Subject: [PATCH v3 03/10] power: supply: Support battery temperature device-tree properties
Date: Fri, 14 Aug 2020 00:34:02 +0300	[thread overview]
Message-ID: <20200813213409.24222-4-digetx@gmail.com> (raw)
In-Reply-To: <20200813213409.24222-1-digetx@gmail.com>

The generic battery temperature properties are already supported by the
power-supply core. Let's support parsing of the common battery temperature
properties from a device-tree.
