[PATCH v2 net-next 00/11] DSA driver for Vitesse Felix switch

[PATCH v2 net-next 00/11] DSA driver for Vitesse Felix switch

[Vladimir Oltean]

This series builds upon the previous "Accomodate DSA front-end into
Ocelot" topic and does the following:

- Reworks the Ocelot (VSC7514) driver to support one more switching core
  (VSC9959), used in NPI mode. Some code which was thought to be
  SoC-specific (ocelot_board.c) wasn't, and vice versa, so it is being
  accordingly moved.
- Exports ocelot driver structures and functions to include/soc/mscc.
- Adds a DSA ocelot front-end for VSC9959, which is a PCI device and
  uses the exported ocelot functionality for hardware configuration.
- Adds a tagger driver for the Vitesse injection/extraction DSA headers.
  This is known to be compatible with at least Ocelot and Felix.

[PATCH v2 net-next 01/11] net: mscc: ocelot: move resource ioremap and regmap init to common code

[Vladimir Oltean]

From: Claudiu Manoil <claudiu.manoil@nxp.com>

Let's make this ioremap and regmap init code common.  It should not
be platform dependent as it should be usable by PCI devices too.
Use better names where necessary to avoid clashes.

[PATCH v2 net-next 02/11] net: mscc: ocelot: filter out ocelot SoC specific PCS config from common path

[Vladimir Oltean]

From: Claudiu Manoil <claudiu.manoil@nxp.com>

The adjust_link routine should be generic enough to be (re)used by
any SoC that integrates a switch core compatible with the Ocelot
core switch driver.  Currently all configurations are generic except
for the PCS settings that are SoC specific.  Move these out to the
Ocelot SoC/board instance.

[PATCH v2 net-next 03/11] net: mscc: ocelot: move invariant configs out of adjust_link

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

It doesn't make sense to rewrite all these registers every time the PHY
library notifies us about a link state change.

In a future patch we will customize the MTU for the CPU port, and since
the MTU was previously configured from adjust_link, if we don't make
this change, its value would have got overridden.

[PATCH v2 net-next 04/11] net: mscc: ocelot: create a helper for changing the port MTU

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

Since in an NPI/DSA setup, not all ports will have the same MTU, we need
to make sure the watermarks for pause frames and/or tail dropping logic
that existed in the driver is still coherent for the new MTU values.

We need to do this because the NPI (aka external CPU) port needs an
increased MTU for the DSA tag. This will be done in a future patch.

[PATCH v2 net-next 06/11] net: mscc: ocelot: adjust MTU on the CPU port in NPI mode

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

When using the NPI port, the DSA tag is passed through Ethernet, so the
switch's MAC needs to accept it as it comes from the DSA master. Increase
the MTU on the external CPU port to account for the length of the
injection header.

Without this patch, MTU-sized frames are dropped by the switch's CPU
port on xmit, which is especially obvious in TCP sessions.

[PATCH v2 net-next 09/11] net: mscc: ocelot: publish ocelot_sys.h to include/soc/mscc

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

The Felix DSA driver needs to write to SYS_RAM_INIT_RAM_INIT for its own
chip initialization process.

Also update the MAINTAINERS file such that the headers exported by the
ocelot driver are under the same maintainers' umbrella as the driver
itself.

[PATCH v2 net-next 10/11] net: dsa: ocelot: add tagger for Ocelot/Felix switches

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

While it is entirely possible that this tagger format is in fact more
generic than just these 2 switch families, I don't have that knowledge.
The Seville switch in NXP T1040 has a similar frame format, but there
are enough differences (e.g. DEST field starts at bit 57 instead of 56)
that calling this file tag_vitesse.c is a bit of a stretch at the
moment. The frame format has been listed in a comment so that people who
add support for further Vitesse switches can rework this tagger while
keeping compatibility with Felix.

The "ocelot" name was chosen instead of "felix" because even the Ocelot
switch can act as a DSA device when it is used in NPI mode, and the Felix
tagger format is almost identical. Currently it is only used for the
Felix switch embedded in the NXP LS1028A chip.

The ABI for this tagger should be considered "not stable" at the moment.
The DSA tag is always placed before the Ethernet header and therefore,
we are using the long prefix for RX tags to avoid putting the DSA master
port in promiscuous mode. Once there will be an API in DSA for drivers
to request DSA masters to be in promiscuous mode unconditionally, we
will switch to the "no prefix" extraction frame header, which will save
16 padding bytes for each RX frame.

Changes in v2:
Reordered this patch so it predates the introduction of the Felix driver
which uses it.

[PATCH v2 net-next 11/11] net: dsa: ocelot: add driver for Felix switch family

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

This supports an Ethernet switching core from Vitesse / Microsemi /
Microchip (VSC9959) which is part of the Ocelot family (a brand name),
and whose code name is Felix. The switch can be (and is) integrated on
different SoCs as a PCIe endpoint device.

The functionality is provided by the core of the Ocelot switch driver
(drivers/net/ethernet/mscc). In this regard, the current driver is an
instance of Microsemi's Ocelot core driver, with a DSA front-end. It
inherits its name from VSC9959's code name, to distinguish itself from
the switchdev ocelot driver.

The patch adds the logic for probing a PCI device and defines the
register map for the VSC9959 switch core, since it has some differences
in register addresses and bitfield mappings compared to the other Ocelot
switches (VSC7511, VSC7512, VSC7513, VSC7514).

The Felix driver declares the register map as part of the "instance
table". Currently the VSC9959 inside NXP LS1028A is the only instance,
but presumably it can support other switches in the Ocelot family, when
used in DSA mode (Linux running on the external CPU, and not on the
embedded MIPS).

In a few cases, some h/w operations have to be done differently on
VSC9959 due to missing bitfields.  This is the case for the switch core
reset and init.  Because for this operation Ocelot uses some bits that
are not present on Felix, the latter has to use a register from the
global registers block (GCB) instead.

Although it is a PCI driver, it relies on DT bindings for compatibility
with DSA (CPU port link, PHY library). It does not have any custom
device tree bindings, since we would like to minimize its dependency on
device tree though.

Changes in v2:
- Dropped the "vitesse" folder (and the movement of the vsc73xx driver)
  due to popular demand
- Put the driver in an "ocelot" folder, to appease further people who
  may want to add a driver for VSC7511. There is enough flexibility that
  such driver might be added either in felix, or in parallel to it,
  without moving too many things around.
- Reordered/renamed the Kconfig options to appear as alphabetically
  sorted in menuconfig.
- Replaced the "felix_ls1028a" string with "vsc9959".
- Added "regfields" element to struct felix_info.
- Renamed felix-regs.c to felix_vsc9959.c
- Moved felix_init_structs from felix_vsc9959.c to felix.c
- Reworded commit message
