FTR, this is postponed until after v6.4-rc1, when commit a0340df7eca4f28e ("can:
rcar_canfd: Add transceiver support") has landed upstream.
Else the following message is printed (_after_ rcar_canfd is probed):

    rcar_canfd e6660000.can: Failed to create device link (0x180) with can-phy0

when I'm talking to journalists I just say "programmer" or something like that.
