I also looked at the ANX7625 datasheet at the time and it was pretty clear to me that this was not something customers could tune without ANX's help, but it'd be great if Xin Ji can describe a bit more. > > Thanks, > Xin > [snip]

Hi Laurent Pinchart, thanks for the coment, I'll add more detail explain
about the value means.

Hardcoding it in the driver is certainly not a good option, but
hardcoding it in DT isn't either unless you can explain how the value
should be computed. "Contact the vendor" isn't good enough.

Do I have to go dig that up? If it was more than a week ago, assume I
don't remember. This is 1 of 100 bindings a week.
Justify why this is needed in your commit message.

Why do we have the property if we're not supposed to add it.

Wouldn't we have a 'port' node if audio is to be enabled?

Doesn't look like anything from video-interfaces.yaml is used. This

Hi Rob, I get Laurent/Rob comments before, and explained why we needs
these DT properties, so far, I didn't get any response.
Hi Rob Herring and Laurent, for the DT property lane0/1-swing, Google
engineer has strong demond for them, they don't want to move DP swing
adjusting to kernel, thus may cause change the driver code in each
project, so config them in DT is a best option.
Thanks,
