TypeError: unhashable type: 'dict'

With the dt-schema 2023.1 and Python 3.11 (Debian testing) I'm getting the following erorr now:

This was caused by a binding's patch by other developer, which has:

  compatible:
    enum:
      - qcom,sc7180-dp
      - items:
          - enum:
              - qcom,sm8450-dp
              - qcom,sm8550-dp
          - const: qcom,sm8350-dp

So, most likely, this can now be closed unless you want to handle such complex enum entries (I don't even know if this is valid or not).

Did this just start with python 3.11? I've been using it since before it was released.

That's not a valid schema anyways. Looks like a 'oneOf' is needed in there.
