During a port FDB dump operation, the mutex protecting the concurrent
access to the switch registers is currently held by the internal
mv88e6xxx_port_db_dump and mv88e6xxx_port_db_dump_fid helpers.
It must be held at the higher level in mv88e6xxx_port_fdb_dump which
is called directly by DSA through ds->ops->port_fdb_dump. Fix this.

The first fact that needs to be stated is that the per-MAC settings in
SJA1105 called EGRESS and INGRESS do *not* disable egress and ingress on
the MAC. They only prevent non-link-local traffic from being
sent/received on this port.
So instead of having .phylink_mac_config essentially mess with the STP
state and force it to DISABLED/BLOCKING (which also brings useless
complications in sja1105_static_config_reload), simply add the
.phylink_mac_link_down and .phylink_mac_link_up callbacks which inhibit
TX at the MAC level, while leaving RX essentially enabled.
Also stop from trying to put the link down in .phylink_mac_config, which
is incorrect.

This enables the PTP support towards userspace applications such as
linuxptp.
The switches can timestamp only trapped multicast MAC frames, and
therefore only the profiles of 1588 over L2 are supported.
TX timestamping can be enabled per port, but RX timestamping is enabled
globally. As long as RX timestamping is enabled, the switch will emit
metadata follow-up frames that will be processed by the tagger. It may
be a problem that linuxptp does not restore the RX timestamping settings
when exiting.

Meta frame reception relies on the hardware keeping its promise that it
will send no other traffic towards the CPU port between a link-local
frame and a meta frame. Otherwise there is no other way to associate
the meta frame with the link-local frame it's holding a timestamp of.
The receive function is made stateful, and buffers a timestampable frame
until its meta frame arrives, then merges the two, drops the meta and
releases the link-local frame up the stack.

Without noticing any particular issue, this patch ensures that
management traffic is treated with the maximum priority on RX by the
switch. This is generally desirable, as the driver keeps a state
machine that waits for metadata follow-up frames as soon as a management
frame is received. Increasing the priority helps expedite the reception
(and further reconstruction) of the RX timestamp to the driver after the
MAC has generated it.

This will be used to keep state for RX timestamping. It is global
because the switch serializes timestampable and meta frames when

On TX, timestamping is performed synchronously from the
port_deferred_xmit worker thread.
In management routes, the switch is requested to take egress timestamps
(again partial), which are reconstructed and appended to a clone of the
skb that was just sent. The cloning is done by DSA and we retrieve the
pointer from the structure that DSA keeps in skb->cb.
Then these clones are enqueued to the socket's error queue for
application-level processing.

The design of this PHC driver is influenced by the switch's behavior
w.r.t. timestamping. It exposes two PTP counters, one free-running
(PTPTSCLK) and the other offset- and frequency-corrected in hardware
through PTPCLKVAL, PTPCLKADD and PTPCLKRATE. The MACs can sample either
of these for frame timestamps.
However, the user manual warns that taking timestamps based on the
corrected clock is less than useful, as the switch can deliver corrupted
timestamps in a variety of circumstances.
Therefore, this PHC uses the free-running PTPTSCLK together with a
timecounter/cyclecounter structure that translates it into a software
time domain. Thus, the settime/adjtime and adjfine callbacks are
hardware no-ops.
The timestamps (introduced in a further patch) will also be translated
to the correct time domain before being handed over to the userspace PTP
stack.
The introduction of a second set of PHC operations that operate on the
hardware PTPCLKVAL/PTPCLKADD/PTPCLKRATE in the future is somewhat
unavoidable, as the TTEthernet core uses the corrected PTP time domain.
However, the free-running counter + timecounter structure combination
will suffice for now, as the resulting timestamps yield a sub-50 ns
synchronization offset in steady state using linuxptp.
For this patch, in absence of frame timestamping, the operations of the
switch PHC were tested by syncing it to the system time as a local slave
clock with:
phc2sys -s CLOCK_REALTIME -c swp2 -O 0 -m -S 0.01

The incl_srcpt setting makes the switch mangle the destination MACs of
multicast frames trapped to the CPU - a primitive tagging mechanism that
works even when we cannot use the 802.1Q software features.
The downside is that the two multicast MAC addresses that the switch
traps for L2 PTP (01-80-C2-00-00-0E and 01-1B-19-00-00-00) quickly turn
into a lot more, as the switch encodes the source port and switch id
into bytes 3 and 4 of the MAC. The resulting range of MAC addresses
would need to be installed manually into the DSA master port's multicast
MAC filter, and even then, most devices might not have a large enough
MAC filtering table.
As a result, only limit use of incl_srcpt to when it's strictly
necessary: when under a VLAN filtering bridge. This fixes PTP in
non-bridged mode (standalone ports). Otherwise, PTP frames, as well as
metadata follow-up frames holding RX timestamps won't be received
because they will be blocked by the master port's MAC filter.
Linuxptp doesn't help, because it only requests the addition of the
unmodified PTP MACs to the multicast filter.
This issue is not seen in bridged mode because the master port is put in
promiscuous mode when the slave ports are enslaved to a bridge.
Therefore, there is no downside to having the incl_srcpt mechanism
active there.

