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

Documentation/devicetree/bindings/bus/stm32/st,stm32-etzpc.example.dts:17.5-24.11: Warning (unit_address_vs_reg): /example-0/soc: node has a reg or ranges property, but no unit name

See https://patchwork.ozlabs.org/patch/1273431

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.
