From our experience with Renesas R-Car, we concluded to have a binding
for the SoC and one for the family it belongs to.

For example, the already upstream watchdog bindings:

- items:
- enum:
- renesas,r9a06g032-wdt # RZ/N1D
- const: renesas,rzn1-wdt # RZ/N1

I could add the comments here as well if that helps?
