Subject: [PATCH v9 06/14] usb: gadget.h: Add OTG to gadget interface
Date: Wed, 8 Jun 2016 12:03:38 +0300 [thread overview]
Message-ID: <1465376626-30122-7-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1465376626-30122-1-git-send-email-rogerq@ti.com>
The OTG core will use struct otg_gadget_ops to
start/stop the gadget controller.
The main purpose of this interface is to avoid directly
calling usb_gadget_start/stop() from the OTG core as they
wouldn't be defined in the built-in symbol table if
CONFIG_USB_GADGET is m.
