Your patches aren't bisectable. It's fine if you want to combine patch 1 
and 2 into 1 patch. Or just use the raw numbers here instead of the 
header.

I'd prefer if you used raw ids or even fake node for the example, like
<&pll_in> and <&mpll_in> for readability, rather than combining the patches

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:

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231010062917.3624223-2-xianwei.zhao@amlogic.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.
