7ebe52f555 docs: change the title of networking docs
The current title of our section of the documentation is
Linux Networking Documentation. Since we're describing
a section of Linux Documentation repeating those two
words seems redundant.

1f77204e11 dt-bindings: net: adin: document phy clock output properties
The ADIN1300 supports generating certain clocks on its GP_CLK pin, as
well as providing the reference clock on CLK25_REF.

Add DT properties to configure both pins.

Technically the phy also supports a recovered 125MHz clock for
synchronous ethernet. However SyncE should be configured dynamically at
runtime, so it is explicitly omitted in this binding.

32d0efabee dt-bindings: net: marvell,orion-mdio: Set unevaluatedProperties to false
When the binding was converted it appeared necessary to set
'unevaluatedProperties: true' because of the switch devices on the
turris-mox board. Actually the error was because of the reg property
being incorrect causing the rest of the properties to be unevaluated.

After the reg properties are fixed for turris-mox we can set
'unevaluatedProperties: false' as is generally expected.

ba3e2eaef1 docs: ctucanfd: Use 'kernel-figure' directive instead of 'figure'
Two issues were observed in the ReST doc added by commit c3a0addefb
("docs: ctucanfd: CTU CAN FD open-source IP core documentation.")
with Sphinx versions 2.4.4 and 4.5.0.

The plain "figure" directive broke "make pdfdocs" due to a missing
PDF figure.  For conversion of SVG -> PDF to work, the "kernel-figure"
directive, which is an extension for kernel documentation, should
be used instead.

The directive of "code:: raw" causes a warning from both
"make htmldocs" and "make pdfdocs", which reads:

    [...]/can/ctu/ctucanfd-driver.rst:75: WARNING: Pygments lexer name
    'raw' is not known

A plain literal-block marker should suffice where no syntax
highlighting is intended.

Fix the issues by using suitable directive and marker.

Fixes: c3a0addefb ("docs: ctucanfd: CTU CAN FD open-source IP core documentation.")

commit 68822bdf76 ("net: generalize skb freeing
deferral to per-cpu lists") added another per-cpu
cache of skbs. It was expected to be small,
and an IPI was forced whenever the list reached 128
skbs.

We might need to be able to control more precisely
queue capacity and added latency.

An IPI is generated whenever queue reaches half capacity.

Default value of the new limit is 64.

a7931ac161 dt-bindings: net: renesas,etheravb: Document RZ/V2M SoC
Document the Ethernet AVB IP found on RZ/V2M SoC.
It includes the Ethernet controller (E-MAC) and Dedicated Direct memory
access controller (DMAC) for transferring transmitted Ethernet frames
to and received Ethernet frames from respective storage areas in the
RAM at high speed.
The AVB-DMAC is compliant with IEEE 802.1BA, IEEE 802.1AS timing and
synchronization protocol, IEEE 802.1Qav real-time transfer, and the
IEEE 802.1Qat stream reservation protocol.

R-Car has a pair of combined interrupt lines:
 ch22 = Line0_DiA | Line1_A | Line2_A
 ch23 = Line0_DiB | Line1_B | Line2_B
Line0 for descriptor interrupts (which we call dia and dib).
Line1 for error related interrupts (which we call err_a and err_b).
Line2 for management and gPTP related interrupts (mgmt_a and mgmt_b).

RZ/V2M hardware has separate interrupt lines for each of these.

It has 3 clocks; the main AXI clock, the AMBA CHI (Coherent Hub
Interface) clock and a gPTP reference clock.

====================
Netfilter updates for net-next

This is v2 including deadlock fix in conntrack ecache rework
reported by Jakub Kicinski.

The following patchset contains Netfilter updates for net-next,
mostly updates to conntrack from Florian Westphal.

1) Add a dedicated list for conntrack event redelivery.

2) Include event redelivery list in conntrack dumps of dying type.

3) Remove per-cpu dying list for event redelivery, not used anymore.

4) Add netns .pre_exit to cttimeout to zap timeout objects before
   synchronize_rcu() call.

5) Remove nf_ct_unconfirmed_destroy.

6) Add generation id for conntrack extensions for conntrack
   timeout and helpers.

7) Detach timeout policy from conntrack on cttimeout module removal.

8) Remove __nf_ct_unconfirmed_destroy.

