Ensure the controller switches to quad I/O mode when
spi-tx-bus-width dts property is 4 and the Quad SPI program
opcode (32h or 34h) is used. Without this change, high-bit
data will be lost during page programming.

Sometimes we may need to iterate over, or find an element in a read
only (or read mostly) red-black tree, and in that case we don't need a
mutable reference to the tree, which we'll however have to take to be
able to use the current (mutable) cursor implementation.
This patch adds a simple immutable cursor implementation to RBTree,
which enables us to use an immutable tree reference. The existing
(fully featured) cursor implementation is renamed to CursorMut,
while retaining its functionality.
The only existing user of the [mutable] cursor for RBTrees (binder) is
updated to match the changes.

accessing header
The driver expects to receive a struct gs_host_frame in
gs_usb_receive_bulk_callback().
Use struct_group to describe the header of the struct gs_host_frame and
check that we have at least received the header before accessing any
members of it.
To resubmit the URB, do not dereference the pointer chain
"dev->parent->hf_size_rx" but use "parent->hf_size_rx" instead. Since
"urb->context" contains "parent", it is always defined, while "dev" is not
defined if the URB it too short.

The driver lacks the cleanup of failed transfers of URBs. This reduces the
number of available URBs per error by 1. This leads to reduced performance
and ultimately to a complete stop of the transmission.
If the sending of a bulk URB fails do proper cleanup:
- increase netdev stats
- mark the echo_sbk as free
- free the driver's context and do accounting
- wake the send queue

Reading the interrupt register `SJA1000_IR` causes all of its bits to be
reset. If we ever reach the condition of handling more than
`SJA1000_MAX_IRQ` IRQs, we will have read the register and reset all its
bits but without actually handling the interrupt inside of the loop
body.
This may, among other issues, cause us to never `netif_wake_queue()`
again after a transmission interrupt.

The `kvaser_usb_leaf_wait_cmd()` and `kvaser_usb_leaf_read_bulk_callback`
functions contain logic to zero-length commands. These commands are used
to align data to the USB endpoint's wMaxPacketSize boundary.
The driver attempts to skip these placeholders by aligning the buffer
position `pos` to the next packet boundary using `round_up()` function.
However, if zero-length command is found exactly on a packet boundary
(i.e., `pos` is a multiple of wMaxPacketSize, including 0), `round_up`
function will return the unchanged value of `pos`. This prevents `pos`
to be increased, causing an infinite loop in the parsing logic.
This patch fixes this in the function by using `pos + 1` instead.
This ensures that even if `pos` is on a boundary, the calculation is
based on `pos + 1`, forcing `round_up()` to always return the next
aligned boundary.

static contents for each "service processor", whatever the fuck it is.
Congruent subdirectories of root, created at mount time, taken out
by kill_litter_super(). All dentries created with d_alloc_name() and are
left pinned. The odd part is that the list of service providers is
assumed to be unchanging - no locking, nothing to handle removals or
extra elements added later on.
... and it's a PCI device. If you ever tell it to remove an instance,
you are fucked - it doesn't bother with removing its directory from filesystem,
it has a strange check that presumably wanted to be a check for removed
devices, but it had never been fleshed out.
Anyway, d_add() -> d_make_persistent()+dput() in ibmasmfs_create_dir() and
ibmasmfs_create_file(), and make the latter return int - no need to even
borrow that dentry, callers completely ignore it.

Quite a bit is already done by infrastructure changes (simple_link(),
simple_unlink()) - all that is left is replacing d_instantiate() +
pinning dget() (in ->symlink() and ->mknod()) with d_make_persistent(),
and, in case of shmem, using simple_unlink() and simple_link() in
->unlink() and ->link() resp., instead of open-coding those there.
Since d_make_persistent() accepts (and hashes) unhashed ones, shmem
situation gets simpler - we no longer care whether ->lookup() has hashed
the sucker.
With that done, we don't need kill_litter_super() for these filesystems
anymore - by the umount time all remaining dentries will be marked
persistent and kill_litter_super() will boil down to call of
kill_anon_super().
The same goes for devtmpfs and rootfs - they are handled by
ramfs or by shmem, depending upon config.
NB: strictly speaking, both devtmpfs and rootfs ought to use
ramfs_kill_sb() if they end up using ramfs; that's a separate
story and the only impact of "just use kill_{litter,anon}_super()"
is that we fail to free their sb->s_fs_info... on reboot.
That's orthogonal to the changes in this series - kill_litter_super()
is identical to kill_anon_super() for those at this point.

