[WHY]
Some eDP panels's ext caps don't write initial value cause the value of
dpcd_addr(0x317) is random. It means that sometimes the eDP will
clarify it is OLED, miniLED...etc cause the backlight control interface
is incorrect.
[HOW]
Add a new panel patch to remove sink ext caps(HDR,OLED...etc)

Currently sync thread is stopped from multiple contex:
- idle_sync_thread
- frozen_sync_thread
- __md_stop_writes
- md_set_readonly
- do_md_stop
And there are some problems:
1) sync_work is flushed while reconfig_mutex is grabbed, this can
deadlock because the work function will grab reconfig_mutex as well.
2) md_reap_sync_thread() can't be called directly while md_do_sync() is
not finished yet, for example, commit 130443d60b1b ("md: refactor
idle/frozen_sync_thread() to fix deadlock").
3) If MD_RECOVERY_RUNNING is not set, there is no need to stop
sync_thread at all because sync_thread must not be registered.
Factor out a helper stop_sync_thread(), so that above contex will behave
the same. Fix 1) by flushing sync_work after reconfig_mutex is released,
before waiting for sync_thread to be done; Fix 2) bt letting daemon thread
to unregister sync_thread; Fix 3) by always checking MD_RECOVERY_RUNNING
first.

If md_set_readonly() failed, the array could still be read-write, however
'MD_RECOVERY_FROZEN' could still be set, which leave the array in an
abnormal state that sync or recovery can't continue anymore.
Hence make sure the flag is cleared after md_set_readonly() returns.

Commit ac619781967b ("md: use separate work_struct for md_start_sync()")
use a new sync_work to replace del_work, however, stop_sync_thread() and
__md_stop_writes() was trying to wait for sync_thread to be done, hence
they should switch to use sync_work as well.
Noted that md_start_sync() from sync_work will grab 'reconfig_mutex',
hence other contex can't held the same lock to flush work, and this will
be fixed in later patches.

Arm FF-A fixes for v6.7
A bunch of fixes addressing issues around the notification support that
was added this cycle. They address issue in partition IDs handling in
ffa_notification_info_get(), notifications cleanup path and the size of
the allocation in ffa_partitions_cleanup().
It also adds check for the notification enabled state so that the drivers
registering the callbacks can be rejected if not enabled/supported.
It also moves the partitions setup operation after the notification
initialisation so that the driver has the correct state for notification
enabled/supported before the partitions are initialised/setup.
It also now allows FF-A initialisation to complete successfully even
when the notification initialisation fails as it is an optional support
in the specification. Initial support just allowed it only if the
firmware didn't support notifications.
Finally, it also adds a fix for smatch warning by declaring ffa_bus_type
structure in the header.

Invoke drm_plane_helper_funcs.end_fb_access before
drm_atomic_helper_commit_hw_done(). The latter function hands over
ownership of the plane state to the following commit, which might
free it. Releasing resources in end_fb_access then operates on undefined
state. This bug has been observed with non-blocking commits when they
are being queued up quickly.
Here is an example stack trace from the bug report. The plane state has
been free'd already, so the pages for drm_gem_fb_vunmap() are gone.

Fix this by running end_fb_access immediately after updating all planes
in drm_atomic_helper_commit_planes(). The existing clean-up helper
drm_atomic_helper_cleanup_planes() now only handles cleanup_fb.
For aborted commits, roll back from drm_atomic_helper_prepare_planes()
in the new helper drm_atomic_helper_unprepare_planes(). This case is
different from regular cleanup, as we have to release the new state;
regular cleanup releases the old state. The new helper also invokes
cleanup_fb for all planes.
The changes mostly involve DRM's atomic helpers. Only two drivers, i915
and nouveau, implement their own commit function. Update them to invoke
drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail
function do not require changes.
v4:
* fix documentation (kernel test robot)

* add drm_atomic_helper_unprepare_planes() for rolling back

This reverts commit 4baf1218150985ee3ab0a27220456a1f027ea0ac.
Enabling runtime pm as default for all AMD xHC 1.1 controllers caused
regression. An initial attempt to fix those was done in commit a5d6264b638e
("xhci: Enable RPM on controllers that support low-power states") but new
issues are still seen.
Revert this to get those AMD xHC 1.1 systems working
This patch went to stable an needs to be reverted from there as well.

