The series adds display support for the stm32f769-disco board. It has been
tested on hardware revisions MB1225-B03 and MB1166-A09. This required
modifications to the nt35510 driver. As I do not have the Hydis HVA40WV1
display, it would be better if someone tested the driver in that
configuration.

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

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231229135154.675946-6-dario.binacchi@amarulasolutions.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.

You need a dash in from of each "items:" for that to work.
