2025-07-15wifi: ath12k: Use HTT_TCL_METADATA_VER_V1 in FTM modeAaradhana Sahu
Currently host sends HTT_TCL_METADATA_VER_V2 to the firmware regardless of the operating mode (Mission or FTM). Firmware expects additional software information (like peer ID, vdev ID, and link ID) in Tx packets when HTT_TCL_METADATA_VER_V2 is set. However, in FTM (Factory Test Mode) mode, no vdev is created on the host side (this is expected). As a result, the firmware fails to find the expected vdev during packet processing and ends up dropping packets. To fix this, send HTT_TCL_METADATA_VER_V1 in FTM mode because FTM mode doesn't support HTT_TCL_METADATA_VER_V2.

2025-07-15can: tcan4x5x: fix reset gpio usage during probeBrett Werling
Fixes reset GPIO usage during probe by ensuring we retrieve the GPIO and take the device out of reset (if it defaults to being in reset) before we attempt to communicate with the device. This is achieved by moving the call to tcan4x5x_get_gpios() before tcan4x5x_find_version() and avoiding any device communication while getting the GPIOs. Once we determine the version, we can then take the knowledge of which GPIOs we obtained and use it to decide whether we need to disable the wake or state pin functions within the device. This change is necessary in a situation where the reset GPIO is pulled high externally before the CPU takes control of it, meaning we need to explicitly bring the device out of reset before we can start communicating with it at all. This also has the effect of fixing an issue where a reset of the device would occur after having called tcan4x5x_disable_wake(), making the original behavior not actually disable the wake. This patch should now disable wake or state pin functions well after the reset occurs.

2025-07-15wifi: rtw89: introduce fw feature group and redefine CRASH_TRIGGERZong-Zhe Yang
Some FW features may have variants on how to deal with in leaf functions, e.g. H2C commands. However, from SW component point of view, it might not matter which variant is supported exactly. In some cases, SW component may just care whether any of the variants is supported or not. So, introduce a concept of FW feature group which can manage a set of FW features and can easily be checked if at least one of them is supported. Since CRASH_TRIGGER will have variants and then matches the case mentioned above, so redefine CRASH_TRIGGER as a FW feature group and add a variant of type 0 for original handling.

2025-07-15wifi: rtw89: mcc: solve GO's TBTT change and TBTT too close to NoA issueChih-Kang Chang
For some implementation acting as GO under MCC(GO+STA), the GO's TBTT might change after STA roams to another AP. This could result the new GO beacon TX at the STA timeslot of GC+STA, causing GC beacon loss. Therefore, if the GC detects beacon loss, it will pause MCC and remain on the GO side for 100 TU to detect the new TBTT beacon. Additionally, some implementation acting as GO under MCC might TX beacon too close to the NoA period. The GC calculates timeslot pattern the TOB (time offset behind) or TOA(time offset ahead) less than the minimum RX beacon time, which leads to beacon loss. Therefore, disable the beacon filter in this case. Then, if the GO's TBTT changed, the pattern TOB/TOA greater than the minimum RX beacon time, the beacon filter should be retriggered during MCC update. Moreover, if the beacon filter is disabled initially but the GO timeslot change, causing QoS null data detection fail, also pause MCC to detect new TBTT beacon.

HW scan of WiFi 7 chips supports multiple op channel configurations. When concurrency, fill two channels info to HW scan to avoid packet lost. However, the OP chan timing is arranged by FW, and the actual stay period depends on AP. It's hard to calculate total scan time for once NoA in advance. Therefore, change the scan back to GO OP channel every 200TU and TX beacon to ensure GC doesn't beacon loss. Additionally, add a period NoA with large duration to ensure GC doesn't TX packet during GO scanning and can still listen beacon at TBTT to update the new NoA info after scan complete.
