This is already documented in goodix,gt7375p.yaml. Now linux-next has warnings:

/builds/robherring/linux-dt/Documentation/devicetree/bindings/input/goodix,gt7986u.example.dtb:
touchscreen@0: compatible: 'oneOf' conditional failed, one must be
fixed:
['goodix,gt7986u'] is too short

from schema $id:

Please sort this out and send a fix.
