7b789ea390 wifi: ath12k: support OBSS PD configuration for AP mode
Configure HE OBSS PD for spatial reuse in ath12k based on mac80211
HE SPR parameters in AP mode. This adds a pdev-level helper that
programs SRG/non-SRG OBSS PD thresholds, per-AC enablement, SR prohibit
control, and SRG/non-SRG BSS color and partial BSSID bitmaps via WMI.

Replace the previous vdev-level OBSS SPR command usage with the new
pdev-level configuration path, allowing firmware to apply HE spatial
reuse behavior according to the HE SPR/OBSS PD settings provided by
mac80211.

6dbd496a17 wifi: ath12k: add WMI support for spatial reuse parameter configuration
Add WMI support for configuring SRG and non-SRG OBSS PD bitmaps at
the pdev level. The new commands allow the host to set BSS color bitmaps,
partial BSSID bitmaps, and the corresponding enable masks used for
SRG/non-SRG OBSS PD processing.

Introduce new WMI command IDs, TLV tags, a service flag
(WMI_TLV_SERVICE_SRG_SRP_SPATIAL_REUSE_SUPPORT), and a bitmap payload
structure required by these commands. These additions are needed to
support HE Spatial Reuse and firmware-managed OBSS PD behavior.

The APIs introduced in this patch will be utilized in an upcoming patch.

adce4fa499 dt-bindings: net: wireless: ath11k-pci: deprecate 'firmware-name' property
The firmware-name property was originally introduced to allow end-users
and integrators to select use-case-specific firmware for the WCN6855.
However, specifying firmware for an M.2 WLAN module in the Device Tree
is not appropriate. Instead, this functionality will be handled within
the ath11k driver. Therefore, the firmware-name property is now
deprecated.

c386a2b106 wifi: ath11k: add usecase firmware handling based on device compatible
For M.2 WLAN chips, there is no suitable DTS node to specify the
firmware-name property. In addition, assigning firmware for the
M.2 PCIe interface causes chips that do not use usecase specific
firmware to fail. Therefore, abandoning the approach of specifying
firmware in DTS. As an alternative, propose a static lookup table
mapping device compatible to firmware names. Currently, only WCN6855
HW2.1 requires this.

However, support for the firmware-name property is retained to keep
the ABI backwards compatible.

For details on usecase specific firmware, see:
https://lore.kernel.org/all/20250522013444.1301330-3-miaoqing.pan@oss.qualcomm.com/.

e55ac34808 wifi: ath10k: sdio: add missing lock protection in ath10k_sdio_fw_crashed_dump()
ath10k_sdio_fw_crashed_dump() calls ath10k_coredump_new() which requires
ar->dump_mutex to be held, as indicated by lockdep_assert_held() in that
function. However, the SDIO implementation does not acquire this lock,
unlike the PCI and SNOC implementations which properly hold the mutex.

Additionally, ar->stats.fw_crash_counter is documented as protected by
ar->data_lock in core.h, but the SDIO implementation modifies it without
holding this spinlock.

Add the missing mutex_lock()/mutex_unlock() around the coredump
operations, and add spin_lock_bh()/spin_unlock_bh() around the
fw_crash_counter increment, following the pattern used in
ath10k_pci_fw_dump_work() and ath10k_snoc_fw_crashed_dump().

820ba7dd68 wifi: ath10k: fix lock protection in ath10k_wmi_event_peer_sta_ps_state_chg()
ath10k_wmi_event_peer_sta_ps_state_chg() uses lockdep_assert_held() to
assert that ar->data_lock should be held by the caller, but neither
ath10k_wmi_10_2_op_rx() nor ath10k_wmi_10_4_op_rx() acquire this lock

The field arsta->peer_ps_state is documented as protected by
ar->data_lock in core.h, and other accessors (ath10k_peer_ps_state_disable,
ath10k_dbg_sta_read_peer_ps_state) properly acquire this lock.

