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

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/power/supply/bq256xx.example.dt.yaml: battery: 'termination-current-microamp' does not match any of the regexes: '^ocv-capacity-table-[0-9]+$', 'pinctrl-[0-9]+'
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/power/supply/battery.yaml


See https://patchwork.ozlabs.org/patch/1353535

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.
