Per the SD Host Controller Simplified Specification v4.20 §3.2.3, change
the SD card clock parameters only after first disabling the external card
clock. Doing this fixes a spurious clock pulse on Baytrail and Apollo Lake
SD controllers which otherwise breaks voltage switching with a specific
Swissbit SD card.

FEAT_PMUv3p9 registers such as PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1
access from EL1 requires appropriate EL2 fine grained trap configuration
via FEAT_FGT2 based trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2.
Otherwise such register accesses will result in traps into EL2.
Add a new helper __init_el2_fgt2() which initializes FEAT_FGT2 based fine
grained trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2 (setting the
bits nPMICNTR_EL0, nPMICFILTR_EL0 and nPMUACR_EL1) to enable access into
PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 registers.
Also update booting.rst with SCR_EL3.FGTEn2 requirement for all FEAT_FGT2
based registers to be accessible in EL2.

Currently, we don't select a link that wasn't heared in the last 5
seconds.
But if the link started to suffer from missed beacons more recent than
that, we might select this link even we really shouldn't,
leading to a disconnection instead of a link switch.
Fix this by checking if a link was heared in the last MLO scan,
if not - don't include it in the link selection.
Since we do an MLO scan on missed beacons, we will not hear that link in
that scan, and won't select it.

This is true also if the connection doesn't have EMLSR capability,

According to the requirements, if the last scan isn't older than 20
seconds, we can use its results and do the link selection without
scanning before.
But this applies only when trying to get back to EMLSR, not if the link
has bad RSSI/missed beacons.
Since an MLO scan is cheap anyway, and results from 20 seconds before
are really old, always scan before links switching.

logic to the station logic as it is not related to TLC.
- As long as the station is not associated, set RC A-MSDU maximal
lengths to 1, to prevent iwlmld and mac80211 from building A-MSDUs.

Due to the iwl_mld_get_chandef_from_chanctx() logic, even after
the OMI handshake to reduce bandwidth the driver wouldn't apply
that to the PHY context, since it always uses the normal, not
the reduced, configuration on 6 GHz (not strictly always, but
OMI will only apply if the original bandwidth is > 80 MHz.) Fix
this by making that selection contingent on AP mode. Refactor
the code a bit to also make it clearer why the min_def isn't
used in that case (for FILS.)

Since iwlmld claims wiphys to be self-managed, it needs to
have a regdomain registered before the wiphy is registered
to avoid issues when trying to get the regdomain, e.g. via
"iw phy phy0 reg get".
Move the initialization early, on every FW start not just
when starting to really operate it. This also requires the

If the user disables power save of a vif that didn't have it enabled
(for example before association), mac80211 will not notify the driver
with BSS_CHANGED_PS. This will cause the driver to not update the

Fix this by checking the vif's power save status upon authorization, and
stop considering the vif's power save status on disassociation.

When a device performs DMA to a shared buffer using physical addresses,
(without Stage1 translation), the device must use the "{I}PA address" with the
top bit set in Realm. This is to make sure that a trusted device will be able
to write to shared buffers as well as the protected buffers. Thus, a Realm must
always program the full address including the "protection" bit, like AMD SME
encryption bits.
Enable this by providing arm64 specific dma_addr_{encrypted, canonical}
helpers for Realms. Please note that the VMM needs to similarly make sure that
the SMMU Stage2 in the Non-secure world is setup accordingly to map IPA at the
unprotected alias.

