Add support for a new devicetree compatible string called
'amazon,alpine-apb-ssi', which is necessary for the Amazon Alpine spi
controller. 'amazon,alpine-dw-apb-ssi' is used in the dw spi driver if
specified in the devicetree. Otherwise, fall back to driver default
behavior, i.e. original dw IP hw driver behavior.

This compatible adds the ability for dw spi controller driver to work with
the dw spi controller found on Alpine chips.
The dw spi controller has an auto-deselect of Chip-Select, in case there is
no data inside the Tx FIFO. While working on platforms with Alpine chips,
auto-deselect mode causes an issue for some spi devices that can't handle
the Chip-Select deselect in the middle of a transaction. It is a normal
behavior for a Tx FIFO to be empty in the middle of a transaction, due to
busy cpu. In the Alpine chip family an option to change the default
behavior was added to the original dw spi controller to prevent this issue
of de-asserting Chip-Select once TX FIFO is empty. The change was to allow
SW manual control of the Chip-Select. With this change, as long as the
Slave Enable Register is asserted, the Chip-Select will be asserted. As a
result, it is necessary to deselect the Slave Select Register once the
transaction is done. This feature is enabled via a new device compatible
string called 'amazon,alpine-dw-apb-ssi'. Once the driver identifies the
new compatible string, it enables the hw fixup logic, by writing to a
dedicated register found in the IP reserved area and will start manual
deselecting the Slave Select Register when the transfer ends.

Immutable branch for QCOM Geni patches

Previous implementation of SAE authentication in infrastructure BSS was
somewhat restricting and not exactly clean way of handling the two
auth() operations. This ended up removing and re-adding the STA entry
for the AP in the middle of authentication and also messing up
authentication state tracking through the sequence of four
Authentication frames. Furthermore, this did not work if the AP ended up
sending out SAE Confirm (auth trans #2) immediately after SAE Commit
(auth trans #1) before the station had time to transmit its SAE Confirm.
Clean up authentication state handling for the SAE case to allow two
rounds of auth() calls without dropping all state between those
operations. Track peer Confirmed status and mark authentication
completed only once both ends have confirmed.
ieee80211_mgd_auth() check for EBUSY cases is now handling only the
pending association (ifmgd->assoc_data) while all pending authentication
(ifmgd->auth_data) cases are allowed to proceed to allow user space to
start a new connection attempt from scratch even if the previously
requested authentication is still waiting completion. This is needed to
avoid making SAE error cases with retries take excessive amount of time
with no means for the user space to stop that (apart from setting the
netdev down).
As an extra bonus, the end of ieee80211_rx_mgmt_auth() can be cleaned up
to avoid the extra copy of the cfg80211_rx_mlme_mgmt() call for ongoing
SAE authentication since the new ieee80211_mark_sta_auth() helper
function can handle both completion of authentication and updates to the
STA entry under the same condition and there is no need to return from
the function between those operations.

This makes it easier to conditionally replace full allocation of
auth_data to use reallocation for the case of continuing SAE
authentication. Furthermore, there was not really any point in having
this check done so late in the function after having already completed
number of steps that cannot be used anyway in the error case.

When there are few packets (e.g. for sampling attempts), the exponentially

Long/short preamble selection cannot be sampled separately, since it
depends on the BSS state. Because of that, sampling attempts to
currently not used preamble modes are not counted in the statistics,
which leads to CCK rates being sampled too often.
Fix statistics accounting for long/short preamble by increasing the
index where necessary.
Fix excessive CCK rate sampling by dropping unsupported sample attempts.

I'm not really sure exactly _why_ I've been carrying a note
for what's probably _years_ to check that we don't do this,
but we clearly do reflect frames back to the station itself
if it sends such.
One way or the other, it's useless since the station doesn't
really need the AP to talk to itself, so suppress it.
While at it, clarify some of the logic by removing skb->data
references in favour of the destination address (pointer) we
already have separately.

Fixing/optimizing bcm_qspi_bspi_read() performance introduced two
changes:
1) It added a loop to read all requested data using multiple BSPI ops.
2) It bumped max size of a single BSPI block request from 256 to 512 B.
The later change resulted in occasional BSPI timeouts causing a
regression.
For some unknown reason hardware doesn't always handle reads as expected
when using 512 B chunks. In such cases it may happen that BSPI returns
amount of requested bytes without the last 1-3 ones. It provides the
remaining bytes later but doesn't raise an interrupt until another LR
start.
Switching back to 256 B reads fixes that problem and regression.

The DTK-2451 and DTH-2452 have a buggy HID descriptor which incorrectly
contains a Cintiq-like report, complete with pen tilt, rotation, twist, serial
number, etc. The hardware doesn't actually support this data but our driver
duitifully sets up the device as though it does. To ensure userspace has a
correct view of devices without updated firmware, we clean up this incorrect
data in wacom_setup_device_quirks.
We're also careful to clear the WACOM_QUIRK_TOOLSERIAL flag since its presence
causes the driver to wait for serial number information (via
wacom_wac_pen_serial_enforce) that never comes, resulting in
the pen being non-responsive.

With a very low cpu.cfs_quota_us setting, such as the minimum of 1000,
distribute_cfs_runtime may not empty the throttled_list before it runs
out of runtime to distribute. In that case, due to the change from
c06f04c7048 to put throttled entries at the head of the list, later entries
on the list will starve. Essentially, the same X processes will get pulled
off the list, given CPU time and then, when expired, get put back on the
head of the list where distribute_cfs_runtime will give runtime to the same
set of processes leaving the rest.
Fix the issue by setting a bit in struct cfs_bandwidth when
distribute_cfs_runtime is running, so that the code in throttle_cfs_rq can
decide to put the throttled entry on the tail or the head of the list. The
bit is set/cleared by the callers of distribute_cfs_runtime while they hold
cfs_bandwidth->lock.
This is easy to reproduce with a handful of CPU consumers. I use 'crash' on
the live system. In some cases you can simply look at the throttled list and
see the later entries are not changing:
crash> list cfs_rq.throttled_list -H 0xffff90b54f6ade40 -s cfs_rq.runtime_remaining | paste - - | awk '{print $1" "$4}' | pr -t -n3

In tipc_sk_filter_rcv(), when we detect protocol messages with error we
call tipc_sk_conn_proto_rcv() and let it reset the connection and notify
the socket by calling sk->sk_state_change().
However, tipc_sk_filter_rcv() may have been called from the function
tipc_backlog_rcv(), in which case the socket lock is held and the socket
already awake. This means that the sk_state_change() call is ignored and
the error notification lost. Now the receive queue will remain empty and
the socket sleeps forever.
In this commit, we convert the protocol message into a connection abort
message and enqueue it into the socket's receive queue. By this addition
to the above state change we cover all conditions.

In the patch referred to below we added link tolerance as an additional
criteria for declaring broadcast transmission "stale" and resetting the
affected links.
However, the 'tolerance' field of the broadcast link is never set, and
remains at zero. This renders the whole commit without the intended
improving effect, but luckily also with no negative effect.
In this commit we add the missing initialization.

In case of error, the function syscon_node_to_regmap() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

There is no reason to open code what the switch setup function does, in
fact, because we just issued a switch reset, we would make all the
register get their default values, including for instance, having unused
port be enabled again and wasting power and leading to an inappropriate
switch core clock being selected.
