Hi Rob,

Running:
1- make dt_binding_check | grep access-control
2- make dt_binding_check 
DT_SCHEMA_FILES=Documentation/devicetree/bindings/access-controllers/access-controller.yaml
from Krzysztof's slideset

with

pip3 show dtschema
Name: dtschema
Version: 2023.9

and

pip3 show yamllint
Name: yamllint
Version: 1.32.0

I don't see any of the errors reported by the robot. I have to clone
your repository to reproduce it.

Should I resubmit with a clean dt-check using the latest dtschema?

***********
However, I get:
warning: ignoring duplicate '$id' value 
'http://devicetree.org/schemas/reserved-memory/framebuffer.yaml#
warning: ignoring duplicate '$id' value 
'http://devicetree.org/schemas/reserved-memory/memory-region.yaml#
warning: ignoring duplicate '$id' value 
'http://devicetree.org/schemas/reserved-memory/shared-dma-pool.yaml#
warning: ignoring duplicate '$id' value 
'http://devicetree.org/schemas/reserved-memory/reserved-memory.yaml

Above warnings disappears when switching to:
pip3 show dtschema
Name: dtschema
Version: 2023.7

The above YAMLs seem to be duplicated in dtschema's latest version.
I guess it's a synchro that needs to be done since:
