Re: [PATCH v2 3/3] dt-bindings: display: convert panel-dpi to DT schema

Hi Rob.

...

+properties:

• compatible:
• contains:

•  const: panel-dpi
  

• description:

•  Shall contain "panel-dpi" in addition to an optional panel-specific
  

•  compatible string defined in individual panel bindings.
  

•  "panel-dpi" can be used alone, thus no dedicated binding file
  

•  is required for each and every panel.
  

While this has occurred, I don't think the schema should allow it. I think a 'minItems: 2' should be added here.

AFAIK, MIPI DPI just defines a spec for what already existed. Maybe it constrains things somewhat, but to the extent why we require a panel specific compatible in the first place? Doubtful...

You triggered me to re-read some old thread about this. And I think I got it now.

Based on a proposal you made some weeks ago I did it like this: properties: compatible: description: Shall contain a panel specific compatible and "panel-dpi" in that order. items: - {} - const: panel-dpi

So no constraints on the panel specific compatible, expect that it is present. And panel-dpi must be listed as the second compatible.

Updated the example too. Will post a v3.

Thanks!
