This patch adds uvc_function_suspend and uvc_function_resume for uvc function. With this patch, if usb bus enter suspend or resume state, the usb controller driver will call the uvc_function_suspend or uvc_function_resume to send event to uvc app. Change-Id: I9c584aae25298747c5a287243cb3efd71c8adfe6 Signed-off-by: William Wu <william.wu@rock-chips.com> Signed-off-by: Frank Wang <frank.wang@rock-chips.com>
