====================
wireless-next-2026-07-26

Mostly driver changes this time:
 - new driver mm81x for an S1G device
 - new driver nxpwifi for NXP devices
   (mostly forked off from mwifiex)
 - ath12k: much kernel infrastructure integration work
 - brcmfmac: DPP support, some Cypress part update
 - nl80211: per-link statistics support

<title>mmc: core: add NXP IW61x base ID and block size quirk</title>

<id>dc4d1a7615a72d8671350ea8131cd86576869ab8</id>
<content type='text'>
The NXP IW61x series SDIO chipset identifies itself with a base card ID
(0x0204) during the initial MMC bus scan, while the specific WLAN
function reports a different ID (0x0205).

To ensure that the MMC_QUIRK_BLKSZ_FOR_BYTE_MODE quirk is correctly
inherited by all SDIO functions (including Wi-Fi), it must be attached
to the base card ID at the core level.

Add the SDIO_DEVICE_ID_NXP_IW61X_BASE definition and apply the required
fixup in the SDIO quirk table.

; some of them are widely used headers. To stop mixing up different and
unrelated driver( type)s let the subsystem headers only use the subset
of the recently split &lt;linux/mod_devicetable.h&gt; that are relevant for
them.

The fallout (I hope) is addressed in the previous commits that handle
sources relying on e.g. &lt;linux/i2c.h&gt; pulling in the full legacy header

<title>mmc: core: Avoid bitfield RMW for claim/retune flags</title>

<id>901084c51a0a8fb42a3f37d2e9c62083c495f824</id>
<content type='text'>
Move claimed and retune control flags out of the bitfield word to
avoid unrelated RMW side effects in asynchronous contexts.

The host-&gt;claimed bit shared a word with retune flags. Writes to claimed
in __mmc_claim_host() or retune_now in mmc_mq_queue_rq() can overwrite
other bits when concurrent updates happen in other contexts, triggering
spurious WARN_ON(!host-&gt;claimed). Convert claimed, can_retune,
retune_now and retune_paused to bool to remove shared-word coupling.

Kingston eMMC IY2964 and IB2932 takes a fixed ~2 seconds for each secure
erase/trim operation regardless of size - that is, a single secure
erase/trim operation of 1MB takes the same time as 1GB. With default
calculated 3.5MB max discard size, secure erase 1GB requires ~300 separate
operations taking ~10 minutes total.

Add a card quirk, MMC_QUIRK_FIXED_SECURE_ERASE_TRIM_TIME, to set maximum
secure erase size for those devices. This allows 1GB secure erase to
complete in a single operation, reducing time from 10 minutes to just 2
seconds.
