Subject: [PATCH v5 08/12] power: supply: smb347-charger: Utilize generic regmap caching
Date: Sat, 17 Jul 2021 21:21:30 +0300 [thread overview]
Message-ID: <20210717182134.30262-9-digetx@gmail.com> (raw)
In-Reply-To: <20210717182134.30262-1-digetx@gmail.com>
Utilize generic regmap caching in order to avoid unnecessary slow I2C
accesses each time the supply status updated and remove local caching
of charger state to make code cleaner.
