The binding looks like a panel-simple-dsi.yaml candidate.
Only differen is enable-gpios versus reset-gpios

Could you check if we can use panel-simple-dsi-yaml.

This is the only difference, the panel only has a reset signal and no
enable signal.

But I can add a reset-gpios to panel-simple-dsi.yaml, would it be ok ?

Yes, that would be fine as long as it is not a required property.
It was a mistake we did not add it from the beginning.

There has been patches floating to add reset-gpios to panle.simple.c
that I rejected - this was also wrong.
Really simple and dumb panels has no reset but dsi panels that
panel-simple supports too has a reset.
