This short series adds support for the RZ/N1 Expansion Board. This board
is a carrier board on which a daughter board (either RZ/N1D or RZ/N1S)
can be plugged. The device-tree that is added by this series enables the
use to the 2 external switch ports that are present on this board.

The EB board (Expansion board) supports both RZ/N1D and RZ-N1S. Since this
configuration targets only the RZ/N1D, it is named r9a06g032-rzn1d400-eb.
It adds support for the 2 additional switch ports (port C and D) that are
available on that board.

Don't you want to have "renesas,rzn1d400-db", too, in between the two
other values?

No underscores in node names, unless you override existing node with
such underscore.

Do you mean like that ?
- enum:
- renesas,rzn1d400-eb # RZN1D-EB (Expansion Board when using a
RZN1D-DB)
- const: renesas,rzn1d400-db
- const: renesas,r9a06g032
And thus using compatible = "renesas,rzn1d400-eb",
"renesas,rzn1d400-db", "renesas,r9a06g032" in the EB dt I guess.
