Subject: [PATCH 3/6] usb: dwc3-omap: Remove explicit writes to SYSCONFIG register
Date: Fri, 28 Sep 2012 18:23:12 +0530 [thread overview]
Message-ID: <1348836795-4783-4-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1348836795-4783-1-git-send-email-kishon@ti.com>
The runtime API's takes care of setting the SYSCONFIG register with
appropriate values. Hence explicit writes to SYSCONFIG register is
removed.
