I can see that other examples also reference bindings from external
drivers, otherwise I think it would throw an error for not being able to
find the parents in properties such as, resets and clocks. I tried to
update my dtschema to ensure that this failure was not missed.
I checked and made sure that no errors were not seen, so I started to
wonder if maybe when this series was submitted the qcom,sm8750-gcc.h wasn't
yet present on the kernel tree. To confirm this, I removed the
aforementioned header file, and got the same error/issue. Now that the
sm8750 gcc header has landed upstream, I believe that this error should be
resolved.
Thanks
