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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
./Documentation/devicetree/bindings/display/ilitek,ili9163.yaml: $id: relative path/filename doesn't match actual path or filename
	expected: http://devicetree.org/schemas/display/ilitek,ili9163.yaml#
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/ilitek,ili9163.yaml: duplicate '$id' value 'http://devicetree.org/schemas/display/ilitek,ili9486.yaml#'

See https://patchwork.ozlabs.org/patch/1456455

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
date:

pip3 install dtschema --upgrade

Please check and re-submit.
