you have errors that you need to address. once the patch gets to
mainline master branch, then we can consider this patch.
Also in the future, when there is dependency such as these, you should
indicate that in the diffstat section rather than expecting maintainers
to go searching (we wont).

Sorry, but no.
please convert
Documentation/devicetree/bindings/gpio/gpio-tpic2810.txt to yaml
prior to any patches that enable it. (dtbs_check should have already
warned you about this).

A patch for changing binding to yaml has already been sent.
