"lnk" is used as "port0", and it will be used to get "port1" by
of_get_next_child(ports, lnk). It will call of_node_put() inside. This
function is calling of_node_get() to make up for it, but it doesn't call
paired of_node_put(port0) when it quit function.
This of_node_get() itself is not needed, let's remove it.

Before ORing the new clock rate with the control register value read
from the hardware, the existing clock rate needs to be masked off as
otherwise the existing value will interfere with the new one.

The third, and most likely the last, "new features" pull request for
v6.10 with changes both in stack and in drivers. In ath12k and rtw89
we disabled Wireless Extensions just like with iwlwifi earlier. Wi-Fi
7 devices will not support Wireless Extensions (WEXT) anymore so if
someone is still using the legacy WEXT interface it's time to switch
to nl80211 now!
We merged wireless into wireless-next as we decided not to send a
wireless pull request to v6.9 this late in the cycle. Also an
immutable branch with MHI subsystem was merged to get ath11k and
ath12k hibernation working.

netdevsim: add NAPI support
Add NAPI support to netdevsim and register its Rx queues with NAPI
instances. Then add a selftest using the new netdev Python selftest
infra to exercise the existing Netdev Netlink API, specifically the
queue-get API.
This expands test coverage and further fleshes out netdevsim as a test
device. It's still my goal to make it useful for testing things like
flow steering and ZC Rx.

Run tools/testing/selftest/net/csum.c as part of drv-net.
This binary covers multiple scenarios, based on arguments given,
for both IPv4 and IPv6:
- Accept UDP correct checksum
- Detect UDP invalid checksum
- Accept TCP correct checksum
- Detect TCP invalid checksum
- Transmit UDP: basic checksum offload
- Transmit UDP: zero checksum conversion
The test direction is reversed between receive and transmit tests, so
that the NIC under test is always the local machine.
In total this adds up to 12 testcases, with more to follow. For
conciseness, I replaced individual functions with a function factory.
Also detect hardware offload feature availability using Ethtool
netlink and skip tests when either feature is off. This need may be
common for offload feature tests and eventually deserving of a thin
wrapper in lib.py.
Missing are the PF_PACKET based send tests ('-P'). These use
virtio_net_hdr to program hardware checksum offload. Which requires
looking up the local MAC address and (harder) the MAC of the next hop.
I'll have to give it some though how to do that robustly and where
that code would belong.

Up till now the code to start HSR announce timer, which triggers sending
supervisory frames, was assuming that hsr_netdev_notify() would be called
at least twice for hsrX interface. This was required to have different
values for old and current values of network device's operstate.
This is problematic for a case where hsrX interface is already in the
operational state when hsr_netdev_notify() is called, so timer is not
configured to trigger and as a result the hsrX is not sending supervisory
frames to HSR ring.
This error has been discovered when hsr_ping.sh script was run. To be
more specific - for the hsr1 and hsr2 the hsr_netdev_notify() was
called at least twice with different IF_OPER_{LOWERDOWN|DOWN|UP} states
assigned in hsr_check_carrier_and_operstate(hsr). As a result there was
no issue with sending supervisory frames.
However, with hsr3, the notify function was called only once with
operstate set to IF_OPER_UP and timer responsible for triggering
supervisory frames was not fired.
The solution is to use netif_oper_up() and netif_running() helper
functions to assess if network hsrX device is up.
Only then, when the timer is not already pending, it is started.
Otherwise it is deactivated.

Several clocks as well as both sgmiisys phandles were added by mistake
to the Ethernet bindings for MT7988. Also, the total number of clocks
didn't match with the actual number of items listed.
This happened because the vendor driver which served as a reference uses
a high number of syscon phandles to access various parts of the SoC
which wasn't acceptable upstream. Hence several parts which have never
previously been supported (such SerDes PHY and USXGMII PCS) are going to
be implemented by separate drivers. As a result the device tree will
look much more sane.
Quickly align the bindings with the upcoming reality of the drivers
actually adding support for the remaining Ethernet-related features of
the MT7988 SoC.

