Hi Ondrej.
My bot found errors running 'make dt_binding_check' on your patch:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/bridge/nwl-dsi.example.dt.yaml: panel@0: '#address-cells', '#size-cells', 'port@0' do not match any of the regexes: 'pinctrl-[0-9]+' /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/bridge/nwl-dsi.example.dt.yaml: panel@0: 'vcc-supply' is a required property /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/bridge/nwl-dsi.example.dt.yaml: panel@0: 'iovcc-supply' is a required property /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/bridge/nwl-dsi.example.dt.yaml: panel@0: 'reset-gpios' is a required property
Paths look bogus ^^^^
It should be .../rocktech,jh057n00900.yaml: ...
The example in nwl-dsi.yaml contains: compatible = "rocktech,jh057n00900";
So the example is checked against your updated binding. And the binding check fails because the example is no longer valid.
Ah, now I understand.
This needs to be fixed as we do not wat to introduce new errors. Either the example or the binding needs the fix.
I think we can unrequire the supplies, but reset is needed really.
The panel only has one port, so there should be no address/size-cells in the example, and port@0 should be just port to match existing binding. If it had multiple ports, port@0 would have to be inside ports { } node anyway, according to the existing binding. Then add reset-gpios to the example...
And that should fix it.
I'll prepare the patch shortly.
