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:
Documentation/devicetree/bindings/input/touchscreen/cypress,tt21000.example.dts:37.26-39.19: Warning (unit_address_vs_reg): /example-0/i2c/touchscreen@24/button@0: node has a unit name, but no reg or ranges property
Documentation/devicetree/bindings/input/touchscreen/cypress,tt21000.example.dts:41.26-43.19: Warning (unit_address_vs_reg): /example-0/i2c/touchscreen@24/button@1: node has a unit name, but no reg or ranges property

Documentation/devicetree/bindings/input/touchscreen/cypress,tt21000.example.dt.yaml:0:0: /example-0/i2c/touchscreen@24: failed to match any schema with compatible: ['cypress,tt2100']

doc reference errors (make refcheckdocs):


This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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

pip3 install dtschema --upgrade

Please check and re-submit.
