Subject: [PATCH v3 04/11] usb: dwc3-omap: Remove explicit writes to SYSCONFIG register
Date: Fri, 25 Jan 2013 08:30:48 +0530 [thread overview]
Message-ID: <1359082855-7404-5-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1359082855-7404-1-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.