Add spin_lock_bh()/spin_unlock_bh() around the peer_ps_state update,
and remove the lockdep_assert_held() to be aligned with new locking,
following the pattern used by other WMI event handlers in the driver.

e31fa691d0 wifi: iwlegacy: add missing mutex protection in il4965_store_tx_power()
il4965_store_tx_power() calls il_set_tx_power() without holding il->mutex.
However, il_set_tx_power() has lockdep_assert_held(&il->mutex) indicating
that callers must hold this lock.

All other callers of il_set_tx_power() properly acquire the mutex:
- il_bg_scan_completed() acquires mutex at common.c:1683
- il_mac_config() acquires mutex at common.c:5006
- il3945_commit_rxon() and il4965_commit_rxon() are called via work
  queues that hold the mutex (like il4965_bg_alive_start)

Add mutex_lock()/mutex_unlock() around the il_set_tx_power() call in
the sysfs store function to fix the missing lock protection.

9b50d9c06c wifi: p54: Fix memory leak in p54_beacon_update()
In p54_beacon_update(), beacon is allocated via ieee80211_beacon_get().
If p54_beacon_format_ie_tim() fails, the function returns immediately
without freeing the allocated beacon skb, which would lead to a memory
leak.

Since no other references to this memory exist, it must be freed locally
before returning the error. Fix this by freeing the buffer using
dev_kfree_skb_any() in the error path.

Note that this error path is unreachable in practice because mac80211
guarantees a minimum TIM length of 4 bytes for non-S1G devices. This
change primarily serves to silence static analysis warnings and keep
the error handling logic complete.

Compile tested only. Issue found using a prototype static analysis tool
and code review.

af60fe4b12 wifi: iwlwifi: acpi: cache the DSM functions
Instead of reading the DSM functions on demand, just read them all
when the first DSM function is called and cache the values for all
the other DSM functions. This simplifies the flow.
Since the same will be done for UEFI in the next patch, remove the
ifdef CONFIG_ACPI around the relevant variables.

Once UEFI's cache will be implemented, we'll be able to change
iwl_bios_get_dsm to access the cache directly.

7a749db26c wifi: iwlwifi: mld: Fix primary link selection logic
When assigning emlsr.primary with emlsr.selected_primary
we are checking if BIT(mld_vif->emlsr.selected_links) are
a part of vif->active_links. This is incorrect as
emlsr.selected_links is a bitmap of possibly two selected links.
Therefore, performing the BIT() operation on it does not
yield any meaningful result and almost always leads to
incorrect primary link selection.

Additionally, we cannot rely on vif->active_links at this
stage of the link switch flow because it contains both the
removed links and also the newly added links.
For example, if we had selected links in the past (0x11)
and we now select links because of TTLM/debugfs (0x100),
vif->active_links will now be (0x111) and primary link
will be 0, while 0 is not even an active link. Thus,
we create our own bitmap of final active links.

d2fcdf3655 wifi: iwlwifi: mld: fix chandef start calculation
A link pair in which both links are in 5 GHz can be used for EMLSR only
if they are separated enough.

To check this condition we calculate the start and the end of the
chandefs of both links in the pair and do some checks.

But the calculation of the start/end of the chandef is currently done
by subtracting/adding half the bandwidth from/to the control channel's
center frequency, when it should really be subtracted/added from/to the
center frequency of the entire chandef.

Fix the wrong calculation.

5f05d20180 wifi: iwlwifi: mld: support TLC command version 6
In version 6, a phy id is added to the tlc command and the sta_id
becomes a sta_mask.

This change is required for NAN:
- in NAN we can have 2 logical stations of the same physical
  station and with the same channel/band (2 NDIs with the same peer) -
  hence the sta_mask.
- In NAN we can have more than one TLC configuration for a single
  station (for example if it operates on more than one channel) - so the
  FW needs to be able to find the right TLC context, based on the phy id.

Populate the new version (for now with a single station id only. The
other ones will be added later when NAN is implemented).

In case the FW has a lower version than that - convert it to the FW
version.
Note that there is some code duplicantion in the conversions to v5
and to v4, but this is intentional since v5 will be removed as soon as
v6 is supported.
