Hi Angelo,
Yes, MT8188 ETHDR is fully compatible with MT8195, so we didn't add its
compatible name to the driver but just listed it in dt-bindings.
May I double check with you that
I see there is a short description regarding "items" object:
# items is a list of possible values for the property. The number of
# values is determined by the number of elements in the list.
# Order in lists is significant, order in dicts is not
in https://docs.kernel.org/devicetree/bindings/writing-schema.html
So does the compatible has to be:
"mediatek,mt8188-disp-ethdr", "mediatek,mt8195-disp-
ethdr" rather than in reversed order?
However, I couldn't find any description mentions the order in
Documentation/devicetree/bindings/writing-schema.rst
Not sure if the order in "items" object does not matter after then.
No the order doesn't matter in that sense. If you check the other bindings,
you'll see that the rule is to order by name, which your change as well does.
It's fine.
P.S.: In case you didn't know, `make dt_binding_check` and `make dtbs_check`
will validate your bindings and your devicetrees against the bindings.
Regards,
Angelo
Thanks,

Is MT8188's ETHDR fully compatible with MT8195's ETHDR?
If it is, you're not adding a mt8188 specific compatible string in
the driver and
this means that the devicetree will look like:
compatible = "mediatek,mt8195-disp-ethdr", "mediatek,mt8188-disp-
ethdr"
...so the proposed doc change works.
