db49e22ae2 New boards are the Rock Pi 4, NanoPC-T4 and NanoPi-M4, with the last
two being part of a family and sharing bigger parts of the devicetree.
 rk3328 got sound-related upgrades and a wider patch drops mmc display-wp
 fields from nodes which shouldn't use it.

3f4da372ec EDAC/mce_amd: Decode MCA_STATUS[Scrub] bit
Previous AMD systems have had a bit in MCA_STATUS to indicate that an
error was detected on a scrub operation. However, this bit was defined
differently within different banks and families/models.

Starting with Family 17h, MCA_STATUS[40] is either Reserved/Read-as-Zero
or defined as "Scrub", for all MCA banks and CPU models. Therefore, this
bit can be defined as the "Scrub" bit.

Define MCA_STATUS[40] as "Scrub" and decode it in the AMD MCE decoding
module for Family 17h and newer systems.

77ab2ebf93 New board the Elgin-R1 based on the rv1108 soc and a number of small
improvements for rv1108 as well. RK3066 got support for the core
 display components and the Edison tablet got its touchscreen added.
 Apart from that a wider fix to drop display-wp usage from places where
 it shouldn't be used, a pin fix for Edison and a cleanup to prevent
 rk3036 board from defining sound-dai-cells for core components in
 each board separately.

d9e61b66a5 drm/i915: Defer application of request banning to submission
As we currently do not check on submission whether the context is banned
in a timely manner it is possible for some requests to escape
cancellation after their parent context is banned. By moving the ban
into the request submission under the engine->timeline.lock, we
serialise it with the reset and setting of the context ban.

SoC updates for ti81xx for v5.1 merge window

Two changes to add legacy hwmod data for gpio and spi peripherals on
ti81xx. We have not yet updated ti81xx to probe devices with ti-sysc
interconnect target module driver, so these changes are still needed
to make devices usable for the related device tree changes.

83e37e0bdd mac80211: Restore vif beacon interval if start ap fails
The starting of AP interface can fail due to invalid
beacon interval, which does not match the minimum gcd
requirement set by the wifi driver. In such case, the
beacon interval of that interface gets updated with
that invalid beacon interval.

The next time that interface is brought up in AP mode,
an interface combination check is performed and the
beacon interval is taken from the previously set value.

In a case where an invalid beacon interval, i.e. a beacon
interval value which does not satisfy the minimum gcd criteria
set by the driver, is set, all the subsequent trials to
bring that interface in AP mode will fail, even if the
subsequent trials have a valid beacon interval.

To avoid this, in case of a failure in bringing up an
interface in AP mode due to interface combination error,
the interface beacon interval which is stored in bss
conf, needs to be restored with the last working value
of beacon interval.

Tested on ath10k using WCN3990.

b4c3fbe636 mac80211: Use linked list instead of rhashtable walk for mesh tables
The mesh table code walks over hash tables for two purposes.  First of
all it's used as part of a netlink dump process, but it is also used
for looking up entries to delete using criteria other than the hash
key.

The second purpose is directly contrary to the design specification
of rhashtable walks.  It is only meant for use by netlink dumps.

This is because rhashtable is resizable and you cannot obtain a
stable walk over it during a resize process.

In fact mesh's use of rhashtable for dumping is bogus too.  Rather
than using rhashtable walk's iterator to keep track of the current
position, it always converts the current position to an integer
which defeats the purpose of the iterator.

Therefore this patch converts all uses of rhashtable walk into a
simple linked list.

This patch also adds a new spin lock to protect the hash table
insertion/removal as well as the walk list modifications.  In fact
the previous code was buggy as the removals can race with each
other, potentially resulting in a double-free.

prime the system with a hanging spinner before performing a full-device
reset. (Figuring out the root cause behind the instability with handling
a reset during a no-op request is a challenge for another test, the
whitelist test has its own purpose.)

2e57b7cebb i2c: aspeed: Add multi-master use case support
In multi-master environment, this driver's master cannot know
exactly when a peer master sends data to this driver's slave so
cases can be happened that this master tries sending data through
the master_xfer function but slave data from a peer master is still
being processed or slave xfer is started by a peer immediately
after it queues a master command. To support multi-master use cases
properly, this H/W provides arbitration in physical level and it
provides priority based command handling too to avoid conflicts in
multi-master environment, means that if a master and a slave events
happen at the same time, H/W will handle a higher priority event
first and a pending event will be handled when bus comes back to
the idle state.

To support this H/W feature properly, this patch adds the 'pending'
state of master and its handling code so that the pending master
xfer can be continued after slave operation properly.

f275a46594 i2c: bcm2835: Clear current buffer pointers and counts after a transfer
The driver's interrupt handler checks whether a message is currently
being handled with the curr_msg pointer. When it is NULL, the interrupt
is considered to be unexpected. Similarly, the i2c_start_transfer
routine checks for the remaining number of messages to handle in
num_msgs.

However, these values are never cleared and always keep the message and
number relevant to the latest transfer (which might be done already and
the underlying message memory might have been freed).

When an unexpected interrupt hits with the DONE bit set, the isr will
then try to access the flags field of the curr_msg structure, leading
to a fatal page fault.

The msg_buf and msg_buf_remaining fields are also never cleared at the
end of the transfer, which can lead to similar pitfalls.

Fix these issues by introducing a cleanup function and always calling
it after a transfer is finished.
