The '2.0' in the compatible string refers to a revision of the converter 
IP. Wouldn't a single yaml be used to describe multiple revisions of the 
IP, like net/snps,dwmac.yaml? Having the revision number in the filename 
appears to be unusual.

I am very surprised by this typo; so, I rechecked. I used the command, 
make dt_binding_check DT_SCHEMA_FILES=altr,gmii-to-sgmii.yaml, which did 
not report an error, but I did confirm the bot's error with the command, 
make dt_binding_check. I will be sure to run the full 'make 
dt_binding_check' before submitting.

Thanks for the feedback,

Matthew Gerlach
