This property needs to be documented. In my opinion it should also be a
property of the endpoint sub-node rather than the toplevel device
node since
this is a configuration of the endpoint format.
Agreed, it's really a config of the backend capture endpoint. I'll
move it
there and also document it in
Documentation/devicetree/bindings/media/i2c/adv7180.txt.
er, scratch that. ITU-R BT.656 compatibility is really a property of the
bt.656 bus. It
should be added to v4l2 endpoints and parsed by
v4l2_of_parse_endpoint(). I've created
a patch to add a "bt656-mode" property to v4l2 endpoints and will copy
all the maintainers.
