Pull pin control fixes from Linus Walleij:
- One Intel patch that I mistakenly merged into for-next despite it
belonging in fixes: add Arrow Lake-H/U ACPI ID so this Arrow Lake
chip probes.
- One fix making the CY895x0 reg cache work, which is good because it
makes the device work too.

Make the integrity mapping more like data mapping, blk_rq_map_sg. Use
the request to validate the segment count, and update the callers so
they don't have to.

Another device has been reported to be unreliable if we have more than

Since we have two devices now needing this quirky behavior, make a

The same Apple quirk is clearly not "temporary", so update the comment
while moving it.

bo_meminfo() wants to inspect bo state like tt and the ttm resource,
however this state can change at any point leading to stuff like NPD and
UAF, if the bo lock is not held. Grab the bo lock when calling
bo_meminfo(), ensuring we drop any spinlocks first. In the case of
object_idr we now also need to hold a ref.

There is a real deadlock as well as sleeping in atomic() bug in here, if
the bo put happens to be the last ref, since bo destruction wants to
grab the same spinlock and sleeping locks. Fix that by dropping the ref
using xe_bo_put_deferred(), and moving the final commit outside of the
lock. Dropping the lock around the put is tricky since the bo can go
out of scope and delete itself from the list, making it difficult to
navigate to the next list entry.

25216afc9db5 ("PCI: Add managed pcim_intx()") moved the allocation step for
pci_intx()'s device resource from pcim_enable_device() to pcim_intx(). As
before, pcim_enable_device() sets pci_dev.is_managed to true; and it is
never set to false again.
Due to the lifecycle of a struct pci_dev, it can happen that a second
driver obtains the same pci_dev after a first driver ran. If one driver
uses pcim_enable_device() and the other doesn't, this causes the other
driver to run into managed pcim_intx(), which will try to allocate when
called for the first time.
Allocations might sleep, so calling pci_intx() while holding spinlocks
becomes then invalid, which causes lockdep warnings and could cause
deadlocks:

The TAS module could not be configured when it's running in pending
status. We need disable the module and configure it again. However, the
pending status is not cleared after the module disabled. TC taprio set
will always return busy even it's disabled.
For example, a user uses tc-taprio to configure Qbv and a future
basetime. The TAS module will run in a pending status. There is no way
to reconfigure Qbv, it always returns busy.
Actually the TAS module can be reconfigured when it's disabled. So it
doesn't need to check the pending status if the TAS module is disabled.
After the patch, user can delete the tc taprio configuration to disable
Qbv and reconfigure it again.

Avoid unnecessary nested min()/max() which results in egregious macro
expansion.
Use clamp_t() as this introduces the least possible expansion, and turn
the {s,u}DIGIT_FITTING() macros into inline functions to avoid the
nested expansion.
This resolves an issue with slackware 15.0 32-bit compilation as
reported by Richard Narron.
Presumably the min/max fixups would be difficult to backport, this patch
should be easier and fix's Richard's problem in 5.15.

[Why]
DC has a special commit path for native cursor, which use the built-in
cursor pipe within DCN planes. This update path does not require all
enabled planes to be added to the list of surface updates sent to DC.
This is not the case for overlay cursor; it uses the same path as MPO
commits. This update path requires all enabled planes to be added to the
list of surface updates sent to DC. Otherwise, DC will disable planes
not inside the list.
[How]
If overlay cursor is needed, add all planes on the same CRTC as this
cursor to the atomic state. This is already done for non-cursor planes
(MPO), just before the added lines.

for non-continous port maps"
This reverts commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 because it
breaks codecs using non-continuous masks in source and sink ports. The
commit missed the point that port numbers are not used as indices for
iterating over prop.sink_ports or prop.source_ports.
Soundwire core and existing codecs expect that the array passed as
prop.sink_ports and prop.source_ports is continuous. The port mask still
might be non-continuous, but that's unrelated.

The probe() function is only used for DP83822 and DP83826 PHY,
leaving the private data pointer uninitialized for the DP83825 models
which causes a NULL pointer dereference in the recently introduced/changed
functions dp8382x_config_init() and dp83822_set_wol().
Add the dp8382x_probe() function, so all PHY models will have a valid
private data pointer to fix this issue and also prevent similar issues
in the future.
