Since it is generic compatible string for both R-Car gen3 and RZ/G2 device, I would update the description as

- const: renesas,rcar-gen3-rpc-if # a generic R-Car gen3 or RZ/G2 device

Also may be we need to update the description of config RENESAS_RPCIF in drivers/memory/Kconfig to taken care of RZ/G2 devices in a separate patch.

Cheers,
Biju
