Not all combinations are possible. In fact, there is a limited choice
for each value. So consider getting the yaml tools to help you by
listing what is valid for each setting. You might need a different
format than. Also, this format it is not clear what each value refers
to.

renesas,miic-port-connection-mii-conv1 = <PORTIN_GMAC2>;
renesas,miic-port-connection-mii-conv2 = <MAC2>;
renesas,miic-port-connection-mii-conv3 = <SWITCH_PORTC>;
renesas,miic-port-connection-mii-conv4 = <SWITCH_PORTB>;
renesas,miic-port-connection-mii-conv5 = <SWITCH_PORTA>;

is more sense documenting, and i suspect easier to make the validator
work for you.