This adds support for the Marvell 88E6250. I've checked that each
member in the ops-structure makes sense, and basic switchdev
functionality works fine.
It uses the new dual_chip option, and since its port registers start
at SMI address 0x08 or 0x18 (i.e., always sw_addr + 0x08), we need to
introduce a new compatible string in order for the auto-identification
in mv88e6xxx_detect() to work.
The chip has four per port 16-bits statistics registers, two of which
correspond to the existing "sw_in_filtered" and "sw_out_filtered" (but
at offsets 0x13 and 0x10 rather than 0x12 and 0x13, because why should
this be easy...). Wiring up those four statistics seems to require
introducing a STATS_TYPE_PORT_6250 bit or similar, which seems a tad
ugly, so for now this just allows access to the STATS_TYPE_BANK0 ones.
The chip does have ptp support, and the existing
mv88e6352_{gpio,avb,ptp}_ops at first glance seem like they would work
out-of-the-box, but for simplicity (and lack of testing) I'm eliding
this.

The mv88e6250 has a rather different way of reporting the link, speed
and duplex status. A simple difference is that the link bit is bit 12
rather than bit 11 of the port status register.
It gets more complicated for speed and duplex, which do not have
separate fields. Instead, there's a four-bit PortMode field, and
decoding that depends on whether it's a phy or mii port. For the phy
ports, only four of the 16 values have defined meaning; the rest are
called "reserved", so returning {SPEED,DUPLEX}_UNKNOWN seems
reasonable.
For the mii ports, most possible values are documented (0x3 and 0x5
are reserved), but I'm unable to make sense of them all. Since the
bits simply reflect the Px_MODE[3:0] configuration pins, just support
the subset that I'm certain about. Support for other setups can be
added later.

that "actual speed is determined by bit 8 above", and flipping back a
page, one finds that bits 13:8 are reserved...
So without further information on what bit 8 means, let's stick to
supporting just 10 and 100 Mbps on all ports.

These are almost identical to the 6185 variants, but have fewer bits
for the FID.
Bit 10 of the VTU_OP register (offset 0x05) is the VidPolicy bit,
which one should probably preserve in mv88e6xxx_g1_vtu_op(), instead
of always writing a 0. However, on the 6352 family, that bit is
located at bit 12 in the VTU FID register (offset 0x02), and is always
unconditionally cleared by the mv88e6xxx_g1_vtu_fid_write()
function.
Since nothing in the existing driver seems to know or care about that
bit, it seems reasonable to not add the boilerplate to preserve it for
the 6250 (which would require adding a chip-specific vtu_op function,
or adding chip-quirks to the existing one).

preferably double-checking both the data sheet and actual hardware in

The hardware values for link speed are held in the sja1105_speed_t enum.
However they do not increase in the order that sja1105_get_speed_cfg was
iterating over them (basically from SJA1105_SPEED_AUTO - 0 - to
SJA1105_SPEED_1000MBPS - 1 - skipping the other two).
Another bug is that the code in sja1105_adjust_port_config relies on the
fact that an invalid link speed is detected by sja1105_get_speed_cfg and
returned as -EINVAL. However storing this into an enum that only has
positive members will cast it into an unsigned value, and it will miss
the negative check.
So take the simplest approach and remove the sja1105_get_speed_cfg
function and replace it with a simple switch-case statement.

points to a function defined in sja1105_main.c), but it is what it is.
The FDB dump callback works for both families, hence no function pointer
for that.

Only a single dynamic configuration table of the SJA1105 P/Q/R/S
supports this operation: the FDB.
To keep the existing structure in place (sja1105_dynamic_config_read and
sja1105_dynamic_config_write) and not introduce any new function, a
convention is made for sja1105_dynamic_config_read that a negative index
argument denotes a search for the entry provided as argument.

This appends to the L2 Forwarding and L2 Forwarding Parameters tables
(originally added for first-generation switches) the bits that are new
in the second generation.

This was inadvertently copied from the SJA1105 E/T structure and not
tested. Cross-checking with the P/Q/R/S documentation (UM11040) makes
it immediately obvious what the correct bit offsets for this field are.

This structure is merely an implementation detail and should be hidden
from the sja1105_dynamic_config.h header, which provides to the rest of
the driver an abstract access to the dynamic configuration interface of
the switch.

When non-bridged, non-vlan'ed mv88e6xxx port is moving down, error
message is logged:
failed to kill vid 0081/0 for device eth_cu_1000_4
This is caused by call from __vlan_vid_del() with vin set to zero, over
call chain this results into _mv88e6xxx_port_vlan_del() called with
vid=0, and mv88e6xxx_vtu_get() called from there returns -EINVAL.
On symmetric path moving port up, call goes through
mv88e6xxx_port_vlan_prepare() that calls mv88e6xxx_port_check_hw_vlan()
that returns -EOPNOTSUPP for zero vid.
This patch changes mv88e6xxx_vtu_get() to also return -EOPNOTSUPP for
zero vid, then this error code is explicitly cleared in
dsa_slave_vlan_rx_kill_vid() and error message is no longer logged.

The phylink conflict was between a bug fix by Russell King
to make sure we have a consistent PHY interface mode, and
a change in net-next to pull some code in phylink_resolve()
into the helper functions phylink_mac_link_{up,down}()
On the dp83867 side it's mostly overlapping changes, with
the 'net' side removing a condition that was supposed to
trigger for RGMII but because of how it was coded never
actually could trigger.

Pull yet more SPDX updates from Greg KH:
"Here is another set of reviewed patches that adds SPDX tags to
different kernel files, based on a set of rules that are being used to
parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review
and analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers"
