Marco Felsch - April 5, 2019, 6:03 a.m.
Currently every driver needs to parse the connector endpoints by it self.
This is the initial work to make this generic. The generic connector has
some common fields and some connector specific parts. The generic one
includes:
  - type
  - label
  - remote_port (the port where the connector is connected to)
  - remote_id   (the endpoint where the connector is connected to)

The specific fields are within a union, since only one of them can be
available at the time. Since this is the initial support the patch adds
only the analog-connector specific ones.

Break the line please

I liked best the description in the commmit message:
@remote_port: identifier of the remote endpoint port the connector connects to

but I see the exact same sentence you used already in an existing
comment, so feel free to chose the one you prefer.

identifier of the remote endpoint the connector connect/belong to?

just "connector configuration" ?

All minor stuff, feel free to pick what you like from the comments.

Let me change this. I was inspired by the v4l2_fwnode_link description.
I think the commit description is a bit intuitiver.

Here too.

Yes that sounds better.

The connector and connetor.analog description is inspired by the
v4l2_fwnode_endpoint description. Your sounds a bit more natural so I
will pick them.

Okay, I will drop both commit messages.

Thanks a lot for the review =) I will add your Reviewed-by tag in the

I would drop VGA and DVI for now. Only add them if they are needed. These
connectors are rarely seen these days.

connetor -> connector
