Rob,

As I'm preparing some upstream patches for kirin-pcie driver to support
Hikey 970, I opted to try first to convert the existing schema to yaml.

It should be noticed that those two patches currently won't pass
cleanly with dtbs_check/dt_binding_check.

I'm out of ideas about how to fix. It sounds to me that the checking
tools are trying to enforce different types of reference types than
the ones used by designware drivers.:

	From schema: /devel/v4l/hikey970/Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.yaml

I ran out of ideas about how to solve that. So, I'm posting it as a RFC.
