Subject: [PATCH V3 09/11] power: charger-manager: Not to start charging directly in cable nofitication.
Date: Fri, 19 Dec 2014 17:55:21 +0900	[thread overview]
Message-ID: <1418979323-7188-10-git-send-email-jonghwa3.lee@samsung.com> (raw)
In-Reply-To: <1418979323-7188-1-git-send-email-jonghwa3.lee@samsung.com>

This patch prevents direct charging control in cable notification.
It sets only input current limit according to cable type and yields charging
control to be done by cm_monitor() where charging management proceeds.
It may loose few ms to enable charging compared to before, even though it's
more important that charging is enabled always in safe context.
