My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230726090129.233316-1-gatien.chevallier@foss.st.com
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.
Introduce a STM32 firewall framework that offers to firewall consumers
different firewall services such as the ability to check their access
rights against their firewall controller(s).
The STM32 firewall framework offers a generic API for STM32 firewall
controllers that is defined in their drivers to best fit the
specificity of each firewall.
There are various types of firewalls:
-Peripheral firewalls that filter accesses to peripherals
-Memory firewalls that filter accesses to memories or memory regions
-No type for undefined type of firewall

Changes in V2:
- Support multiple entries for "feature-domains"
property. Change stm32_firewall_get_firewall()
to do so.
- Better handle the device-tree parsing using
phandle+args APIs and phandle iterator.
- Remove "resource firewall" type
- Rephrase STM32_FIREWALL description in the bus
Kconfig and remove useless default value
- Add missing EXPORT_SYMBOL_GPL
- Remove useless stm32_firewall_get_id() API
- Add a field for the name of the firewall entry
in the stm32_firewall_controller structure
- Minor fixes on some traces level (err -> debug)
- Fix licenses to GPL-2.0-only
- Fix stm32_firewall_get_firewall() description
- Rephrase some sentences to better emphasize this
is STM32-specific
- Switch to list_for_each_entry() in
stm32_firewall_controller_unregister() as we only
expect one firewall controller instance per device.
The loop just breaks when found
- Do not register the firewall controller if it is
already registered to the framework

2.25.1ETZPC is a firewall controller. Put all peripherals filtered by the
ETZPC as ETZPC subnodes and reference ETZPC as a
feature-domain-controller.
For more information on which peripheral is securable or supports MCU
isolation, please read the STM32MP15 reference manual.

2.25.1ETZPC is a firewall controller. Put all peripherals filtered by the
ETZPC as ETZPC subnodes and reference ETZPC as a
feature-domain-controller.
For more information on which peripheral is securable or supports MCU
isolation, please read the STM32MP13 reference manual.
