How many? (maxItems: 1)

This literally requires a node called 'child-node'. Not what you want.
You need a $ref to the multi-color schema in here and then only define
what's specific to this chip.

What is reg then? Some made up index? Can't you do:
reg = <1 2 3>;
led@1 {};
led@2 {};
led@2 {};

Have you read this file recently? Don't add new references to it. (And
generally freeform references to other files are wrong with schemas).
