Sure,
I will drop these and will just add the REF to mmc-slot

  patternProperties:
    "^slot@[0-9]+$":
-    type: object
-    description: A slot node representing an MMC, SD, or SDIO slot.
-
-    allOf:
-      - $ref: mmc-controller.yaml
-
-    properties:
-      reg:
-        description: Slot ID.
-        minimum: 0
+    $ref: mmc-slot.yaml

How to do that?

dt_binding_check complains that mmc@f0008000: slot@0: 'compatible' is a 
required property.

If the mmc-slot yaml is a generic binding then shall we move the 
compatible to its specific binding(amlogic,meson-mx-sdio.yaml)?

or you could just add it in your .dts files.

Won't it be redundant to have it?
