Merge branch 'add-sparx5i-driver'

Steen Hegelund says:

====================
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()
