sunxi-h3-h5.dtsi   csi_pins:csi-pins 内添加 “PE1”

			csi_pins: csi-pins {

运行测试

配置好设备树，重启后，

root@orangepilite:~# v4l2-ctl --list-devices
sun6i-csi (platform:camera):
        /dev/video0

cedrus (platform:cedrus):
        /dev/video2
        /dev/media0

Allwinner Video Capture Device (platform:sun6i-csi):
        /dev/media1

sun8i-di (platform:sun8i-di):
        /dev/video1

使用fswebcam 保持图片

fswebcam -d /dev/video0 -r 640x480 --fps 30 -p UYVY -S 30 1.jpg

修改输出的格式为 1920×1080

media-ctl --device /dev/media1 --set-v4l2 '"ov5640 1-003c":0[fmt:UYVY/1920x1080]'
fswebcam -d /dev/video1 -r 1920x1080 -D 3 --jpeg 100 1.jpg
