In this case dt_binding_check doesn't recognize input-debounce. The following seems to
work for the provided example:

-    $ref: /schemas/pinctrl/pinmux-node.yaml#
+    allOf:
+      - $ref: /schemas/pinctrl/pincfg-node.yaml#
+      - $ref: /schemas/pinctrl/pinmux-node.yaml#
+
+    additionalProperties: false
 

with this included in the led node properties:
+      input-debounce: true

If I understand correctly, "unevaluatedProperties: false" (like for the leds binding)
would allow everything from the referenced pincfg-node and pinmux-node schemas, which is
more than is actually supported by this device.
