The IPA interrupt can fire if there is data to be delivered to a GSI
channel that is suspended. This condition occurs in three scenarios.
First, runtime power management automatically suspends the IPA
hardware after half a second of inactivity. This has nothing
to do with system suspend, so a SYSTEM IPA power flag is used to
avoid calling pm_wakeup_dev_event() when runtime suspended.
Second, if the system is suspended, the receipt of an IPA interrupt
should trigger a system resume. Configuring the IPA interrupt for
wakeup accomplishes this.
Finally, if system suspend is underway and the IPA interrupt fires,
we currently call pm_wakeup_dev_event() to abort the system suspend.
The IPA driver correctly handles quiescing the hardware before
suspending it, so there's really no need to abort a suspend in
progress in the third case. We can simply quiesce and suspend
things, and be done.
Incoming data can still wake the system after it's suspended.
The IPA interrupt has wakeup mode enabled, so if it fires *after*
we've suspended, it will trigger a wakeup (if not disabled via
sysfs).
Stop calling pm_wakeup_dev_event() to abort a system suspend in
progress in ipa_power_suspend_handler().

====================
mptcp: various small improvements
This series brings various small improvements to MPTCP and its
selftests:
Patch 1 prints an error if there are duplicated subtests names. It is
important to have unique (sub)tests names in TAP, because some CI
environments drop (sub)tests with duplicated names.
Patch 2 is a preparation for patches 3 and 4, which check the protocol
in tcp_sk() and mptcp_sk() with DEBUG_NET, only in code from net/mptcp/.
We recently had the case where an MPTCP socket was wrongly treated as a
TCP one, and fuzzers and static checkers never spot the issue. This
would prevent such issues in the future.
Patches 5 to 7 are some cleanup for the MPTCP selftests. These patches
are not supposed to change the behaviour.
Patch 8 sets the poll timeout in diag selftest to the same value as the
one used in the other selftests.

df62f2ec3df6 ("selftests/mptcp: add diag interface tests"), there is
no reason not to have it to 30ms like all the other tests. "diag.sh" is

Fuzzers and static checkers might not detect when mptcp_sk() is used
with a non mptcp_sock structure.
This is similar to the parent commit, where it is easy to use mptcp_sk()
with a TCP sock, e.g. with a subflow sk.
So a new simple check is done when CONFIG_DEBUG_NET is enabled to tell
kernel devs when a non-MPTCP socket is being used as an MPTCP one.
'mptcp_sk()' macro is then defined differently: with an extra WARN to
complain when an unexpected socket is being used.

Fuzzers and static checkers might not detect when tcp_sk() is used with
a non tcp_sock structure.
This kind of mistake already happened a few times with MPTCP: when
wrongly using TCP-specific helpers with mptcp_sock pointers. On the
other hand, there are many 'tcp_xxx()' helpers that are taking a 'struct
sock' pointer as arguments, and some of them are only looking at fields
from 'struct sock', and nothing from 'struct tcp_sock'. It is then
tempting to use them with a 'struct mptcp_sock'.
So a new simple check is done when CONFIG_DEBUG_NET is enabled to tell
kernel devs when a non-TCP socket is being used as a TCP one. 'tcp_sk()'
macro is then re-defined to add a WARN when an unexpected socket is
being used.

It is important to have a unique (sub)test name in TAP, because some CI
environments drop tests with duplicated name.
When adding a new subtest entry, an error message is printed in case of
duplicated entries. If there were duplicated entries and if all features
were expected to work, the script exits with an error at the end, after
having printed all subtests in the TAP format. Thanks to that, the MPTCP
CI will catch such issues early.

net: pcs: xpcs: Cleanups before adding MMIO dev support
As stated in the subject this series is a short prequel before submitting
the main patches adding the memory-mapped DW XPCS support to the DW XPCS
and DW *MAC (STMMAC) drivers. Originally it was a part of the bigger
patchset (see the changelog v2 link below) but was detached to a
preparation set to shrink down the main series thus simplifying it'
review.
The patchset' content is straightforward: drop the redundant sentinel
entry and the header files; return EINVAL errno from the soft-reset method
and make sure that the interface validation method return EINVAL straight
away if the requested interface isn't supported by the XPCS device
instance. All of these changes are required to simplify the changes being
introduced a bit later in the framework of the memory-mapped DW XPCS
support patches.

