Re: [PATCH v2 01/72] dt-bindings: media: Deprecate clock-frequency property for camera sensors

On Wed, 13 Aug 2025 00:45:09 +0300, Laurent Pinchart wrote:

Usage of the clock-frequency property for camera sensors is discouraged
in favour of using assigned-clock-rates (and assigned-clock-parents
where needed). Mark the property as deprecated.

Update the examples accordingly. In DT examples where the sensor input
clock appears to come from a programmable clock generator, replace
clock-frequency by the assigned-clocks and assigned-clock-rates
properties. Otherwise, just drop clock-frequency.

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.
