Subject: [PATCH net-next 15/16] dt-bindings: net: dwmac: Simplify MTL queue props dependencies
Currently the Tx/Rx queues properties interdependencies are described by
means of the pattern: "if: required: X, then: properties: Y: false, Z:
false, etc". Due to very unfortunate MTL Tx/Rx queue DT-node design the
resultant sub-nodes schemas look very bulky and thus hard to read. The
situation can be improved by using the "allOf:/oneOf: required: X,
required: Y, etc" pattern instead thus getting shorter and a bit easier to
comprehend constructions.
Signed-off-by: Serge Semin <Sergey.Semin@...kalelectronics.ru>

Note the solution can be shortened out a bit further by replacing the
single-entry allOf statements with just the "not: required: etc" pattern.
But in order to do that the DT-schema validation tool must be fixed like
this:

Thus all the patterns like
allOf:

required:
- X
could be replaced with just
not:
required:
- X