In __iavf_set_coalesce, the driver checks both ec->rx_coalesce_usecs and
ec->tx_coalesce_usecs for validity. It does this via a chain if if/else-if
blocks. If every single branch of the series of if statements exited, this
would be fine. However, the rx_coalesce_usecs is checked against zero to
print an informative message if use_adaptive_rx_coalesce is enabled. If
this check is true, it short circuits the entire chain of statements,
preventing validation of the tx_coalesce_usecs field.
Indeed, since commit e792779e6b63 ("iavf: Prevent changing static ITR
values if adaptive moderation is on") the iavf driver actually rejects any
change to the tx_coalesce_usecs or rx_coalesce_usecs when
use_adaptive_tx_coalesce or use_adaptive_rx_coalesce is enabled, making
this checking a bit redundant.
Fix this error by removing the unnecessary and redundant checks for
use_adaptive_rx_coalesce and use_adaptive_tx_coalesce. Since zero is a
valid value, and since the tx_coalesce_usecs and rx_coalesce_usecs fields
are already unsigned, remove the minimum value check. This allows assigning
an ITR value ranging from 0-8160 as described by the printed message.

Commit 3a2c6ced90e1 ("i40e: Add a check to see if MFS is set") added
a warning message that reports unexpected size of port's MFS (max
frame size) value. This message use for the port number local
variable 'i' that is wrong.
In i40e_probe() this 'i' variable is used only to iterate VSIs
to find FDIR VSI:
<code>
...
/* if FDIR VSI was set up, start it now */
for (i = 0; i < pf->num_alloc_vsi; i++) {
if (pf->vsi[i] && pf->vsi[i]->type == I40E_VSI_FDIR) {
i40e_vsi_open(pf->vsi[i]);
break;
}
}
...
</code>
So the warning message use for the port number index of FDIR VSI
if this exists or pf->num_alloc_vsi if not.
Fix the message by using 'pf->hw.port' for the port number.

The rvu_dl will be freed in rvu_npa_health_reporters_destroy(rvu_dl)
after the create_workqueue fails, and after that free, the rvu_dl will
be translate back through rvu_npa_health_reporters_create,
rvu_health_reporters_create, and rvu_register_dl. Finally it goes to the
err_dl_health label, being freed again in
rvu_health_reporters_destroy(rvu) by rvu_npa_health_reporters_destroy.
In the second calls of rvu_npa_health_reporters_destroy, however,
it uses rvu_dl->rvu_npa_health_reporter, which is already freed at
the end of rvu_npa_health_reporters_destroy in the first call.
So this patch prevents the first destroy by instantly returning -ENONMEN
when create_workqueue fails. In addition, since the failure of
create_workqueue is the only entrence of label err, it has been
integrated into the error-handling path of create_workqueue.

Apparently some BXT/GLK systems have DSI panels whose timings
don't agree with the normal cpu transcoder hblank>=32 limitation.
This is perhaps fine as there are no specific hblank/etc. limits
listed for the BXT/GLK DSI transcoders.
Move those checks out from the global intel_mode_valid() into
into connector specific .mode_valid() hooks, skipping BXT/GLK
DSI connectors. We'll leave the basic [hv]display/[hv]total
checks in intel_mode_valid() as those seem like sensible upper
limits regardless of the transcoder used.

commit 5ef216c1f848 ("arcnet: com20020-pci: add rotary index support")
changes the device name of all COM20020 based PCI cards,
even if only some cards support this:
snprintf(dev->name, sizeof(dev->name), "arc%d-%d", dev->dev_id, i);
The error happens because all Sohard Arcnet cards would be called arc0-0,
since the Sohard Arcnet cards don't have a PLX rotary coder.
I.e. EAE Arcnet cards have a PLX rotary coder,
which sets the first decimal, ensuring unique devices names.
This patch adds two new card feature flags to indicate
which cards support LEDs and the PLX rotary coder.
For EAE based cards the names still depend on the PLX rotary coder
(untested, since missing EAE hardware).
For Sohard based cards, this patch will result in devices
being called arc0, arc1, ... (tested).

The VA addresses are coming from rdma-core in this diagram can be
arbitrary, but for 64k pages, the VA may be offset by some number of HCA
4k pages and followed by some number of HCA 4k pages.
The current iterator doesn't account for either the preceding 4k pages or
the following 4k pages.
Fix the issue by extending the ib_block_iter to contain the number of DMA
pages like comment [1] says and by using __sg_advance to start the
iterator at the first live HCA page.
The changes are contained in a parallel set of iterator start and next
functions that are umem aware and specific to umem since there is one user
of the rdma_for_each_block() without umem.
These two fixes prevents the extra pages before and after the user MR
data.
Fix the preceding pages by using the __sq_advance field to start at the
first 4k page containing MR data.
Fix the following pages by saving the number of pgsz blocks in the
iterator state and downcounting on each next.
This fix allows for the elimination of the small page crutch noted in the
Fixes.