While moving all the reset code in the PolarFire SoC clock driver to the
reset subsystem, I removed an `#if IS_ENABLED(RESET_CONTROLLER)` from
the driver and moved it to the header, however this was not the correct
thing to do. In the driver such a condition over-eagerly provided a
complete implementation for mpfs_reset_{read,write}() when the reset
subsystem was enabled without the PolarFire SoC reset driver, but in the
header it meant that when the subsystem was enabled and the driver was
not, no implementation for mpfs_reset_controller_register() was
provided. Fix the condition so that the stub implementation of
mpfs_reset_controller_register() is used when the reset driver is
disabled.

Support in RCG and RCG2 are added for supporting setups where the same
frequency can be reached through multiple configurations. This is then
used to rework the IPQ8074 NSS port 5 and 6 clocks to resolve issues
with certain frequencies.
The APSS IPQ5018 PLL type is corrected, to resolve an issue with some
boards failing to boot. The configuration is further corrected, to
reduce the max CPU frequency to its expected value. This comes with a
few more cleanups and corrections for Stromer PLLs.
Kconfig dependencies are corrected for SM8650 GPU and SC8280XP camera
clock controllers.
The MSM8998 Venus clocks are corrected, to make Venus functional.
Downstream remnants related to DisplayPort are cleaned up across SM8450,
SM6350, SM8550, and SM8650.
The MSM8996 CBF PLL is cleaned up by reusing the Huayra APSS register
map.
The seemingly generic configuration of HFPLL is replaced by adding a
QCS404-specific compatible.
On SM8150 the CPUSS AHB clock source clock is removed, as this is not
controlled by Linux.
An unused field is removed in the RPM clock controller context. Missing
MODULE_DEVICE_TABLE is added to MSM8917 and MSM8953 global clock
controller drivers.

btree_iter is used in two ways: either allocated on the stack with a
fixed size MAX_BSETS, or from a mempool with a dynamic size based on the
specific cache set. Previously, the struct had a fixed-length array of
size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized
iterators, which causes UBSAN to complain.
This patch uses the same approach as in bcachefs's sort_iter and splits
the iterator into a btree_iter with a flexible array member and a
btree_iter_stack which embeds a btree_iter as well as a fixed-length
data array.

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_max() is inclusive. So a -1 has been added when needed.

Add Zstandard compression as the 4th supported algorithm since it
becomes more popular now and some end users have asked this for
quite a while [1][2].
Each EROFS physical cluster contains only one valid standard
Zstandard frame as described in [3] so that decompression can be
performed on a per-pcluster basis independently.
Currently, it just leverages multi-call stream decompression APIs with
internal sliding window buffers. One-shot or bufferless decompression
could be implemented later for even better performance if needed.

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...two types of warnings occur:
warning: absolute value function 'abs' given an argument of type
'long' but has parameter of type 'int' which may cause truncation of
value
warning: taking the absolute value of unsigned type 'unsigned long'
has no effect
Fix these by:
a) using labs() in place of abs(), when long integers are involved, and
b) Change to use signed integer data types, in places where subtraction
is used (and could end up with negative values).
c) Remove a duplicate abs() call in cmt_test.c.

[Changes from V1:
- Use a default branch in the switch statement to initialize `val'.]
GCC warns that `val' may be used uninitialized in the
BPF_CRE_READ_BITFIELD macro, defined in bpf_core_read.h as:
[...]
unsigned long long val; \
[...] \
switch (__CORE_RELO(s, field, BYTE_SIZE)) { \
case 1: val = *(const unsigned char *)p; break; \
case 2: val = *(const unsigned short *)p; break; \
case 4: val = *(const unsigned int *)p; break; \
case 8: val = *(const unsigned long long *)p; break; \
} \
[...]
val; \
} \
This patch adds a default entry in the switch statement that sets
`val' to zero in order to avoid the warning, and random values to be
used in case __builtin_preserve_field_info returns unexpected values
for BPF_FIELD_BYTE_SIZE.
Tested in bpf-next master.
No regressions.

Move BCACHEFS_STATFS_MAGIC value to UAPI <linux/magic.h> under
BCACHEFS_SUPER_MAGIC definition (use common approach for name) and reuse the
definition in bcachefs_format.h BCACHEFS_STATFS_MAGIC.
There are other bcachefs magic definitions: BCACHE_MAGIC, BCHFS_MAGIC,
which use UUID_INIT() and are used only in libbcachefs. Therefore move
only BCACHEFS_STATFS_MAGIC value, which can be used outside of
libbcachefs for f_type field in struct statfs in statfs() or fstatfs().