If an unsupported interface is passed to the PCS validation callback there
is no need in further link-modes calculations since the resultant array
will be initialized with zeros which will be perceived by the phylink
subsystem as error anyway (see phylink_validate_mac_and_pcs()). Instead
let's explicitly return the -EINVAL error to inform the caller about the
unsupported interface as it's done in the rest of the pcs_validate
callbacks.

In particular the xpcs_soft_reset() and xpcs_do_config() functions
currently return -1 if invalid auto-negotiation mode is specified. That
value might be then passed to the generic kernel subsystems which require
a standard kernel errno value. Even though the erroneous conditions are
very specific (memory corruption or buggy driver implementation) using a
hard-coded -1 literal doesn't seem correct anyway especially when it comes
to passing it higher to the network subsystem or printing to the system
log. Convert the hard-coded error values to -EINVAL then.

There are currently only two methods (xpcs_find_compat() and
xpcs_get_interfaces()) defined in the driver which loop over the available
interfaces. All of them rely on the xpcs_compat::num_interfaces field
value to get the total number of supported interfaces. Thus the interface
arrays are supposed to be filled with actual interface IDs and there is no
need in the dummy terminating ID placed at the end of the arrays.
Based on the above drop the PHY_INTERFACE_MODE_MAX entry from the
xpcs_2500basex_interfaces array and the PHY_INTERFACE_MODE_MAX-based
conditional statement from the xpcs_get_interfaces() method as redundant.

This series restarts the conversion of rtnl dump operations

Add support for TI DP83826 configuration
This short patch series introduces the possibility of overriding
some parameters which are latched by default by hardware straps on the
TI DP83826 PHY.
The settings that can be overridden include:
- Configuring the PHY in either MII mode or RMII mode.
- When in RMII mode, configuring the PHY in RMII slave mode or RMII
master mode.
The RMII master/slave mode is TI-specific and determines whether the PHY
operates from a 25MHz reference clock (master mode) or from a 50MHz
reference clock (slave mode).
While these features should be supported by all the TI DP8382x family,
I have only been able to test them on TI DP83826 hardware. Therefore,
support has been added specifically for this PHY in this patch series.

However, when user constructs json message, he has to pass plain scalar
values. See "state" "selector" and "value" attributes in following
examples:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml --do pin-set --json '{"id": 0, "parent-device": {"parent-id": 0, "state": 1}}'
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml --do port-set --json '{"bus-name": "pci", "dev-name": "0000:08:00.1", "port-index": 98304, "port-function": {"caps": {"selector": 1, "value": 1 }}}'
Allow user to pass strings containing enum names, convert them to scalar
values to be encoded into Netlink message:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml --do pin-set --json '{"id": 0, "parent-device": {"parent-id": 0, "state": "connected"}}'
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml --do port-set --json '{"bus-name": "pci", "dev-name": "0000:08:00.1", "port-index": 98304, "port-function": {"caps": {"selector": ["roce-bit"], "value": ["roce-bit"] }}}'

As a preparation to handle enums for scalar values, unify the processing
of all scalar types in a single elif statement.

The flag attr presence in Netlink message indicates value "true",
if it is missing in the message it means "false".
Allow user to specify attrname with value "true"/"false"
in json for flag attrs, treat "false" value properly.

John Garry says:
====================
net: Don't bother filling in ethtool driver version
The drivers included in this series set the ethtool driver version to the
same as the default, UTS_RELEASE, so don't both doing this.
As noted by Masahiro in [0], with CONFIG_MODVERSIONS=y, some drivers could
be built as modules against a different kernel tree with differing
UTS_RELEASE. As such, these changes could lead to a change in behaviour.
However, defaulting to the core kernel UTS_RELEASE would be expected
behaviour.

* Update the Kernel Doc for gelic_descr_set_tx_cmdstat()
and gelic_net_setup_netdev() so that documented name
and the actual name of the function match.
* Move define of GELIC_ALIGN() so that it is no longer
between gelic_alloc_card_net() and it's Kernel Doc.
* Document netdev parameter of gelic_alloc_card_net()
in a way consistent to the documentation of other netdev parameters
in this file.
Addresses the following warnings flagged by ./scripts/kernel-doc -none:
.../ps3_gelic_net.c:711: warning: expecting prototype for gelic_net_set_txdescr_cmdstat(). Prototype was for gelic_descr_set_tx_cmdstat() instead
