Because ilitek, ili2901 needs to use reset to pull down the time for 10ms,
so we need to control the reset, use this drive control.

1. You are adding fallback which was not explained in commit msg.

2. What's more, this was not tested. Please test your code before sending...

3. Plus you did not Cc maintainers, so I suspect you work on some
ancient tree...

Best regards,
Krzysztof

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:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/input/elan,ekth6915.example.dtb: touchscreen@10: compatible: ['elan,ekth6915'] is too short
	from schema $id: http://devicetree.org/schemas/input/elan,ekth6915.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231225092843.5993-2-xiazhengqiao@huaqin.corp-partner.google.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.
