I fixed this.

I moved this.

This should have both groups and group.

This should have groups as compulsory.

Actually not in this case.
There was an error in commit 3af50e548019f6ee26d0ed4340f4ab980f884696
"dt-bindings: pinctrl: Convert generic pin mux and config properties to schema"
A function has a 1-to-many relationship to groups so it should be "groups"
for the multiplexing (pluralis).
A pin config on the other hand, such as "set slewrate for all the pins in
this pin group" has a 1-to-1 relationship to a group (singularis).
I am trying to fix it all up in one patch.
Yours,
