:08 +0100 [thread overview]
Message-ID: <20180330200408.12608-1-ctatlor97@gmail.com> (raw)
vbat_sns is needed to estimate a fairly accurate on chip voltage
and bat_therm is needed to produce an accurate percentage
from the estimated ocv.
