Hello,
I would like to ask some questions about forward porting of the USB
Driver Controller (UDC) from 2.6.34.10 to 3.2.11 kernel.
I see that there are some changes in the gadget framework, and this
is what I have noticed so far:
[1] Functions usb_gadget_register_driver() and
usb_gadget_unregister_driver() are moved up to gadget
driver framework;
[2] usb_gadget_probe_driver() replaced
usb_gadget_register_driver();
[3] There also two new functions added in UDC framework:
xxxxx_start() and xxxx_stop(), example taken from
net2280.c:
static int net2280_start(struct usb_gadget *_gadget,
struct usb_gadget_driver *driver);
static int net2280_stop(struct usb_gadget *_gadget,
struct usb_gadget_driver *driver);
static const struct usb_gadget_ops net2280_ops = {
.get_frame = net2280_get_frame,
.wakeup = net2280_wakeup,
.set_selfpowered = net2280_set_selfpowered,
.pullup = net2280_pullup,
.udc_start = net2280_start,
.udc_stop = net2280_stop,
}
Does anybody have set of guidelines/can point set of guidelines how
to adapt to the new interfaces, if there is forward porting effort to be
made?
Or maybe ad-hoc short description how to do forward porting?
Thank you,
Zoran
