Subject: [PATCH v3 4/6] dt-bindings: power: supply: max17040: Add maxim,rcomp
Date: Wed, 24 Jun 2020 18:56:31 +0300 [thread overview]
Message-ID: <20200624155633.3557401-5-iskren.chernev@gmail.com> (raw)
In-Reply-To: <20200624155633.3557401-1-iskren.chernev@gmail.com>
To compensate for the battery chemistry and operating conditions the
chips support a compensation value. Specify one or two byte compensation
via the maxim,rcomp byte array.
