Subject: [net-next v2 00/12] add support for Renesas RZ/N1 ethernet subsystem devices
The Renesas RZ/N1 SoCs features an ethernet subsystem which contains
(most notably) a switch, two GMACs, and a MII converter [1]. This
series adds support for the switch and the MII converter.
The MII converter present on this SoC has been represented as a PCS
which sit between the MACs and the PHY. This PCS driver is probed from
the device-tree since it requires to be configured. Indeed the MII
converter also contains the registers that are handling the muxing of
ports (Switch, MAC, HSR, RTOS, etc) internally to the SoC.
The switch driver is based on DSA and exposes 4 ports + 1 CPU
management port. It include basic bridging support as well as FDB and
statistics support.

Changes in V2:
- PCS:
- Fix Reverse Christmas tree declaration
- Removed stray newline
- Add PCS remove function and disable clocks in them
- Fix miic_validate function to return correct values
- Split PCS CONV_MODE definition
- Reordered phylink_pcs_ops in definition order
- Remove interface setting in miic_link_up
- Remove useless checks for invalid interface/speed and error prints
- Replace phylink_pcs_to_miic_port macro by a static function
- Add comment in miic_probe about platform_set_drvdata
- Bindings:
- Fix wrong path for mdio.yaml $ref
- Fix yamllint errors
- Tag driver:
- Squashed commit that added tag value with tag driver
- Add BUILD_BUG_ON for tag size
- Split control_data2 in 2 16bits values
- Switch:
- Use .phylink_get_caps instead of .phylink_validate and fill
supported_interface correctly
- Use fixed size (ETH_GSTRING_LEN) string for stats and use memcpy
- Remove stats access locking since RTNL lock is used in upper layers
- Check for non C45 addresses in mdio_read/write and return
-EOPNOTSUPP
- Add get_eth_mac_stats, get_eth_mac_ctrl_stat, get_rmon_stats
- Fix a few indentation problems
- Remove reset callback from MDIO bus operation
- Add phy/mac/rmon stats
- Add get_rmon_stat to dsa_ops
