====================
dt-bindings: net: qcom,ipa: relax some restrictions
The first patch in this series simply removes an unnecessary
requirement in the IPA binding. Previously, if the modem was doing
GSI firmware loading, the firmware name property was required to
*not* be present. There is no harm in having the firmware name be
specified, so this restriction isn't needed.
The second patch restates a requirement on the "memory-region"
property more accurately.
These binding changes have no impact on existing code or DTS files.
These aren't really bug fixes, so no need to back-port.

Either the AP or modem loads GSI firmware. If the modem-init
property is present, the modem loads it. Otherwise, the AP loads
it, and in that case the memory-region property must be defined.
Currently this requirement is expressed as one or the other of the
modem-init or the memory-region property being required. But it's
harmless for the memory-region to be present if the modem is loading
firmware (it'll just be ignored).
Restate the requirement so that the memory-region property is
required only if modem-init is not present.

If the AP loads GSI firmware, the name of the firmware file to use

separate change.
The remaining drivers, bnx2x, liquidio, cxgb4, fec, and qede implement
.adjfreq in a way different from the normal pattern expected by
adjust_by_scaled_ppm. Fixing these drivers to properly use .adjfine requires
specific knowledge of the hardware implementation. Instead I simply refactor
them to use .adjfine and convert scaled_ppm into ppb using the
scaled_ppm_to_ppb function.
Finally, the .adjfreq implementation interface is removed entirely. This
simplifies the interface and ensures that new drivers must implement the new
interface as they no longer have an alternative.
This still leaves parts per billion used as part of the max_adj interface,
and the core PTP stack still converts scaled_ppm to ppb to check this. I
plan to investigate fixing this in the future.

Merge branch 'sparx5-TC-key'
Steen Hegelund says:
====================
Extend TC key support for Sparx5 IS2 VCAP
This provides extended tc flower filter key support for the Sparx5 VCAP
functionality.
It builds on top of the initial IS2 VCAP support found in this series:
https://lore.kernel.org/all/
20221020130904.1215072-1-steen.hegelund@microchip.com/
Overview:
=========
The added flower filter key (dissector) support is this:
- ipv4_addr (sip and dip)
- ipv6_addr (sip and dip)
- control (IPv4 fragments)
- portnum (tcp and udp port numbers)
- basic (L3 and L4 protocol)
- vlan (outer vlan tag info)
- tcp (tcp flags)
- ip (tos field)
The IS2 VCAP supports classified VLAN information which amounts to the
outer VLAN info in case of multiple tags.
Functionality:
==============
Before frames can match IS2 VCAP rules with e.g an IPv4 source address, the
IS2 VCAPs keyset configuration must include keyset that contains a IPv4
source address and this must be configured for the lookup/port/traffic-type
that you want to match on.
The Sparx5 IS2 VCAP has the following traffic types:
- Non-Ethernet frames
- IPv4 Unicast frames
- IPv4 Multicast frames
- IPv6 Unicast frames
- IPv6 Multicast frames
- ARP frames
So to cover IPv4 traffic the two IPv4 categories must be configured with a
keyset that contains IPv4 address information such as the
VCAP_KFS_IP4_TCP_UDP keyset.
The IPv4 and IPv6 traffic types are configured with useful default keysets,
in later series we will use the tc template functionality when we want to
change these defaults.
The flower filter must contain a goto action as its last action and the
chain id must specify the chain id of the next lookup in a VCAP or a
destination outside the VCAP ranges.
To activate the VCAP lookups on a port you must add a TC matchall filter on
the port containing a single goto action that points to the chain id of the
first lookup in the IS2 VCAP.
From then on frames arriving on this port will be matched against the
rules in the IS2 VCAP lookups.
Removing the matchall filter will deactivate the IS2 lookups, but will
leave the VCAP rules in the memory of the VCAP instance, and from then in
frames will no longer be matched against the rules the in IS2 VCAP.
If the matchall rule is added back again the IS2 rules will be active
once more.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- TC flower filter statistics and rule order by size and priority
- debugfs support for inspecting rules
- support for TC protocol all
- Sparx5 IS0 VCAP support
- add TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support
Version History:
================
v6 Rebased on the latest next-next master branch.
No other implementation changes.
v5 Add support for a TC matchall filter with a single goto action
which will activate the lookups of the VCAP. Removing this filter
will deactivate the VCAP lookups again.
v4 Add support for TC flower filter goto action and a check of the
actions: check action combinations and the goto chain id.
v3 Add some more details to the explanation in the commit message
about support for MAC_ETYPE keysets and "protocol all" as well as
the classified VLAN information. This is done to help testing the
feature.
No implementation changes in this version.
v2 Split one of the KUNIT tests into 3 tests to fix a kernel robot
build warning.

devlink: Fix warning when unregistering a port
When a devlink port is unregistered, its type is expected to be unset or
otherwise a WARNING is generated [1]. This was supposed to be handled by
cited commit by clearing the type upon 'NETDEV_PRE_UNINIT'.
The assumption was that no other events can be generated for the netdev
after this event, but this proved to be wrong. After the event is
generated, netdev_wait_allrefs_any() will rebroadcast a
'NETDEV_UNREGISTER' until the netdev's reference count drops to 1. This
causes devlink to set the port type back to Ethernet.
Fix by only setting and clearing the port type upon 'NETDEV_POST_INIT'
and 'NETDEV_PRE_UNINIT', respectively. For all other events, preserve
the port type.

If ethtool_ops::get_drvinfo() callback isn't set,
ethtool_get_drvinfo() will fill the ethtool_drvinfo::name and
ethtool_drvinfo::bus_info fields.
However, if the driver provides the callback function, those two
fields are not touched. This means that the driver has to fill these
itself.
Allow the driver to leave those two fields empty and populate them in
such case. This way, the driver can rely on the default values for the

Merge tag 'hwlock-v6.1' of git://git./linux/kernel/git/remoteproc/linux
Pull hwspinlock updates from Bjorn Andersson:
"I apparently had missed tagging and sending this set of changes out
during the 6.1 merge window. But did get the associated dts changes
depending on this merged. The result is a regression in 6.1-rc on the
affected, older, Qualcomm platforms - in for form of them not booting.
So while these weren't regression fixes originally, they are now. It's
not introducing new beahavior, but simply extending the existing new
Devicetree model, to cover remaining platforms:
- extend the DeviceTree binding and implementation for the Qualcomm
hardware spinlock on some older platforms to follow the style of
the newer ones where the DeviceTree representation does not rely on
an intermediate syscon node"

In the scenario where the macvlan mode is configured as 'source',
macvlan_changelink_sources() will be execured to reconfigure list of
remote source mac addresses, at the same time, if register_netdevice()

is not cleaned up.
Using this patch, in the case of an error, it will execute
macvlan_flush_sources() to ensure that the resource is cleaned up.

====================
macsec: clear encryption keys in h/w drivers
Commit
aaab73f8fba4 ("macsec: clear encryption keys from the stack after
setting up offload") made sure to clean encryption keys from the stack
after setting up offloading but some h/w drivers did a copy of the key
which need to be zeroed as well.
The MSCC PHY driver can actually be converted not to copy the encryption
key at all, but such patch would be quite difficult to backport. I'll
send a following up patch doing this in net-next once this series lands.
Tested on the MSCC PHY but not on the atlantic NIC.
