Subject: [PATCH v3 1/5] usb: musb: call musb_port_suspend from musb_bus_suspend
Date: Fri, 18 Oct 2013 11:39:31 +0200 [thread overview]
Message-ID: <1382089175-13487-2-git-send-email-zonque@gmail.com> (raw)
In-Reply-To: <1382089175-13487-1-git-send-email-zonque@gmail.com>
Make musb_port_suspend() externally available, and call it when to host
goes into suspend. This allows the core to go into suspend while a
device is connected.