Add support for pressure and temperature rising threshold events. For
both channels *_en and *_value (in raw units) attributes are exposed.
Since in write_event_config() the ctrl_reg1.active and ctrl_reg4
are modified, accessing the data->ctrl_reg{1,4} in set_trigger_state()
and write_event_config() needs to be now guarded by data->lock.
Otherwise, it would be possible that 2 concurrent threads executing
these functions would access the data->ctrl_reg{1,4} at the same time
and then one would overwrite the other's result.

dma_buf_unmap_attachment() in iio_buffer_dmabuf_release() with the
dma_buf_unmap_attachment_unlocked() helper.
This aligns with the standard DMA-BUF API, avoids duplicating
locking logic and eases future maintenance. No functional change.

clean up the mutex initialized in iio_device_alloc(). Ensure proper

Add support for Adreno 612 GPU found in SM6150/QCS615 chipsets.
A612 falls under ADRENO_6XX_GEN1 family and is a cut down version
of A615 GPU.
A612 has a new IP called Reduced Graphics Management Unit or RGMU
which is a small state machine which helps to toggle GX GDSC
(connected to CX rail) to implement IFPC feature. It doesn't support
any other features of a full fledged GMU like clock control, resource
voting to rpmh etc. So we need linux clock driver support like other
gmu-wrapper implementations to control gpu core clock and gpu GX gdsc.
This patch skips RGMU core initialization and act more like a
gmu-wrapper case.

The ADXL318 and ADXL319 are low noise density, low power, 3-axis
accelerometers based on ADXL380 and ADXL382, respectively. The main
difference between the new parts and the existing ones are the absence
of interrupts and events like tap detection, activity/inactivity, and
free-fall detection.
Other differences in the new parts are fewer power modes, basically
allowing only idle and measurement modes, and the removal of the 12-bit
SAR ADC path for the 3-axis signals (known as lower signal chain),
being excluisive for the temperature sensor in the ADXL318/319.

vm_op_enqueue() allocates an msm_vm_op struct with kmalloc,
but the return value is not checked for NULL value which
can be returned by kmalloc under low-memory conditions.
This can result in NULL pointer dereference when the pointer
is dereferenced.
Add NULL check after the allocation and propagate -ENOMEM back
to the caller in case of a failure.

If pm_runtime_put_sync() fails after watchdog_register_device()
succeeds, the probe function jumps to err_exit without
unregistering the watchdog device. This leaves the watchdog
registered in the subsystem while the driver fails to load,
resulting in a resource leak.
Add a new error label err_unregister_wdt to properly unregister
the watchdog device.

This driver adds support for the Renesas Window Watchdog Timer (WWDT).
Because it can only be setup once after boot and we cannot know if this
already happened in early boot stages, it is mandated that the firmware
configures the watchdog. Linux then adapts according to the given
setup. Note that this watchdog only reports an overflow to the Error
Control Module (ECM) and does not reset the SoC on its own.

Starting from the AST2600 platform, the SoC design has become more
complex, with an increased number of reset mask registers.
To support this, introduce a new field 'num_reset_masks' in the
'aspeed_wdt_config' structure to specify the number of reset mask
registers per platform. This change removes the need for hardcoded
platform-specific logic and improves scalability for future SoCs.

The VIA watchdog driver uses allocate_resource() to reserve a MMIO
region for the watchdog control register. However, the allocated
resource was not given a name, which causes the kernel resource tree
to contain an entry marked as "<BAD>" under /proc/iomem on x86
platforms.
During boot, this unnamed resource can lead to a critical hang because
subsequent resource lookups and conflict checks fail to handle the
invalid entry properly.

Pass in a PCI device to Spec::new(), and provide a Display
implementation for boot42, in order to provide a clear, concise report
of what happened: the driver read NV_PMC_BOOT42, and found that the GPU
is not supported.
For very old GPUs (older than Fermi), the driver still returns ENODEV,
but it does so without a driver-specific dmesg report. That is exactly
appropriate, because if such a GPU is installed, it can only be
supported by Nouveau. And if so, the user is not helped by additional
error messages from Nova.
Here's the full dmesg output for a Blackwell (not yet supported) GPU:
NovaCore 0000:01:00.0: Probe Nova Core GPU driver.
NovaCore 0000:01:00.0: Unsupported chipset: boot42 = 0x1b2a1000 (architecture 0x1b, implementation 0x2)

NVIDIA GPUs are moving away from using NV_PMC_BOOT_0 to contain
architecture and revision details, and will instead use NV_PMC_BOOT_42
in the future. NV_PMC_BOOT_0 will contain a specific set of values
that will mean "go read NV_PMC_BOOT_42 instead".
Change the selection logic in Nova so that it will claim Turing and
later GPUs. This will work for the foreseeable future, without any
further code changes here, because all NVIDIA GPUs are considered, from
the oldest supported on Linux (NV04), through the future GPUs.
Add some comment documentation to explain, chronologically, how boot0
and boot42 change with the GPU eras, and how that affects the selection
logic.
