This sounds like the crystal feeding the PMIC, but the clock here should
be the signal that arrives at the CXO pin of the SoC.

Other than that, this looks good now.

Thanks,

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:
Error: Documentation/devicetree/bindings/clock/qcom,sm8550-tcsr.example.dts:23.29-30 syntax error
FATAL ERROR: Unable to parse input tree
make[1]: *** [scripts/Makefile.lib:406: Documentation/devicetree/bindings/clock/qcom,sm8550-tcsr.example.dtb] Error 1

make: *** [Makefile:1492: dt_binding_check] Error 2

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20221206125635.952114-2-abel.vesa@linaro.org

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.

Oups, I forgot to squash that part in.

Will send a new version.
