The Asia Better Technology (ABT) Y030XX067A panel is a 3.0" 320x480
24-bit IPS LCD panel. Its particularity is that it has non-square pixels
(as it is 4:3 for a resolution of 320x480), and that it requires odd
lines to be sent as RGB and even lines to be sent as GRB on its 8-bit
bus.

The binding is missing:
required:
  - compatible
  - reg
  - power-supply
  - reset-gpios
  - ...

additionalProperties: false

So r-b only with these added.

Stupid mistake, sorry about that.

I don't have any V2 in my inbox, but looks like it is in linux-next now:

/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/display/panel/abt,y030xx067a.example.dt.yaml:
panel@0: 'spi-max-frequency' does not match any of the regexes:
'pinctrl-[0-9]+'

Yes, Sam told me on IRC I could fix it while applying and avoid the V2.

"make dt_binding_check

Even if you do 'touch
Documentation/devicetree/bindings/display/panel/abt,y030xx067a.yaml'
or do a clean build?

I can't think of any kernel or dt-schema changes which would explain
the difference. This is purely related to 'additionalProperties:
false'.

Ok, I see it now.
Should I use 'unevaluatedProperties: false' instead?

Yes, the issue here is that you add a number of spi properties to the
binding. And you cannot or at least shall not, list them all in this
binding.
So when evaluating the binding the spi-max-frequency should be allowed,
and when a full DT file is checked the tools will catch it there is a
binding that is not known - as you tell it with "unevaluatedProperties:
false" that all prperties must be known.
