Subject: [PATCH 13/40] ab8500_charger: Prevent auto drop of VBUS
Date: Fri, 15 Feb 2013 12:44:43 +0000 [thread overview]
Message-ID: <1360932310-30065-14-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1360932310-30065-1-git-send-email-lee.jones@linaro.org>
Do not set higher current in stepping functionality if VBUS is dropping.
After VBUS has dropped try to set current once again. If dropping again
then we have found the maximum capability of the charger.