AMD SME added __sme_set/__sme_clr primitives to modify the DMA address for
encrypted/decrypted traffic. However this doesn't fit in with other models,
e.g., Arm CCA where the meanings are the opposite. i.e., "decrypted" traffic
has a bit set and "encrypted" traffic has the top bit cleared.
In preparation for adding the support for Arm CCA DMA conversions, convert the
existing primitives to more generic ones that can be provided by the backends.
i.e., add helpers to
1. dma_addr_encrypted - Convert a DMA address to "encrypted" [ == __sme_set() ]
2. dma_addr_unencrypted - Convert a DMA address to "decrypted" [ None exists today ]
3. dma_addr_canonical - Clear any "encryption"/"decryption" bits from DMA
address [ SME uses __sme_clr() ] and convert to a canonical DMA address.
Since the original __sme_xxx helpers come from linux/mem_encrypt.h, use that
as the home for the new definitions and provide dummy ones when none is provided
by the architectures.
With the above, phys_to_dma_unencrypted() uses the newly added dma_addr_unencrypted()
helper and to make it a bit more easier to read and avoid double conversion,
provide __phys_to_dma().

There are a few problems in this code:
First, if amd_pmf_tee_init() fails then the function returns directly
instead of cleaning up. We cannot simply do a "goto error;" because
the amd_pmf_tee_init() cleanup calls tee_shm_free(dev->fw_shm_pool);
and amd_pmf_tee_deinit() calls it as well leading to a double free.
I have re-written this code to use an unwind ladder to free the
allocations.
Second, if amd_pmf_start_policy_engine() fails on every iteration though
the loop then the code calls amd_pmf_tee_deinit() twice which is also a
double free. Call amd_pmf_tee_deinit() inside the loop for each failed
iteration. Also on that path the error codes are not necessarily
negative kernel error codes. Set the error code to -EINVAL.
There is a very subtle third bug which is that if the call to
input_register_device() in amd_pmf_register_input_device() fails then
we call input_unregister_device() on an input device that wasn't
registered. This will lead to a reference counting underflow
because of the device_del(&dev->dev) in __input_unregister_device().
It's unlikely that anyone would ever hit this bug in real life.

phys_to_dma() sets the encryption bit on the translated DMA address. But
dma_to_phys() clears the encryption bit after it has been translated back
to the physical address, which could fail if the device uses DMA ranges.
AMD SME doesn't use the DMA ranges and thus this is harmless. But as we
are about to add support for other architectures, let us fix this.

Before the Commit 1f47ed294a2b ("block: cleanup and fix batch completion
adding conditions"), blk_mq_add_to_batch() did not add failed
passthrough requests to batch, and returned false. After the commit,
blk_mq_add_to_batch() always adds passthrough requests to batch
regardless of whether the request failed or not, and returns true. This
affected error logging feature in the NVME driver.
Before the commit, the call chain of failed passthrough request was as
follows:
nvme_handle_cqe()
blk_mq_add_to_batch() .. false is returned, then call nvme_pci_complete_rq()
nvme_pci_complete_rq()
nvme_complete_rq()
nvme_end_req()
nvme_log_err_passthru() .. error logging
__nvme_end_req() .. end of the rqeuest
After the commit, the call chain is as follows:
nvme_handle_cqe()
blk_mq_add_to_batch() .. true is returned, then set nvme_pci_complete_batch()
..
nvme_pci_complete_batch()
nvme_complete_batch()
nvme_complete_batch_req()
__nvme_end_req() .. end of the request, without error logging
To make the error logging feature work again for passthrough requests, move the
nvme_log_err_passthru() call from nvme_end_req() to __nvme_end_req().
While at it, move nvme_log_error() call for non-passthrough requests together
with nvme_log_err_passthru(). Even though the trigger commit does not affect
non-passthrough requests, move it together for code simplicity.

The current code calls arm_smmu_rpm_use_autosuspend() during device
attach, which seems unusual as it sets the autosuspend delay and the
'use_autosuspend' flag for the smmu device. These parameters can be
simply set once during the smmu probe and in order to avoid bouncing
rpm states, we can simply mark_last_busy() during a client dev attach
as discussed in [1].
Move the handling of arm_smmu_rpm_use_autosuspend() to the SMMU probe
and modify the arm_smmu_rpm_put() function to mark_last_busy() before
calling __pm_runtime_put_autosuspend(). Additionally,
s/pm_runtime_put_autosuspend/__pm_runtime_put_autosuspend/ to help with
the refactor of the pm_runtime_put_autosuspend() API [2].

