Merge branch 'renesas-eswitch'
Yoshihiro Shimoda says: ==================== 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 upstream. Changes from v6: https://lore.kernel.org/all/20221028065458.2417293-1-yoshihiro.shimoda.uh@renesas.com/ - 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: https://lore.kernel.org/all/20221027134034.2343230-1-yoshihiro.shimoda.uh@renesas.com/ - Add maxItems for the ethernet-port/port/reg property. Changes from v4: https://lore.kernel.org/all/20221019083518.933070-1-yoshihiro.shimoda.uh@renesas.com/ - 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). ==================== Signed-off-by: David S.
