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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Error: Documentation/devicetree/bindings/pci/ti,am65-pci-ep.example.dts:39.35-36 syntax error
FATAL ERROR: Unable to parse input tree
make[1]: *** [scripts/Makefile.lib:349: Documentation/devicetree/bindings/pci/ti,am65-pci-ep.example.dt.yaml] Error 1
make: *** [Makefile:1380: dt_binding_check] Error 2

See https://patchwork.ozlabs.org/patch/1458245

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.
