====================
wireless-drivers fixes for v5.12

Third, and last, set of fixes for v5.12. Small fixes, iwlwifi having
most of them. brcmfmac regression caused by cfg80211 changes is the
most important here.

iwlwifi

* fix a lockdep warning

* fix regulatory feature detection in certain firmware versions

* new hardware support

* fix lockdep warning

* mvm: fix beacon protection checks

mt76

* mt7921: fix airtime reporting

brcmfmac

* fix a deadlock regression
====================

brcmfmac: p2p: Fix recently introduced deadlock issue

2021-03-23T09:37:15+00:00

Commit a05829a7222e ("cfg80211: avoid holding the RTNL when calling the
driver") replaced the rtnl_lock parameter passed to various brcmf
functions with just lock, because since that commit it is not just
about the rtnl_lock but also about the wiphy_lock .

During this search/replace the "if (!rtnl_locked)" check in brcmfmac/p2p.c
was accidentally replaced with "if (locked)", dropping the inversion of
the check. This causes the code to now call rtnl_lock() while already
holding the lock, causing a deadlock.

Add back the "!" to the if-condition to fix this.

module: remove never implemented MODULE_SUPPORTED_DEVICE

2021-03-17T20:16:18+00:00

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was
implemented. We can safely remove it, because the kernel has grown
to have many more reliable mechanisms to determine if device is
supported or not.

b43: N-PHY: Fix the update of coef for the PHY revision >= 3case

2021-02-15T20:40:41+00:00

The documentation for the PHY update [1] states:

Loop 4 times with index i

    If PHY Revision >= 3
        Copy table[i] to coef[i]
    Otherwise
        Set coef[i] to 0

the copy of the table to coef is currently implemented the wrong way
around, table is being updated from uninitialized values in coeff.
Fix this by swapping the assignment around.

brcmfmac: add support for CQM RSSI notifications

2021-02-09T07:57:02+00:00

Add support for CQM RSSI measurement reporting and advertise the
NL80211_EXT_FEATURE_CQM_RSSI_LIST feature. This enables a userspace
supplicant such as iwd to be notified of changes in the RSSI for roaming
and signal monitoring purposes.

brcmsmac: fix alignment constraints

2021-02-08T11:03:22+00:00

sturct d11txh contains a ieee80211_rts structure, which is required to
have at least two byte alignment, and this conflicts with the __packed
attribute:

drivers/net/wireless/broadcom/brcm80211/brcmsmac/d11.h:786:1: warning: alignment 1 of 'struct d11txh' is less than 2 [-Wpacked-not-aligned]

Mark d11txh itself as having two-byte alignment to ensure the
inner structure is properly aligned.

brcmfmac: Add DMI nvram filename quirk for Voyo winpad A15 tablet

2021-02-08T11:02:41+00:00

The Voyo winpad A15 tablet contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt
as nvram file which is a bit too generic.

Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Voyo winpad A15 tablet.

While preparing a matching linux-firmware update I noticed that the nvram
is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
quirk entry simply points to the already existing Prowise-PT301 nvram file.
