The driver needs to handle GPIO interrupts to identify SFP module and
configure PHY by sending mailbox messages to firmware.
Since the SFP module needs to wait for ready to get information when it
is inserted, workqueue is added to handle delayed tasks. And each SW-FW
interaction takes time to wait, so they are processed in the workqueue
instead of IRQ handler function.

There is a new PHY attached to AML 25G/10G NIC, which is different from

Most of the different code that requires MAC type in the common library
is due to NGBE only supports a few queues and pools, unlike TXGBE, which
supports 128 queues and 64 pools. This difference accounts for most of
the hardware configuration differences in the driver code. So add a flag
bit "WX_FLAG_MULTI_64_FUNC" for them to clean-up the driver code.

The KSZ9477 switch driver uses the XPCS driver to operate its SGMII
port. However there are some hardware bugs in the KSZ9477 SGMII
module so workarounds are needed. There was a proposal to update the
XPCS driver to accommodate KSZ9477, but the new code is not generic
enough to be used by other vendors. It is better to do all these
workarounds inside the KSZ9477 driver instead of modifying the XPCS
driver.
There are 3 hardware issues. The first is the MII_ADVERTISE register
needs to be write once after reset for the correct code word to be
sent. The XPCS driver disables auto-negotiation first before
configuring the SGMII/1000BASE-X mode and then enables it back. The
KSZ9477 driver then writes the MII_ADVERTISE register before enabling
auto-negotiation. In 1000BASE-X mode the MII_ADVERTISE register will
be set, so KSZ9477 driver does not need to write it.
The second issue is the MII_BMCR register needs to set the exact speed
and duplex mode when running in SGMII mode. During link polling the
KSZ9477 will check the speed and duplex mode are different from
previous ones and update the MII_BMCR register accordingly.
The last issue is 1000BASE-X mode does not work with auto-negotiation
on. The cause is the local port hardware does not know the link is up
and so network traffic is not forwarded. The workaround is to write 2
additional bits when 1000BASE-X mode is configured.
Note the SGMII interrupt in the port cannot be masked. As that
interrupt is not handled in the KSZ9477 driver the SGMII interrupt bit
will not be set even when the XPCS driver sets it.

Pull vfs directory lookup updates from Christian Brauner:
"This contains cleanups for the lookup_one*() family of helpers.
We expose a set of functions with names containing "lookup_one_len"
and others without the "_len". This difference has nothing to do with
"len". It's rater a historical accident that can be confusing.
The functions without "_len" take a "mnt_idmap" pointer. This is found
in the "vfsmount" and that is an important question when choosing
which to use: do you have a vfsmount, or are you "inside" the
filesystem. A related question is "is permission checking relevant
here?".
nfsd and cachefiles *do* have a vfsmount but *don't* use the non-_len
functions. They pass nop_mnt_idmap and refuse to work on filesystems
which have any other idmap.
This work changes nfsd and cachefile to use the lookup_one family of
functions and to explictily pass &nop_mnt_idmap which is consistent
with all other vfs interfaces used where &nop_mnt_idmap is explicitly
passed.
The remaining uses of the "_one" functions do not require permission
checks so these are renamed to be "_noperm" and the permission
checking is removed.
This series also changes these lookup function to take a qstr instead
of separate name and len. In many cases this simplifies the call"

Syzkaller, courtesy of syzbot, identified an error (see report [1]) in
aqc111 driver, caused by incomplete sanitation of usb read calls'
results. This problem is quite similar to the one fixed in commit
920a9fa27e78 ("net: asix: add proper error handling of usb read errors").
For instance, usbnet_read_cmd() may read fewer than 'size' bytes,
even if the caller expected the full amount, and aqc111_read_cmd()
will not check its result properly. As [1] shows, this may lead
to MAC address in aqc111_bind() being only partly initialized,
triggering KMSAN warnings.
Fix the issue by verifying that the number of bytes read is
as expected and not less.

