Hi Rui,
I am trying to get a OV5645 camera to work with a imx7d-pico board on
linux-next 20190628.
Here is the log:
[ 0.285361] videodev: Linux video capture interface: v2.00
[ 3.684025] csi: Registered csi capture as /dev/video0
..
[ 3.689618] imx-media: subdev csi bound
[ 4.055676] imx-media: imx7-mipi-csis.0:1 -> csi-mux:1
[ 4.061032] imx-media: csi-mux:2 -> csi:0
[ 4.065339] imx-media: ov5645 3-003c:0 -> imx7-mipi-csis.0:0
I try to follow the instructions from
Documentation/media/v4l-drivers/imx7.rst to setup the links, which
would be the following for imx7d-pico:
media-ctl -l "'ov5645 3-003c':0 -> 'imx7-mipi-csis.0':0[1]"
media-ctl -l "'imx7-mipi-csis.0':1 -> 'csi_mux':1[1]"
media-ctl -l "'csi_mux':2 -> 'csi':0[1]"
media-ctl -l "'csi':1 -> 'csi capture':0[1]"
The first command succeeds, but the second one fails:
# media-ctl -l "'imx7-mipi-csis.0':1 -> 'csi_mux':1[1]"
Unable to parse link: Invalid argument (22)
Any ideas, please?
Thanks,
Fabio Estevam

I have also tested it on a imx7s-warp and I got the same error.
Please let me know if you have any ideas on how to solve this problem.
Thanks

What does media-ctp -p say?

Thanks for this hint!
I managed to fix the media-ctl failure by looking at media-ctl -p output.
Documentation/media/v4l-drivers/imx7.rst mentions "csi_mux", but
media-ctl says "csi-mux", so I needed to change it to:
media-ctl -l "'imx7-mipi-csis.0':1 -> 'csi-mux':1[1]"
and then I see no errors after the media-ctl command.
I will send a patch fixing Documentation/media/v4l-drivers/imx7.rst .
Thanks,
Fabio Estevam
