Subject: [PATCH v7 0/3] net: ethernet: renesas: Add support for "Ethernet Switch"

This patch series is based on next-20221027.

Add initial support for Renesas "Ethernet Switch" device of R-Car S4-8.
The hardware has features about forwarding for an ethernet switch
device. But, for now, it acts as ethernet controllers so that any
forwarding offload features are not supported. So, any switchdev
header files and DSA framework are not used.

Notes that this driver requires some special settings on marvell10g,
Especially host mactype and host speed. And, I need further investigation
to modify the marvell10g driver for upstream. But, the special settings
are applied, this rswitch driver can work correcfly without any changes
of this rswitch driver. So, I believe the rswitch driver can go for

Changes from v6:
 - Add Reviewed-by tag in the patch [1/3].
 - Fix ordering of initialization because NFS root can start mounting
   the filesystem before register_netdev() even returns

Changes from v5:
 - Add maxItems for the ethernet-port/port/reg property.

Changes from v4:
 - Rebased on next-20221027.
 - Drop some unneeded properties on the dt-bindings doc.
 - Change the subject and commit descriptions on the patch [2/3].
 - Use phylink instead of phylib.
 - Modify struct rswitch_*_desc to remove similar functions ([gs]et_dptr).
