imx8 rtcwakeup VIDIOC_STREAMOFF

happy_892d03

Hardware name: Freescale i.MX8QM MEK (DT) 设备
v4l2 采集yuyv摄像头数据
/unit_tests/SRTC/rtcwakeup.out -d rtc0 -m mem -s 2  休眠，唤醒后，重新显示摄像头数据

求助1、不做VIDIOC_STREAMOFF，rtcwakeup休眠不了，而且会导致视频泛白；
求助2、rtcwakeup休眠前调用VIDIOC_STREAMOFF，但重复多次：视频显示--VIDIOC_STREAMOFF->rtcwakeup-> 视频显示；会出现异常

你那边用的是ov5640和官方驱动吗？如果是，能否提供测试过程和文件，我这边会复现一下
