Subject: [PATCH v1 8/8] usb: otg: palmas-usb: fix cold plug issue
Date: Fri, 25 Jan 2013 08:42:31 +0530 [thread overview]
Message-ID: <1359083551-8524-9-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1359083551-8524-1-git-send-email-kishon@ti.com>
if the cable is connected even before the palmas-usb is loaded, the
cable connect detection event will be missed. It's fixed here by checking
for VBUS line states when palmas-usb is loaded.
