Hi Dinh, I'd prefer not to add the DT property, at least for now. I doubt if anyone will want to enable it. Besides, I'm not sure that a property which only enables a driver feature is appropriate for DT. So, if you redo patch 1 to remove the DT property read, and drop patch 2, you can add my acked-by. Thanks. -- Paul -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
