This warning is not a new one.

The i2s2 node in stm32mp15xx-dkx.dtsi would require the following binding:
port:
$ref: audio-graph-port.yaml#
unevaluatedProperties: false

However the spi binding requires to introduce a unit address:
patternProperties:
'^port@[0-9]':
$ref: audio-graph-port.yaml#
unevaluatedProperties: false

The warning can be removed by re-ordering the bindings patches in the
serie, as "additionalProperties: true" makes the check more tolerant on
extra properties.
The patch "ASoC: dt-bindings: stm32: i2s: add audio-graph-card port" can
even be merely dropped.
So, I suggest to resend the serie without audio-graph-card patch.

Does it sound too permissive to you ?

Thanks
Olivier
