I don't think this works. You now constrain the first dimension which
had only one item before.

Make your example complete and test it.

Hi Krzysztof,

"Official" bindings for MP15: st,syscon = <&syscfg 0x4>;
"Official" bindings for MP13: st,syscon = <&syscfg 0x4 0xff0000>; or
st,syscon = <&syscfg 0x4 0xff000000>;

If I execute make dt_binding_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/net/stm32-dwmac.yaml with:

   For MP15: st,syscon = <&syscfg>;
=>bindings/net/stm32-dwmac.example.dtb: ethernet@40027000: st,syscon:0:
[4294967295] is too short

   For MP15: st,syscon = <&syscfg 0x4 0xff0000>;
=>devicetree/bindings/net/stm32-dwmac.example.dtb: ethernet@40027000:
st,syscon:0: [4294967295, 4, 16711680] is too long

   For MP13: st,syscon = <&syscfg 0x4>; =>
devicetree/bindings/net/stm32-dwmac.example.dtb: ethernet@5800a000:
st,syscon:0: [4294967295, 4] is too short

   For MP13: st,syscon = <&syscfg 0x4 0xff0000 0xff>; =>
devicetree/bindings/net/stm32-dwmac.example.dtb: ethernet@5800a000:
st,syscon:0: [4294967295, 4, 16711680, 255] is too long

So it is seems good :-)

Code is still incorrect, although will work because of how schema parses
matrix. But even by looking it is not symmetrical between allOf:if:then
and properties:. Make it symmetric - apply the number of items on the
second dimension.

It looks correct to me. But it could also be like this:

st,syscon:
items:
- minItems: 3

Either way works. Is that what you are asking for? I'm just happy when
folks can write a working schema.
