I know how to change mode. kernel driver is no bug, and you need’t to recompliling kernel or decompiling dtb. you can use cmd like this to change mode:

media-ctl -d /dev/media0 --set-v4l2 ‘“ov5647 5-0036”:0[fmt:SGBRG10_1X10/2592x1944]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:0[fmt:SGBRG10_1X10/2592x1944]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:0[crop:(0,0)/2592x1944]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:2[crop:(0,0)/2592x1944]’
v4l2-ctl -d /dev/video0 --set-selection=target=crop,top=0,left=0,width=2592,height=1944

media-ctl -d /dev/media0 --set-v4l2 ‘“ov5647 5-0036”:0[fmt:SGBRG10_1X10/1920x1080]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:0[fmt:SGBRG10_1X10/1920x1080]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:0[crop:(0,0)/1920x1080]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:2[crop:(0,0)/1920x1080]’
v4l2-ctl -d /dev/video0 --set-selection=target=crop,top=0,left=0,width=1920,height=1080

media-ctl -d /dev/media0 --set-v4l2 ‘“ov5647 5-0036”:0[fmt:SGBRG10_1X10/640x480]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:0[fmt:SGBRG10_1X10/640x480]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:0[crop:(0,0)/640x480]’
media-ctl -d /dev/media0 --set-v4l2 ‘“rkisp-isp-subdev”:2[crop:(0,0)/640x480]’
v4l2-ctl -d /dev/video0 --set-selection=target=crop,top=0,left=0,width=640,height=480
