Due to other errors you never reached the poart that checks the example.
I use the following to focus on a single binding:

(from my script, but you get the idea)

domake ${arch} ${config} dt_binding_check DT_SCHEMA_FILES=${bindings}/display/panel/feixin,k101-im2ba02.yaml

In this way I can ignore all the bindings that otherwise fails.

Note: I sometimes have to clean my ouput directory to force that the
examples are tested.

It is also a good idea to introduce errors on purpose in the example, in
this way you can check that they are tested.
