Subject: [PATCH v4 4/4] power: supply: max17040: Send uevent in SOC and status change
Date: Thu, 31 Oct 2019 15:41:34 -0300	[thread overview]
Message-ID: <20191031184134.30621-5-matheus@castello.eng.br> (raw)
In-Reply-To: <20191031184134.30621-1-matheus@castello.eng.br>

Notify core through power_supply_changed() in case of changes in state
of charge and power supply status. This is useful for user-space to
efficiently update current battery level.
