Adding the Sparx5i Switch Driver

This series provides the Microchip Sparx5i Switch Driver

The SparX-5 Enterprise Ethernet switch family provides a rich set of
Enterprise switching features such as advanced TCAM-based VLAN and QoS
processing enabling delivery of differentiated services, and security
through TCAMbased frame processing using versatile content aware processor
(VCAP). IPv4/IPv6 Layer 3 (L3) unicast and multicast routing is supported
with up to 18K IPv4/9K IPv6 unicast LPM entries and up to 9K IPv4/3K IPv6
(S,G) multicast groups. L3 security features include source guard and
reverse path forwarding (uRPF) tasks. Additional L3 features include
VRF-Lite and IP tunnels (IP over GRE/IP).

The SparX-5 switch family features a highly flexible set of Ethernet ports
with support for 10G and 25G aggregation links, QSGMII, USGMII, and
USXGMII.  The device integrates a powerful 1 GHz dual-core ARM® Cortex®-A53
CPU enabling full management of the switch and advanced Enterprise
applications.

The SparX-5 switch family targets managed Layer 2 and Layer 3 equipment in
SMB, SME, and Enterprise where high port count 1G/2.5G/5G/10G switching
with 10G/25G aggregation links is required.

The SparX-5 switch family consists of following SKUs:

  VSC7546 SparX-5-64 supports up to 64 Gbps of bandwidth with the following
  primary port configurations.
   - 6 ×10G
   - 16 × 2.5G + 2 × 10G
   - 24 × 1G + 4 × 10G

  VSC7549 SparX-5-90 supports up to 90 Gbps of bandwidth with the following
  primary port configurations.
   - 9 × 10G
   - 16 × 2.5G + 4 × 10G
   - 48 × 1G + 4 × 10G

  VSC7552 SparX-5-128 supports up to 128 Gbps of bandwidth with the
  following primary port configurations.
   - 12 × 10G
   - 6 x 10G + 2 x 25G
   - 16 × 2.5G + 8 × 10G
   - 48 × 1G + 8 × 10G

  VSC7556 SparX-5-160 supports up to 160 Gbps of bandwidth with the
  following primary port configurations.
   - 16 × 10G
   - 10 × 10G + 2 × 25G
   - 16 × 2.5G + 10 × 10G
   - 48 × 1G + 10 × 10G

  VSC7558 SparX-5-200 supports up to 200 Gbps of bandwidth with the
  following primary port configurations.
   - 20 × 10G
   - 8 × 25G

In addition, the device supports one 10/100/1000/2500/5000 Mbps
SGMII/SerDes node processor interface (NPI) Ethernet port.

Time sensitive networking (TSN) is supported through a comprehensive set of
features including frame preemption, cut-through, frame replication and
elimination for reliability, enhanced scheduling: credit-based shaping,
time-aware shaping, cyclic queuing, and forwarding, and per-stream policing
and filtering.

Together with IEEE 1588 and IEEE 802.1AS support, this guarantees
low-latency deterministic networking for Industrial Ethernet.

The Sparx5i support is developed on the PCB134 and PCB135 evaluation boards.

- PCB134 main networking features:
  - 12x SFP+ front 10G module slots (connected to Sparx5i through SFI).
  - 8x SFP28 front 25G module slots (connected to Sparx5i through SFI high
    speed).
  - Optional, one additional 10/100/1000BASE-T (RJ45) Ethernet port
    (on-board VSC8211 PHY connected to Sparx5i through SGMII).

- PCB135 main networking features:
  - 48x1G (10/100/1000M) RJ45 front ports using 12xVSC8514 QuadPHY’s each
    connected to VSC7558 through QSGMII.
  - 4x10G (1G/2.5G/5G/10G) RJ45 front ports using the AQR407 10G QuadPHY
    each port connects to VSC7558 through SFI.
  - 4x SFP28 25G module slots on back connected to VSC7558 through SFI high
    speed.
  - Optional, one additional 1G (10/100/1000M) RJ45 port using an on-board
    VSC8211 PHY, which can be connected to VSC7558 NPI port through SGMII
    using a loopback add-on PCB)

This series provides support for:
  - SFPs and DAC cables via PHYLINK with a number of 5G, 10G and 25G
    devices and media types.
  - Port module configuration for 10M to 25G speeds with SGMII, QSGMII,
    1000BASEX, 2500BASEX and 10GBASER as appropriate for these modes.
  - SerDes configuration via the Sparx5i SerDes driver (see below).
  - Host mode providing register based injection and extraction.
  - Switch mode providing MAC/VLAN table learning and Layer2 switching
    offloaded to the Sparx5i switch.
  - STP state, VLAN support, host/bridge port mode, Forwarding DB, and
    configuration and statistics via ethtool.

More support will be added at a later stage.

The Sparx5i Chip Register Model can be browsed at this location:
https://github.com/microchip-ung/sparx-5_reginfo
and the datasheet is available here:
https://ww1.microchip.com/downloads/en/DeviceDoc/SparX-5_Family_L2L3_Enterprise_10G_Ethernet_Switches_Datasheet_00003822B.pdf

The series depends on the following series currently on their way
into the kernel:

- 25G Base-R phy mode
  Link: https://lore.kernel.org/r/20210611125453.313308-1-steen.hegelund@microchip.com/
- Sparx5 Reset Driver
  Link: https://lore.kernel.org/r/20210416084054.2922327-1-steen.hegelund@microchip.com/

ChangeLog:
v5:
    - cover letter
        - updated the description to match the latest data sheets
    - basic driver
        - added error message in case of reset controller error
        - port struct: replacing has_sfp with inband, adding pause_adv
    - host mode
        - port cleanup: unregisters netdevs and then removes phylink etc
        - checking for pause_adv when comparing port config changes
        - getting duplex and pause state in the link_up callback.
        - getting inband, autoneg and pause_adv config in the pcs_config
          callback.
    - port
        - use only the pause_adv bits when getting aneg status
        - use the inband state when updating the PCS and port config
v4:
    - basic driver:
        Using devm_reset_control_get_optional_shared to get the reset
        control, and let the reset framework check if it is valid.
    - host mode (phylink):
        Use the PCS operations to get state and update configuration.
        Removed the setting of interface modes.  Let phylink control this.
        Using the new 5gbase-r and 25gbase-r modes.
        Using a helper function to check if one of the 3 base-r modes has
        been selected.
        Currently it will not be possible to change the interface mode by
        changing the speed (e.g via ethtool).  This will be added later.
v3:
    - basic driver:
        - removed unneeded braces
        - release reference to ports node after use
        - use dev_err_probe to handle DEFER
        - update error value when bailing out (a few cases)
        - updated formatting of port struct and grouping of bool values
        - simplified the spx5_rmw and spx5_inst_rmw inline functions
    - host mode (netdev):
        - removed lockless flag
        - added port timer init
    - host mode (packet - manual injection):
        - updated error counters in error situations
        - implemented timer handling of watermark threshold: stop and
          restart netif queues.
        - fixed error message handling (rate limited)
        - fixed comment style error
        - used DIV_ROUND_UP macro
        - removed a debug message for open ports

v2:
    - Updated bindings:
        - drop minItems for the reg property
    - Statistics implementation:
        - Reorganized statistics into ethtool groups:
            eth-phy, eth-mac, eth-ctrl, rmon
          as defined by the IEEE 802.3 categories and RFC 2819.
        - The remaining statistics are provided by the classic ethtool
          statistics command.
    - Hostmode support:
        - Removed netdev renaming
        - Validate ethernet address in sparx5_set_mac_address()