9) Remove unconfirmed list.

10) Remove unconditional local_bh_disable in init_conntrack().

11) Consolidate conntrack iterator nf_ct_iterate_cleanup().

12) Detect if ctnetlink listeners exist to short-circuit event
    path early.

13) Un-inline nf_ct_ecache_ext_add().

14) Add nf_conntrack_events autodetect ctnetlink listener mode
    and make it default.

15) Add nf_ct_ecache_exist() to check for event cache extension.

16) Extend flowtable reverse route lookup to include source, iif,
    tos and mark, from Sven Auhagen.

17) Do not verify zero checksum UDP packets in nf_reject,
    from Kevin Mitchell.

90d1daa458 netfilter: conntrack: add nf_conntrack_events autodetect mode
This adds the new nf_conntrack_events=2 mode and makes it the
default.

This leverages the earlier flag in struct net to allow to avoid
the event extension as long as no event listener is active in
the namespace.

This avoids, for most cases, allocation of ct->ext area.
A followup patch will take further advantage of this by avoiding
calls down into the event framework if the extension isn't present.

caf83e494d dt-bindings: Drop redundant 'maxItems/minItems' in if/then schemas
Another round of removing redundant minItems/maxItems when 'items' list is
specified. This time it is in if/then schemas as the meta-schema was
failing to check this case.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

b2b701b31e dt-bindings: pinctrl: Allow values for drive-push-pull and drive-open-drain
A few platforms, at91 and tegra, use drive-push-pull and
drive-open-drain with a 0 or 1 value. There's not really a need for values
as '1' should be equivalent to no value (it wasn't treated that way) and
drive-push-pull disabled is equivalent to drive-open-drain. So dropping the
value can't be done without breaking existing OSs. As we don't want new
cases, mark the case with values as deprecated.

00fd24089b dt: bindings: net: add bindings of WCN6750 for ath11k
WCN6750 is the WLAN chip on Qualcomm Snapdragon SoC SC7280;
Though being a PCIe based solution, it is not attached to
the APSS processor (Application Processor SubSystem), it is
instead attached to another tiny processor called WPSS Q6
processor (Wireless Processor SubSystem) on the SC7280 MSM,
where the WLAN firmware runs, and it is the WLAN firmware
running on the Q6 processor which enumerates WCN6750, as a
result APPS processor would never know such a device being
present in the system and would not detect the WCN6750
hardware unless and otherwise WCN6750 is registered as a
platform device. This is the reason behind adding WCN6750
WLAN node in the device tree.

Add WCN6750 wireless driver support, its based on ath11k driver.

49714461b7 dt-bindings: net: phy: Add 10-baseT1L 2.4 Vpp
Add a tristate property to advertise desired transmit level.

If the device supports the 2.4 Vpp operating mode for 10BASE-T1L,
as defined in 802.3gc, and the 2.4 Vpp transmit voltage operation
is desired, property should be set to 1. This property is used
to select whether Auto-Negotiation advertises a request to
operate the 10BASE-T1L PHY in increased transmit level mode.

If property is set to 1, the PHY shall advertise a request
to operate the 10BASE-T1L PHY in increased transmit level mode.
If property is set to zero, the PHY shall not advertise
a request to operate the 10BASE-T1L PHY in increased transmit level mode.

4fdabd509d dt-bindings: net: lan966x: remove PHY reset
The PHY reset was intended to be a phandle for a special PHY reset
driver for the integrated PHYs as well as any external PHYs. It turns
out, that the culprit is how the reset of the switch device is done.
In particular, the switch reset also affects other subsystems like
the GPIO and the SGPIO block and it happens to be the case that the
reset lines of the external PHYs are connected to a common GPIO line.
Thus as soon as the switch issues a reset during probe time, all the
external PHYs will go into reset because all the GPIO lines will
switch to input and the pull-down on that signal will take effect.

So even if there was a special PHY reset driver, it (1) won't fix
the root cause of the problem and (2) it won't fix all the other
consumers of GPIO lines which will also be reset.

It turns out, the Ocelot SoC has the same weird behavior (or the
lack of a dedicated switch reset) and there the problem is already
solved and all the bits and pieces are already there and this PHY
reset property isn't not needed at all.

There are no users of this binding. Just remove it.
