In PCI and HAL interface layer module, the identifier sc is used
to represent an instance of ath12k_base structure. However,
within ath12k, the convention is to use "ab" to represent an SoC
"base" struct. So change the all instances of sc to ab.

Firmware IE containers can dynamically provide various information
what firmware supports. Also it can embed more than one image so
updating firmware is easy, user just needs to update one file in
/lib/firmware/.
The firmware API 2 or higher will use the IE container format, the
current API 1 will not use the new format but it still is supported
for some time. Firmware API 2 files are named as firmware-2.bin
(which contains both amss.bin and m3.bin images) and API 1 files are
amss.bin and m3.bin.
Currently ath11k PCI driver provides firmware binary (amss.bin) path to
MHI driver, MHI driver reads firmware from filesystem and boots it. Add
provision to read firmware files from ath11k driver and provide the amss.bin
firmware data and size to MHI using a pointer.
Currently enum ath11k_fw_features is empty, the patches adding features will
add the flags.
With AHB devices there's no amss.bin or m3.bin, so no changes in how AHB
firmware files are used. But AHB devices can use future additions to the meta
data, for example in enum ath11k_fw_features.

Simple refactoring to make it easier to add firmware-2.bin support in the
following patch.
Earlier ath11k_qmi_m3_load() supported changing m3.bin contents while ath11k is
running. But that's not going to actually work, m3.bin is supposed to be the
same during the lifetime of ath11k, for example we don't support changing the
firmware capabilities on the fly. Due to this ath11k requests m3.bin firmware
file first and only then checks m3_mem->vaddr, so we are basically requesting
the firmware file even if it's not needed. Reverse the code so that m3_mem
buffer is checked first, and only if it doesn't exist, then m3.bin is requested
from user space.
Checking for m3_mem->size is redundant when m3_mem->vaddr is NULL, we would
not be able to use the buffer in that case. So remove the check for size.
Simplify the exit handling and use 'goto out'.

Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via
file private data"), the miscdevice stores a pointer to itself inside
filp->private_data, which means that private_data will not be NULL when
wmi_char_open() is called. This might cause memory corruption should
wmi_char_open() be unable to find its driver, something which can
happen when the associated WMI device is deleted in wmi_free_devices().
Fix the problem by using the miscdevice pointer to retrieve the WMI
device data associated with a char device using container_of(). This
also avoids wmi_char_open() picking a wrong WMI device bound to a
driver with the same name as the original driver.

When a WMI device besides the first one somehow fails to register,
retval is returned while still containing a negative error code. This
causes the ACPI device fail to probe, leaving behind zombie WMI devices
leading to various errors later.
Handle the single error path separately and return 0 unconditionally
after trying to register all WMI devices to solve the issue. Also
continue to register WMI devices even if some fail to allocate memory.

Until now, legacy GUID-based functions where using find_guid() when
searching for WMI devices, which did no refcounting on the returned
WMI device. This meant that the WMI device could disappear at any
moment, potentially leading to various errors. Fix this by using
bus_find_device() which returns an actual reference to the found
WMI device.

Many aggregate WMI drivers do not use -EPROBE_DEFER when they
cannot find a WMI device during probe, instead they require
all WMI devices associated with an platform device to become
available at once. This is currently achieved by adding those
WMI devices to the wmi_block_list before they are registered,
which is then used by the deprecated GUID-based functions to
search for WMI devices.
Replace this approach with a device link which defers probing
of the WMI device until the associated platform device has finished
probing (and has registered all WMI devices). New aggregate WMI
drivers should not rely on this behaviour.

Current nf_flow_is_outdated() implementation considers any flow table flow
which state diverged from its underlying CT connection status for teardown
which can be problematic in the following cases:
- Flow has never been offloaded to hardware in the first place either
because flow table has hardware offload disabled (flag
NF_FLOWTABLE_HW_OFFLOAD is not set) or because it is still pending on 'add'
workqueue to be offloaded for the first time. The former is incorrect, the
later generates excessive deletions and additions of flows.
- Flow is already pending to be updated on the workqueue. Tearing down such
flows will also generate excessive removals from the flow table, especially
on highly loaded system where the latency to re-offload a flow via 'add'
workqueue can be quite high.
When considering a flow for teardown as outdated verify that it is both
offloaded to hardware and doesn't have any pending updates.

Since 41f2c7c342d3 ("net/sched: act_ct: Fix promotion of offloaded
unreplied tuple"), flowtable GC pushes back flows with IPS_SEEN_REPLY
back to classic path in every run, ie. every second. This is because of
a new check for NF_FLOW_HW_ESTABLISHED which is specific of sched/act_ct.
In Netfilter's flowtable case, NF_FLOW_HW_ESTABLISHED never gets set on
and IPS_SEEN_REPLY is unreliable since users decide when to offload the
flow before, such bit might be set on at a later stage.
Fix it by adding a custom .gc handler that sched/act_ct can use to
deal with its NF_FLOW_HW_ESTABLISHED bit.

reported by acpi_video
For a long time now the acpi_video driver reports evdev brightness up/down
key events for the brightness hotkeys on most (non ancient) laptops.
asus-wmi also reports evdev brightness up/down key events for these
keys leading to each press being reported twice and e.g. GNOME increasing
the brightness by 2 steps instead of 1 step.
Use the acpi_video_handles_brightness_key_presses() helper to detect if
acpi_video is reporting brightness key-presses and if it is then don't
report the same events also from the asus-wmi driver.
Note there is a chance that this may lead to regressions where
the brightness hotkeys stop working because they are not actually
reported by the acpi_video driver. Unfortunately the only way to
find out if this is a problem is to try.
To at least avoid regressions on old hw using the eeepc-wmi driver,
implement this as a key filter in asus-nb-wmi so that the eeepc-wmi
driver is not affected.

