5ef8c66541 wireless-drivers-next patches for v5.7
Second set of patches for v5.7. Lots of cleanup patches this time, but
 of course various new features as well fixes.
 
 When merging with wireless-drivers this pull request has a conflict in:
 
 drivers/net/wireless/intel/iwlwifi/pcie/drv.c
 
 To solve that just drop the changes from commit cf52c8a776 in
 wireless-drivers and take the hunk from wireless-drivers-next as is.
 The list of specific subsystem device IDs are not necessary after
 commit d6f2134a38 (in wireless-drivers-next) anymore, the detection
 is based on other characteristics of the devices.
 
 Major changes:
 
 qtnfmac
 
 * support WPA3 SAE and OWE in AP mode
 
 ath10k
 
 * support for getting btcoex settings from Device Tree
 
 * support QCA9377 SDIO device
 
 ath11k
 
 * add HE rate accounting
 
 * add thermal sensor and cooling devices
 
 mt76
 
 * MT7663 support for the MT7615 driver

11a64888c7 rtw88: 8822c: config RF table path B before path A
After MAC switched power, the hardware's RF registers will have
its default value, but the default value for path B is incorrect.
So, load RF path B first, to decrease the period between MAC on
and RF path B config.

By test, if we load path A first, then there's ~300ms that the
path B is incorrect, it could lead to BT coex's A2DP glitch.
But if we configure path B first, there will only have ~3ms,
significantly lower possibility to have A2DP sound glitch.

aaab5d0e67 rtw88: kick off TX packets once for higher efficiency
Driver used to kick off every TX packets, that will waste some
time while we can do better to kick off the TX packets once after
they are all prepared to be transmitted.

For PCI, it uses DMA engine to transfer the SKBs to the device,
and the transition of the state of the DMA engine could be a cost.
Driver can save some time to kick off multiple SKBs once so that
the DMA engine will have only one transition.

So, split rtw_hci_ops::tx() to rtw_hci_ops::tx_write() and
rtw_hci_ops::tx_kick_off() to explicitly kick the SKBs off after
they are written to the prepared buffer. For packets come from
ieee80211_ops::tx(), write one and then kick it off immediately.
For packets queued in TX queue, which come from
ieee80211_ops::wake_tx_queue(), we can dequeue them, write them
to the buffer, and then kick them off together.

895c096dab rtw88: associate reserved pages with each vif
Each device has only one reserved page shared with all of the
vifs, so it seems not reasonable to pass vif as one of the
arguments to rtw_fw_download_rsvd_page(). If driver is going
to run more than one vif, the content of reserved page could
not be built for all of the vifs.

To fix it, let each vif maintain its own reserved page list,
and build the final reserved page to download to the firmware
from all of the vifs. Hence driver should add reserved pages
to each vif according to the vif->type when adding the vif.

For station mode, add reserved page with rtw_add_rsvd_page_sta().
If the station mode is going to suspend in PNO (net-detect)
mode, remove the reserved pages used for normal mode, and add
new one for wowlan mode with rtw_add_rsvd_page_pno().

For beacon mode, only beacon is required to be added using
rtw_add_rsvd_page_bcn().

This would make the code flow simpler as we don't need to
add reserved pages when vif is running, just add/remove them
when ieee80211_ops::[add|remove]_interface.

When driver is going to download the reserved page, it will
collect pages from all of the vifs, this list is maintained
by rtwdev, with build_list as the pages' member. That way, we
can still build a list of reserved pages to be downloaded.
Also we can get the location of the pages from the list that
is maintained by rtwdev.

The biggest problem is that the first page should always be
beacon, if other type of reserved page is put in the first
page, the tx descriptor and offset could be wrong.
But station mode vif does not add beacon into its list, so
we need to add a dummy page in front of the list, to make
sure other pages will not be put in the first page. As the
dummy page is allocated when building the list, we must free
it before building a new list of reserved pages to firmware.

Extract skb allocation routines for rsvd_page and h2c.
These routines should also be used by USB and SDIO.

This should not change the logic at all.
memset() for pkt_info is unnecessary, just declare as {0}.
Also skb_put()/memcpy() can be replaced by skb_put_data().

57fb39e247 rtw88: don't hold all IRQs disabled for PS operations
This driver generally only needs to ensure that
(a) it doesn't try to process TX interrupts at the same time as
    power-save operations (and similar)
(b) the device interrupt gets disabled while we're still handling the
    last set of interrupts

For (a), all the operations (e.g., PS transitions, packet handling)
happens in non-atomic contexts (e.g., threaded IRQ).

For (b), we only need mutual exclusion for brief sections (i.e., while
we're actually manipulating the interrupt mask/status).

So, we can introduce a separate lock for handling (b), disabling IRQs
while we do it. For (a), we can demote the locking to BH only, now that
(b) (the only steps done in atomic context) and that has its own lock.

This helps reduce the amount of time this driver spends with IRQs off.
Notably, transitioning out of power-save modes can take >3 milliseconds,
and this transition is done under the protection of 'irq_lock'.

53efdc9cb9 wl3501_cs: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.
