Subject: [PATCHv1 03/19] power: supply: core: add manufacture date properties
Date: Wed, 13 May 2020 20:55:59 +0200 [thread overview]
Message-ID: <20200513185615.508236-4-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20200513185615.508236-1-sebastian.reichel@collabora.com>
Some smart batteries store their manufacture date, which is
useful to identify the battery and/or to know about the cell
quality.