Enable Quality of Service(QoS) support to speed up interrupt service
routine handle. Sometimes, a gic interrupt will be generated after
SPI transmission, but at this time the CPU is in an idle state and the
processing handler will be very slow. It takes time to exit the idle state
and then become active. This will cause the SPI handler to execute slowly
and cause SPI transfer timeouts.

Sometimes I get a NULL pointer dereference at boot time in kobject_get()
with the following call stack:
anatop_regulator_probe()
devm_regulator_register()
regulator_register()
regulator_resolve_supply()
kobject_get()
By placing some extra BUG_ON() statements I could verify that this is
raised because probing of the 'dummy' regulator driver is not completed
('dummy_regulator_rdev' is still NULL).
In the JTAG debugger I can see that dummy_regulator_probe() and
anatop_regulator_probe() can be run by different kernel threads
(kworker/u4:*). I haven't further investigated whether this can be
changed or if there are other possibilities to force synchronization
between these two probe routines. On the other hand I don't expect much
boot time penalty by probing the 'dummy' regulator synchronously.

In hindsight, there were some crucial subtleties overlooked when moving
{of,acpi}_dma_configure() to driver probe time to allow waiting for
IOMMU drivers with -EPROBE_DEFER, and these have become an
ever-increasing source of problems. The IOMMU API has some fundamental
assumptions that iommu_probe_device() is called for every device added
to the system, in the order in which they are added. Calling it in a
random order or not at all dependent on driver binding leads to
malformed groups, a potential lack of isolation for devices with no
driver, and all manner of unexpected concurrency and race conditions.
We've attempted to mitigate the latter with point-fix bodges like
iommu_probe_device_lock, but it's a losing battle and the time has come
to bite the bullet and address the true source of the problem instead.
The crux of the matter is that the firmware parsing actually serves two
distinct purposes; one is identifying the IOMMU instance associated with
a device so we can check its availability, the second is actually
telling that instance about the relevant firmware-provided data for the
device. However the latter also depends on the former, and at the time
there was no good place to defer and retry that separately from the
availability check we also wanted for client driver probe.
Nowadays, though, we have a proper notion of multiple IOMMU instances in
the core API itself, and each one gets a chance to probe its own devices
upon registration, so we can finally make that work as intended for
DT/IORT/VIOT platforms too. All we need is for iommu_probe_device() to
be able to run the iommu_fwspec machinery currently buried deep in the
wrong end of {of,acpi}_dma_configure(). Luckily it turns out to be
surprisingly straightforward to bootstrap this transformation by pretty
much just calling the same path twice. At client driver probe time,
dev->driver is obviously set; conversely at device_add(), or a
subsequent bus_iommu_probe(), any device waiting for an IOMMU really
should *not* have a driver already, so we can use that as a condition to
disambiguate the two cases, and avoid recursing back into the IOMMU core
at the wrong times.
Obviously this isn't the nicest thing, but for now it gives us a
functional baseline to then unpick the layers in between without many
more awkward cross-subsystem patches. There are some minor side-effects
like dma_range_map potentially being created earlier, and some debug
prints being repeated, but these aren't significantly detrimental. Let's
make things work first, then deal with making them nice.
With the basic flow finally in the right order again, the next step is
probably turning the bus->dma_configure paths inside-out, since all we
really need from bus code is its notion of which device and input ID(s)
to parse the common firmware properties with...

At the moment, if of_iommu_configure() allocates dev->iommu itself via
iommu_fwspec_init(), then suffers a DT parsing failure, it cleans up the
fwspec but leaves the empty dev_iommu hanging around. So far this is
benign (if a tiny bit wasteful), but we'd like to be able to reason
about dev->iommu having a consistent and unambiguous lifecycle. Thus
make sure that the of_iommu cleanup undoes precisely whatever it did.
