When we have no camera mezzanine attached it is still possible to run the
test-pattern generator of the CSID block.
As an example:
media-ctl --reset
yavta --no-query -w '0x009f0903 1' /dev/v4l-subdev2
yavta --list /dev/v4l-subdev2
media-ctl -d /dev/media0 -V '"msm_csid0":0[fmt:UYVY8_1X16/1920x1080 field:none]'
media-ctl -l '"msm_csid0":1->"msm_ispif0":0[1]'
media-ctl -d /dev/media0 -V '"msm_ispif0":0[fmt:UYVY8_1X16/1920x1080 field:none]'
media-ctl -l '"msm_ispif0":1->"msm_vfe0_rdi0":0[1]'
media-ctl -d /dev/media0 -V '"msm_vfe0_rdi0":0[fmt:UYVY8_1X16/1920x1080]'
media-ctl -d /dev/media0 -p
yavta -B capture-mplane --capture=5 -n 5 -I -f UYVY -s 1920x1080 --file=TPG-UYVU-1920x1080-000-#.bin /dev/video0
