Actually four patches...

I don't find this change explained in commit msg. What is more, it looks
incorrect. All properties and patternProperties should be explained in
top-level part.

Defining such properties (with big piece of YAML) in each if:then: is no
readable.
I can't figure out another way. I need to require certain properties for
a compatible string AND certain enum/const for certain properties which
are inside patternProperties for "^(ethernet-)?port@[0-9]+$" by reading
the compatible string.
requiring properties is not equal to defining them and nothing stops you
from defining all properties top-level and requiring them in
allOf:if:then:patternProperties.

If I put allOf:if:then under patternProperties, I can't do the latter.
You can.
Am I supposed to do something like this:

patternProperties:
   "^(ethernet-)?ports$":
     type: object

     patternProperties:
       "^(ethernet-)?port@[0-9]+$":
         type: object
         description: Ethernet switch ports

         unevaluatedProperties: false

         properties:
           reg:
             description:
               Port address described must be 5 or 6 for CPU port and
               from 0 to 5 for user ports.

         allOf:
           - $ref: dsa-port.yaml#
           - if:
               properties:
                 label:
                   items:
                     - const: cpu
             then:
               allOf:
                 - if:
                     properties:
Not really, this is absolutely unreadable.

Usually the way it is handled is:

patternProperties:
   "^(ethernet-)?ports$":
     type: object

     patternProperties:
       "^(ethernet-)?port@[0-9]+$":
         type: object
         description: Ethernet switch ports
         unevaluatedProperties: false
         ... regular stuff follows

allOf:
 - if:
     properties:
       compatible:
         .....
   then:
     patternProperties:
       "^(ethernet-)?ports$":
         patternProperties:
           "^(ethernet-)?port@[0-9]+$":
             properties:
               reg:
                 const: 5


I admit that it is still difficult to parse, which could justify
splitting to separate schema. Anyway the point of my comment was to
define all properties in top level, not in allOf.

allOf should be used to constrain these properties.

Best regards,
Krzysztof