====================
Create a binding for the Marvell MV88E6xxx DSA switches
The Marvell switches are lacking DT bindings.
I need proper schema checking to add LED support to the
Marvell switch. Just how it is, it can't go on like this.
Some Device Tree fixes are included in the series, these
remove the major and most annoying warnings fallout noise:
some warnings remain, and these are of more serious nature,
such as missing phy-mode. They can be applied individually,
or to the networking tree with the rest of the patches.

The Marvell MV88E6060 is one of the oldest DSA switches from
Marvell, and it has DT bindings used in the wild. Let's define
them properly.
It is different enough from the rest of the MV88E6xxx switches

When the MSM8909 SoC is used together with the PM8909 PMIC the primary
power supply for the CPU (VDD_APC) is shared with other components to
the SoC, namely the VDD_CX power domain typically supplied by the PM8909
S1 regulator. This means that all votes for necessary performance states
go via the RPM firmware which collects the requirements from all the
processors in the SoC. The RPM firmware then chooses the actual voltage
based on the performance states ("corners"), depending on calibration
values in the NVMEM and other factors.
The MSM8909 SoC is also sometimes used with the PM8916 or PM660 PMIC.
In that case there is a dedicated regulator connected to VDD_APC and
Linux is responsible to do adaptive voltage scaling using CPR (similar
to the existing code for QCS404).
This difference can be described in the device tree, by either assigning
the CPU a power domain from RPMPD or from the CPR driver.
Describe this using "perf" as generic power domain name, which is also
used already for SCMI based platforms.
Also add a simple function that reads the speedbin from a NVMEM cell
and sets it as-is for opp-supported-hw. The actual bit position can be
described in the device tree without additional driver changes.

2. For external PA/LNA devices, restore RF and BBP registers before
R-Calibration.
3. Do Rx DCOC calibration again before RXIQ calibration.
4. Add some missing LNA related registers' initialization.

1. Move the channel configuration code from rt2800_vco_calibration()
to the rt2800_config_channel().
2. Use MT7620 SoC specific AGC initial LNA value instead of the
RT5592's value.
3. BBP{195,196} pairing write has been replaced with
rt2800_bbp_glrt_write() to reduce redundant code.

1. Do not hard reset the BBP. We can use soft reset instead. This
change has some help to the calibration failure issue.
2. Enable falling back to legacy rate from the HT/RTS rate by
setting the HT_FBK_TO_LEGACY register.
3. Implement MCS rate specific maximum PSDU size. It can improve
the transmission quality under the low RSSI condition.
4. Set BBP_84 register value to 0x19. This is used for extension
channel overlapping IOT.

This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.
To prevent the potential deadlock, the patch use spin_lock_irqsave()
on &dd->irq_src_lock inside read_mod_write() to prevent the possible
deadlock scenario.

Add WoL support for KSZ9477 family of switches. This code was tested on
KSZ8563 chip.
KSZ9477 family of switches supports multiple PHY events:
- wake on Link Up
- wake on Energy Detect.
Since current UAPI can't differentiate between this PHY events, map all
of them to WAKE_PHY.

KSZ switches with WoL support signals wake event over PME pin. If this
pin is attached to some external PMIC or System Controller can't be
described as GPIO, the only way to describe it in the devicetree is to
use wakeup-source property. So, add support for this property and enable
PME switch output if this property is present.

With commit 9fee28baa601 ("powerpc: implement the new page table range
API") we added set_ptes to powerpc architecture. The implementation
included calling arch_enter/leave_lazy_mmu() calls.
The patch removes the usage of arch_enter/leave_lazy_mmu() because
set_pte is not supposed to be used when updating a pte entry. Powerpc
architecture uses this rule to skip the expensive tlb invalidate which
is not needed when you are setting up the pte for the first time. See
commit 56eecdb912b5 ("mm: Use ptep/pmdp_set_numa() for updating
_PAGE_NUMA bit") for more details
The patch also makes sure we are not using the interface to update a
valid/present pte entry by adding VM_WARN_ON check all the ptes we
are setting up. Furthermore, we add a comment to set_pte_filter to
clarify it can only update folio-related flags and cannot filter
pfn specific details in pte filtering.
Removal of arch_enter/leave_lazy_mmu() also will avoid nesting of
these functions that are not supported. For ex:
remap_pte_range()
-> arch_enter_lazy_mmu()
-> set_ptes()
-> arch_enter_lazy_mmu()
-> arch_leave_lazy_mmu()
-> arch_leave_lazy_mmu()

utf16s_to_utf8s does not NULL terminate the output string. For us to be
able to add a NULL character when utf16s_to_utf8s returns, we need to make
sure that there is space for such NULL character at the end of the output
buffer. We can achieve this by passing an output buffer size to
utf16s_to_utf8s that is one character less than what we allocated.
Other call sites of utf16s_to_utf8s appear to be using the same technique
where they artificially reduce the buffer size by one to leave space for a
NULL character or line feed character.
