I've tested this series on my Nitrogen6x + BD_HDMI_MIPI daughter board
and have a few questions.

First, why is the tc358743 node in a separate dtsi file? Is this in
order to avoid a failed probe during bootup if the daughter board is
not present? Is this what should be done for every capture device that
targets this platform (like the OV5640 or OV5642)?

Can you provide some details on your testing procedure? In my case I've
reached a point where I get the same 'media-ctl --print-dot' output as
the one from your cover letter but I can't seem to set the EDID nor to
have a gstreamer pipeline (to fakesink). All the EDID v4l2-ctl commands
return "Inappropriate ioctl for device".

Do not hesitate to CC me to Boundary Devices related patches so I can
test them and give some feedback.

Regards,
Gary
