The PCI_DEVICE_ID_NETRONOME_NFP6000_VF is available for use and
should be used instead of the PCI_DEVICE_NFP6000VF. Meanwhile,
PCI_DEVICE_NFP6000VF PCI ID is removed for not being used.

Multiple writes cause intermediate pointer values that do not
end on complete TX descriptors.
The QCP peripheral on the NFP provides a number of access
modes. In some access modes, the maximum amount to add must
be restricted to a 6bit value. The particular access mode
used by _nfp_qcp_ptr_add() has no such restrictions, so the
"< NFP_QCP_MAX_ADD" test is unnecessary.
Note that trying to add more that the configured ring size
in a single add will cause a QCP overflow, caught and handled
by the QCP peripheral.

alx_reinit has a lockdep assertion that the alx->mtx mutex must be held.
alx_reinit is called from two places: alx_reset and alx_change_mtu.
alx_reset does acquire alx->mtx before calling alx_reinit.
alx_change_mtu does not acquire this mutex, nor do its callers or any
path towards alx_change_mtu.
Acquire the mutex in alx_change_mtu.
The issue was introduced when the fine-grained locking was introduced
to the code to replace the RTNL. The same commit also introduced the
lockdep assertion.

The core clock and M2MC clocks are shared between some devices (Unicam
controllers and the HVS, and the HDMI controllers, respectively) that
will have various, varying, requirements depending on their current work
load.
Since those loads can require a fairly high clock rate in extreme
conditions (up to ~600MHz), we can end up running those clocks at their
maximum frequency even though we no longer require such a high rate.
Fortunately, those devices don't require an exact rate but a minimum
rate, and all the drivers are using clk_set_min_rate. Thus, we can just
rely on the fact that the clk_request minimum (which is the aggregated
minimum of all the clock users) is what we want at all times.

The M2MC clock provides the state machine clock for both HDMI
controllers.
However, if no HDMI monitor is plugged in at boot, its clock rate will
be left at 0 by the firmware and will make any register access end up in
a CPU stall, even though the clock was enabled.
We had some code in the HDMI controller to deal with this before, but it
makes more sense to have it in the clock driver. Move it there.

This has been do so far using some tests on the clock id in various
places, but this is fairly hard to extend and doesn't scale very well.

In order to reset the range on a clock, we need to call
clk_set_rate_range with a minimum of 0 and a maximum of ULONG_MAX. Since
it's fairly inconvenient, let's introduce a clk_drop_range() function
that will do just this.

When we change a clock minimum or maximum using clk_set_rate_range(),
clk_set_min_rate() or clk_set_max_rate(), the current code will only
trigger a new rate change if the rate is outside of the new boundaries.
However, a clock driver might want to always keep the clock rate to
one of its boundary, for example the minimum to keep the power
consumption as low as possible.
Since they don't always get called though, clock providers don't have the
opportunity to implement this behaviour.
Let's trigger a clk_set_rate() on the previous requested rate every time
clk_set_rate_range() is called. That way, providers that care about the
new boundaries have a chance to adjust the rate, while providers that
don't care about those new boundaries will return the same rate than
before, which will be ignored by clk_set_rate() and won't result in a
new rate change.

The code in clk_set_rate_range() will, if the current rate is outside of
the new range, force it to the minimum or maximum.
Since it's running under the condition that the rate is either lower
than the minimum, or higher than the maximum, this is equivalent to
using clamp, while being less readable. Let's switch to using clamp
instead.

The current core while setting the min and max rate properly in the
clk_request structure will not make sure that the requested rate is
within these boundaries, leaving it to each and every driver to make
sure it is.
It's not clear if this was on purpose or not, but this introduces some
inconsistencies within the API.
For example, a user setting a range and then calling clk_round_rate()
with a value outside of that range will get the same value back
(ignoring any driver adjustements), effectively ignoring the range that
was just set.
Another one, arguably worse, is that it also makes clk_round_rate() and
clk_set_rate() behave differently if there's a range and the rate being
used for both is outside that range. As we have seen, the rate will be
returned unchanged by clk_round_rate(), but clk_set_rate() will error
out returning -EINVAL.
Let's make sure the framework will always clamp the rate to the current
range found on the clock, which will fix both these inconsistencies.

If we were to have two users of the same clock, doing something like:
clk_set_rate_range(user1, 1000, 2000);
clk_set_rate_range(user2, 3000, 4000);
The second call would fail with -EINVAL, preventing from getting in a
situation where we end up with impossible limits.
However, this is never explicitly checked against and enforced, and
works by relying on an undocumented behaviour of clk_set_rate().
Indeed, on the first clk_set_rate_range will make sure the current clock
rate is within the new range, so it will be between 1000 and 2000Hz. On
the second clk_set_rate_range(), it will consider (rightfully), that our
current clock is outside of the 3000-4000Hz range, and will call
clk_core_set_rate_nolock() to set it to 3000Hz.
clk_core_set_rate_nolock() will then call clk_calc_new_rates() that will
eventually check that our rate 3000Hz rate is outside the min 3000Hz max
2000Hz range, will bail out, the error will propagate and we'll
eventually return -EINVAL.
This solely relies on the fact that clk_calc_new_rates(), and in
particular clk_core_determine_round_nolock(), won't modify the new rate
allowing the error to be reported. That assumption won't be true for all
drivers, and most importantly we'll break that assumption in a later
patch.
It can also be argued that we shouldn't even reach the point where we're
calling clk_core_set_rate_nolock().
Let's make an explicit check for disjoints range before we're doing
anything.

