[PATCH] dt-bindings: clock: ti,clockdomain: Convert to DT schema

[PATCH] dt-bindings: clock: ti,clockdomain: Convert to DT schema

[Bhargav Joshi]

Convert TI clockdomain to yaml DT schema. Drop '#clock-cells' from the
required list as this binding doesn't define a new clock binding type,
it is used to group existing clock nodes under hardware hierarchy. Most
existing dts omit '#clock-cells'.

-Binding for Texas Instruments clockdomain.
-
-This binding uses the common clock binding[1] in consumer role.
-Every clock on TI SoC belongs to one clockdomain, but software
-only needs this information for specific clocks which require
-their parent clockdomain to be controlled when the clock is
-enabled/disabled. This binding doesn't define a new clock
-binding type, it is used to group existing clock nodes under
-hardware hierarchy.

-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : shall be "ti,clockdomain"
-- #clock-cells : from common clock binding; shall be set to 0.
-- clocks : link phandles of clocks within this domain
-
-Optional properties:
-- clock-output-names : from common clock binding.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):
Warning: Documentation/devicetree/bindings/clock/ti/ti,gate-clock.yaml references a file that doesn't exist: Documentation/devicetree/bindings/clock/ti/clockdomain.txt
Documentation/devicetree/bindings/clock/ti/ti,gate-clock.yaml: Documentation/devicetree/bindings/clock/ti/clockdomain.txt

See https://patchwork.kernel.org/project/devicetree/patch/20260621-ti-clockdomain-v1-1-e99a56af98ea@gmail.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.
