Subject: [PATCH 3/6] usb: s3c-hsotg: do not disconnect gadget when receiving ErlySusp intr
Date: Thu, 12 Sep 2013 16:18:49 +0200 [thread overview]
Message-ID: <1378995532-32142-4-git-send-email-r.baldyga@samsung.com> (raw)
In-Reply-To: <1378995532-32142-1-git-send-email-r.baldyga@samsung.com>
From: Chanho Park <chanho61.park@samsung.com>
DWC2 databook indicates if the core sets "ErlySusp" bit, an idle state has been
detected on the USB for 3 ms. This situation can be occurred when waiting
a request from user daemon. So, we should keep the connection between udc and
gadget even though this interrupt is occurred.
