For backwards compatibility, the "impossible" modes that claim to have a delay on the PCB are still accepted, but trigger a warning message. As Andrew suggested, I have also added a checkpatch check that requires a comment for any RGMII mode that is not "rgmii-id". No Device Trees are updated to avoid the warning for now, to give other projects syncing the Linux Device Trees some time to fix their drivers as well. I intend to submit an equivalent change for U-Boot's am65-cpsw-nuss driver as soon as the changes are accepted for Linux.