Any registered clk_core structure can have a NULL pointer in its dev
field. While never actually documented, this is evidenced by the wide
usage of clk_register and clk_hw_register with a NULL device pointer,
and the fact that the core of_clk_hw_register() function also passes a
NULL device pointer.
A call to clk_hw_get_clk() on a clk_hw struct whose clk_core is in that
case will result in a NULL pointer derefence when it calls dev_name() on
that NULL device pointer.
Add a test for this case and use NULL as the dev_id if the device
pointer is NULL.

The modem remoteproc on older Qualcomm SoCs (e.g. MSM8916 and MSM8974)
implements the BAM-DMUX protocol to allow access to the network data
channels of the modem. The hardware/firmware resources required to
implement the BAM-DMUX driver are described in an extra node in the
device tree (with the compatible "qcom,bam-dmux").
This node logically belongs below the modem remoteproc, so that both
control interfaces (rpmsg_wwan_ctrl) and network interfaces (bam_dmux)
have a common parent.
Unlike other child devices of the modem remoteproc, the bam-dmux device
currently does not follow the state of the remoteproc (i.e. it is not
added/removed when the remoteproc is started/stopped). However, this is
an implementation detail of the bam_dmux driver in Linux that might
change in the future.
To be flexible for future changes, create a standard platform device
specifically only for "qcom,bam-dmux", rather than populating all child
nodes. This is also more consistent with the way the other child nodes
are handled in the driver.
Note: of_platform_device_create() and of_node_put() have NULL-checks
internally, so there is no need to check if the "qcom,bam-dmux" node
actually exists in the device tree.

Block Aperture Window support was an attempt to layer an error model
over PMEM for platforms that did not support machine-check-recovery.
However, it was abandoned before it ever shipped, and only ever existed
in the ACPI specification. Meanwhile Linux has carried a large pile of
dead code for non-shipping infrastructure. For years it has been off to
the side out of the way, but now CXL and recent directions with DAX
support have the potential to collide with this code.
In preparation for adding discontiguous namespace support, a
pre-requisite for the nvdimm subsystem to replace device-mapper for
striping + concatenation use cases, delete BLK aperture support.
On the obscure chance that some hardware vendor shipped support for this
mode, note that the driver will still keep BLK space reserved in the
label area. So an end user in this case would still have the opportunity
to report the regression to get BLK-mode support restored without
risking the data they have on that device.

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worst scenario, could lead to heap overflows.
Also, address the following sparse warnings:

When CONFIG_PM is set but CONFIG_PM_SLEEP is not, two compiler warnings
appear:
drivers/i2c/busses/i2c-designware-platdrv.c:444:12: error: unused function 'dw_i2c_plat_suspend' [-Werror,-Wunused-function]
static int dw_i2c_plat_suspend(struct device *dev)

static int dw_i2c_plat_resume(struct device *dev)
^
2 errors generated.
These functions are only used in SET_LATE_SYSTEM_SLEEP_PM_OPS(), which
is defined as empty when CONFIG_PM_SLEEP is not defined. Mark the
functions as __maybe_unused to make it clear that these functions might
be unused in this configuration.

Since depending on the SoC or specific bus functionality some clocks
may be optional, we cannot get the benefit of using devm_clk_bulk_get()
but, by migrating to clk-bulk, we are able to remove the custom functions
mtk_i2c_clock_enable() and mtk_i2c_clock_disable(), increasing common
APIs usage, hence (lightly) decreasing kernel footprint.

* Timeouts are reported even in interrupt mode since commit
b3b8df97723d ("i2c: i801: Use wait_event_timeout to wait for
interrupts") so drop the comment which claims this only happens in
polled mode.
* xact does not include the PEC bit, as the driver does not support
software PEC.

Add support to the K3 DSP remoteproc driver to configure all the C66x
and C71x cores on J721E SoCs to be either in IPC-only mode or the
traditional remoteproc mode. The IPC-only mode expects that the remote
processors are already booted by the bootloader, and only perform the
minimum steps required to initialize and deinitialize the virtio IPC
transports. The remoteproc mode allows the kernel remoteproc driver to
do the regular load and boot and other device management operations for
a DSP.
The IPC-only mode for a DSP is detected and configured at driver probe
time by querying the System Firmware for the DSP power and reset state
and/or status and making sure that the DSP is indeed started by the
bootloaders, otherwise the device is configured for remoteproc mode.
Support for IPC-only mode is achieved through .attach(), .detach() and
.get_loaded_rsc_table() callback ops and zeroing out the regular rproc
ops .prepare(), .unprepare(), .start() and .stop(). The resource table
follows a design-by-contract approach and is expected to be at the base
of the DDR firmware region reserved for each remoteproc, it is mostly
expected to contain only the virtio device and trace resource entries.
NOTE:
The driver cannot configure a DSP core for remoteproc mode by any
means without rebooting the kernel if that DSP core has been started
by a bootloader. This is the current desired behavior and can be
enhanced in the future if the feature is needed.
