Introducing of the generic access controller bindings for the
access controller provider and consumer devices. Those bindings are
intended to allow a better handling of accesses to resources in a
hardware architecture supporting several compartments.

This patch is based on [1]. It is integrated in this patchset as it
provides a use-case for it.

Diffs with [1]:
- Rename feature-domain* properties to access-control* to narrow
down the scope of the binding
- YAML errors and typos corrected.
- Example updated
- Some rephrasing in the binding description

Changes in V5:
- Diffs with [1]
- Discarded the [IGNORE] tag as the patch is now part of the
patchset

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/access-controllers/access-controller.yaml: access-control-provider: missing type definition

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230929142852.578394-2-gatien.chevallier@xxxxxxxxxxx

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.


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:
