Subject: [PATCH] net: dsa: ocelot: add driver for Felix switch family
|
|
|
|
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.