Adjust the enabling/disabling steps of the DP audio SDP splitting
according to a recent Bspec update. This moves the enabling to the audio
codec enable sequence after the transcoder is enabled and disables SDP
splitting explicitly during the audio disable sequence.
Bspec requires waiting for a vblank event after the transcoder is
enabled and before SDP splitting is enabled. There is no need for an
explicit wait for this, since after the transcoder is enabled this
vblank event is guaranteed to have happened via a flip done wait (see
intel_atomic_commit_tail() -> drm_atomic_helper_wait_for_flip_done()).
The bspec update is for LNL+ only, but the HW team clarified that this
has been always the intended sequence on all platforms and bspec will be
updated everywhere accordingly.
The way SDP splitting was originally enabled matched the version of
bspec at that time. Adding here the Fixes: line still, since this
change fixes a FIFO underrun on PTL during output enabling when DSC is
enabled.

Signal vt subsystem to redraw console when switching to dummycon
with deferred takeover enabled. Makes the console switch to fbcon
and displays the available output.
With deferred takeover enabled, dummycon acts as the placeholder
until the first output to the console happens. At that point, fbcon
takes over. If the output happens while dummycon is not active, it
cannot inform fbcon. This is the case if the vt subsystem runs in
graphics mode.
A typical graphical boot starts plymouth, a display manager and a
compositor; all while leaving out dummycon. Switching to a text-mode
console leaves the console with dummycon even if a getty terminal
has been started.
Returning true from dummycon's con_switch helper signals the vt
subsystem to redraw the screen. If there's output available dummycon's
con_putc{s} helpers trigger deferred takeover of fbcon, which sets a
display mode and displays the output. If no output is available,
dummycon remains active.

The driver currently uses dev_err for messages that have a very low probability
of being read by the user as the error will probably never happen and the
systems with the RTC probably don't have any user able to read the message.
Moreover, the only user action after getting this message is the restart the
action so drop the level to dev_dbg.

RTC tracks clock time during system suspend. It can be a wakeup source
for the S32G2/S32G3 SoC based boards.
The RTC module from S32G2/S32G3 is not battery-powered and it is not kept
alive during system reset.

As it's name suggests, parse_eeprom() parses EEPROM data.
This is done by reading data, 16 bits at a time as follows:
for (i = 0; i < 128; i++)
((__le16 *) sromdata)[i] = cpu_to_le16(read_eeprom(np, i));
sromdata is at the same memory location as psrom.
And the type of psrom is a pointer to struct t_SROM.
As can be seen in the loop above, data is stored in sromdata, and thus
psrom, as 16-bit little-endian values. However, the integer fields of
t_SROM are host byte order.
In the case of the led_mode field this results in a but which has been
addressed by commit e7e5ae71831c ("net: dlink: Correct endianness
handling of led_mode").
In the case of the remaining fields, which are updated by this patch,
I do not believe this does not result in any bugs. But it does seem
best to correctly annotate the endianness of integers.

The AF driver assigns reserved MCAM entries (for unicast, broadcast,
etc.) based on the NIXLF number. When a NIXLF is detached, these entries
are disabled.
For example,
PF NIXLF
--------------------
PF0 0
SDP-VF0 1
If the user unbinds both PF0 and SDP-VF0 interfaces and then binds them in
reverse order
PF NIXLF
---------------------
SDP-VF0 0
PF0 1
In this scenario, the PF0 unicast entry is getting corrupted because
the MCAM entry contains stale data (SDP-VF0 ucast data)
This patch resolves the issue by clearing the unicast MCAM entry during
NIXLF detach

When an application sets and enables an alarm on Loongson RTC devices,
the alarm notification fails to propagate to userspace because the
ACPI event handler omits calling rtc_update_irq().
As a result, processes waiting via select() or poll() on RTC device
files fail to receive alarm notifications.
The ACPI interrupt is also triggered multiple times. In loongson_rtc_handler,
we need to clear TOY_MATCH0_REG to resolve this issue.
