using of_node with of_fwnode_handle().

Filter out modes that have a clock rate greater than the max core clock
rate when adjusted for the perf clock factor
This is especially important for chipsets such as QCS615 that have lower
limits for the MDP max core clock.
Since the core CRTC clock is at least the mode clock (adjusted for the
perf clock factor) [1], the modes supported by the driver should be less
than the max core clock rate.

It turns out that the platform firmware on some models does not return
valid data when reading the bitmap of supported platform profiles.
This prevents the driver from loading on said models, even when the
platform profile interface itself works.
Fix this by stop using said bitmap until we have figured out how
the OEM software itself detects available platform profiles.

Add support for the Fn+P hotkey found on newer HP Victus (and probably
newer Omen) laptops. This hotkey is intended for use with Omen Gaming Hub
to change the performance profile (see [1]).
Pressing Fn+P under linux produced the following warning in dmesg:
> hp_wmi: Unknown event_id - 27 - 0x7
Implemented a handling for this event so that the hotkey cycles between the
platform profiles when triggered.
Tested on Victus 16-s1011nt (9Z791EA, MB 8C9C).
Changes in v2:
- Make the key just switches between platform profiles instead of
assigning a key event code.
- v1: https://lore.kernel.org/all/20250802213541.18791-2-edip@medip.dev/

asus_wmi_register_driver() may be called from multiple drivers
concurrently, which can lead to the racy list operations, eventually
corrupting the memory and hitting Oops on some ASUS machines.
Also, the error handling is missing, and it forgot to unregister ACPI
lps0 dev ops in the error case.
This patch covers those issues by introducing a simple mutex at
acpi_wmi_register_driver() & *_unregister_driver, and adding the
proper call of asus_s2idle_check_unregister() in the error path.

Handle LVDS pixel clock.
The LTDC operates with multiple clock domains for register access,
requiring all clocks to be provided during read/write operations. This
imposes a dependency between the LVDS and LTDC to access correctly all
LTDC registers. And because both IPs' pixel rates must be synchronized,
the LTDC has to handle the LVDS clock.

Change the 'ret' variable from unsigned int to int to store negative error
codes or zero returned by regmap_field_read() and regmap_read(), and change
'-1' to 'negative errno' in the comments.
Storing the negative error codes in unsigned type, doesn't cause an issue
at runtime but it's ugly as pants. Additionally, assigning negative error
codes to unsigned type may trigger a GCC warning when the -Wsign-conversion
flag is enabled.
No effect on runtime.

The pkey ioctl PKEY_CLR2SECK2 describes in the pkey.h header file
the parameter 'keygenflags' which is forwarded to the handler
functions which actually deal with the clear key to secure key
operation. The ep11 handler module function ep11_clr2keyblob()
function receives this parameter but does not forward it to the
underlying function ep11_unwrapkey() on invocation. So in the end
the user of this ioctl could not forward additional key generation
flags to the ep11 implementation and thus was unable to modify the
key generation process in any way. So now call ep11_unwrapkey()
with the real keygenflags instead of 0 and thus the user of this
ioctl can for example via keygenflags provide valid combinations
of XCP_BLOB_* flags.

When running test_stress_04.sh, the following warning is triggered:
WARNING: CPU: 1 PID: 135 at drivers/block/ublk_drv.c:1933 ublk_ch_release+0x423/0x4b0 [ublk_drv]
This happens when the daemon is abruptly killed:
- some references may still be held, because registering IO buffer
doesn't grab ublk char device reference
OR
- io->task_registered_buffers won't be cleared because io buffer is
released from non-daemon context
For zero-copy and auto buffer register modes, I/O reference crosses
syscalls, so IO reference may not be dropped naturally when ublk server is
killed abruptly. However, when releasing io_uring context, it is guaranteed
that the reference is dropped finally, see io_sqe_buffers_unregister() from
io_ring_ctx_free().
Fix this by adding ublk_drain_io_references() that:
- Waits for active I/O references dropped in async way by scheduling
work function, for avoiding ublk dev and io_uring file's release
dependency
- Reinitializes io->ref and io->task_registered_buffers to clean state
This ensures the reference count state is clean when ublk_queue_reinit()
is called, preventing the warning and potential use-after-free.

The MACDA TCAM can only be accessed by one entity at a time and as such we
cannot have simultaneous reads from the firmware to probe for changes from
the host. As such we have to send a message indicating what the state of
the MACDA is to the firmware when we updated it so that the firmware can
sync up the TCAMs it owns to route BMC packets to the host.
To support that we are adding a new message that is invoked when we write
the MACDA that will notify the firmware of updates from the host and allow
it to sync up the TCAM configuration to match the one on the host side.

The BMC itself can decide to abandon a link and move onto another link in
the event of things such as a link flap. As a result the driver may load
with the BMC not present, and then needs to update things to support the
BMC being present while the link is up and the NIC is passing traffic.
To support this we add support to the watchdog to reinitialize the RPC to
support adding the BMC unicast, multicast, and multicast promiscuous
filters while the link is up and the NIC owns the link.

In order for us to support the BMC possibly connecting, disconnecting, and
then reconnecting we need to be able to support entities outside of just
the NIC setting up promiscuous mode as the BMC can use a multicast
promiscuous setup.
To support that we should move the promisc_sync code out of the netdev and
into the RPC section of the driver so that it is reachable from more paths.

Having setup time 0 violates tAR, tCLR of some chips, for instance
TOSHIBA TC58NVG2S3ETAI0 cannot be detected successfully (first ID byte
being read duplicated, i.e. 98 98 dc 90 15 76 14 03 instead of
98 dc 90 15 76 ...).
Atmel Application Notes postulated 1 cycle NRD_SETUP without explanation
[1], but it looks more appropriate to just calculate setup time properly.

GD5F1GM9 supports a high-speed Continuous Read (CR) mode which allows
the entire memory array to be read out by a single read command
without re-issuing the 13h “Page Read to Cache” command for every page.
Datasheet summary
Feature register B0[3] (NR bit)
1 = Normal Read (default)
0 = Continuous Read (CR)
ECC status register 7Ch
Normal read: bits [3:0] → ECC status of last page
Continuous read: bits [7:4] → accumulated max bit-flips over the
whole sequential read operation.

bounds access of BAM arrays"), the {cmd,data}_sgl_nitems members in
the 'bam_transaction' structure are containing the number of elements
in the cmd/data scatter-gather lists.

while reinitializing the sg lists instead of recomputing the number of
elements to make it less error prone.
