The recently introduced devm_v4l2_sensor_clk_get() helper aims at
simplifying sensor drivers by centralizing clock handling code, as well
as reducing cargo-cult and deprecated behaviour.
A set of drivers implement external clock handling in a non-standard
way. This can't be changed as there is a high risk of breaking existing
platforms, but keeping the code as-is creates a risk of new drivers
copying deprecated behaviour.
To fix this, introduce a new devm_v4l2_sensor_clk_get_legacy() helper
and use it in those driver. Compared to devm_v4l2_sensor_clk_get(), the
new helper takes the "clock-frequency" property into account and sets
the external clock rate on OF platforms, and adds the ability to specify
a fixed default or fallback clock rate in case the "clock-frequency"
property is not present.

ASPEED BMC IC has 2 different display engines. Please find AST2600's
datasheet to get detailed information.
1. VGA on PCIe
2. SoC Display (GFX)
By default, video engine (VE) will capture video from VGA. This patch
adds an option to capture video from GFX with standard ioctl,
vidioc_s_input.
An enum, aspeed_video_input, is added for this purpose.
enum aspeed_video_input {
VIDEO_INPUT_VGA = 0,
VIDEO_INPUT_GFX,
VIDEO_INPUT_MAX
};
To test this feature, you will need to enable GFX first. Please refer to
ASPEED's SDK_User_Guide, 6.3.x Soc Display driver, for more information.
In your application, you will need to use v4l2 ioctl, VIDIOC_S_INPUT, as
below to select before start streaming.
int rc;
struct v4l2_input input;
input.index = VIDEO_INPUT_GFX;
rc = ioctl(fd, VIDIOC_S_INPUT, &input);
if (rc < 0)
{

The output pixel interface is a parallel bus (32 bits), which
supports sending multiple pixels (1, 2 or 4) per clock cycle for
smaller pixel widths like RAW8-RAW16.
Dual-pixel and Quad-pixel modes can be a requirement if the export rate
of the Cadence IP in Single-pixel mode maxes out before the maximum
supported DPHY-RX frequency, which is the case with TI's integration of
this IP [1].
So, we export a function that lets the downstream hardware block request
a higher pixel-per-clock on a particular output pad.
We check if we can support the requested pixels per clock given the
known maximum for the currently configured format. If not, we set it
to the highest feasible value and return this value to the caller.

Introduce a helper for v4l2 sensor drivers on both DT- and ACPI-based
platforms to retrieve a reference to the clock producer from firmware.
This helper behaves the same as devm_clk_get() except where there is
no clock producer like in ACPI-based platforms.
For ACPI-based platforms the function will read the "clock-frequency"
ACPI _DSD property and register a fixed frequency clock with the frequency
indicated in the property.
This function also handles the special ACPI-based system case where:
. The clock-frequency _DSD property is present.
. A reference to the clock producer is present, where the clock is provided
by a camera sensor PMIC driver (e.g. int3472/tps68470.c)
In this case try to set the clock-frequency value to the provided clock.

Now that all drivers access the v4l2_fh from the file structure, there
is no need to pass it as an explicit argument to ioctl handlers. Set the
argument to NULL in the __video_do_ioctl() function, and rename the 'fh'
argument in the ioctl handler declarations to 'priv' indicate it does
not contain a file handle.
The argument could be removed altogether with a mechanical change
(probably using coccinelle), but there are plans to pass a new argument
to the ioctl handlers in the near future. The tree-wide change to remove
the argument, only to add another one soon after, would be too much
churn.

Accessing file->private_data manually to retrieve the v4l2_fh pointer is
error-prone, as the field is a void * and will happily convert
implicitly to any pointer type. To avoid direct access to
file->private_data, introduce a new inline function that retrieves the
v4l2_fh pointer, and use it to replace common access patterns through
the kernel.

Pull gpio updates from Bartosz Golaszewski:
"As discussed: there's a small commit that removes the legacy GPIO line
value setter callbacks as they're no longer used and a big, treewide
commit that renames the new ones to the old names across all GPIO
drivers at once.
While at it: there are also two fixes that I picked up over the course
of the merge window:
- remove unused, legacy GPIO line value setters from struct gpio_chip
- rename the new set callbacks back to the original names treewide
- fix interrupt handling in gpio-mlxbf2
- revert a buggy immutable irqchip conversion"

...
Define a new, optional, callback that allows the driver to
specify how the return data buffer is allocated. If that callback
is set, mailbox/pcc.c is now responsible for reading from and
writing to the PCC shared buffer.
This also allows for proper checks of the Commnand complete flag
between the PCC sender and receiver.
For Type 4 channels, initialize the command complete flag prior
to accepting messages.
Since the mailbox does not know what memory allocation scheme
to use for response messages, the client now has an optional
callback that allows it to allocate the buffer for a response
message.
When an outbound message is written to the buffer, the mailbox
checks for the flag indicating the client wants an tx complete
notification via IRQ. Upon receipt of the interrupt It will
pair it with the outgoing message. The expected use is to
free the kernel memory buffer for the previous outgoing message.

Currently elevators will record internal 'async_depth' to throttle
asynchronous requests, and they both calculate shallow_dpeth based on
sb->shift, with the respect that sb->shift is the available tags in one
word.
However, sb->shift is not the availbale tags in the last word, see
__map_depth:
if (index == sb->map_nr - 1)
return sb->depth - (index << sb->shift);
For consequence, if the last word is used, more tags can be get than
expected, for example, assume nr_requests=256 and there are four words,
in the worst case if user set nr_requests=32, then the first word is
the last word, and still use bits per word, which is 64, to calculate
async_depth is wrong.
One the ohter hand, due to cgroup qos, bfq can allow only one request
to be allocated, and set shallow_dpeth=1 will still allow the number
of words request to be allocated.
Fix this problems by using shallow_depth to the whole sbitmap instead
of per word, also change kyber, mq-deadline and bfq to follow this,
a new helper __map_depth_with_shallow() is introduced to calculate
available bits in each word.

This is a relatively small set of fixes and device quirks that came in
during the merge window, the AMD changes adding support for ACP 7.2
systems are all just adding IDs for the devices rather than any
substantial code - the actual code is the same as for prior versions of
the platform.

during the merge window, the AMD changes adding support for ACP 7.2
systems are all just adding IDs for the devices rather than any
substantial code - the actual code is the same as for prior versions of

This is mostly fixes and cleanups and code reworks that trickled in
across the merge window and the weeks leading up. The only
substantive update is the Mediatek ufs driver which accounts for the
bulk of the additions.

This was missed during the initial implementation. The VFIO PCI encodes
the vf_token inside the device name when opening the device from the group
FD, something like:
"0000:04:10.0 vf_token=bd8d9d2b-5a5f-4f5a-a211-f591514ba1f3"
This is used to control access to a VF unless there is co-ordination with
the owner of the PF.
Since we no longer have a device name in the cdev path, pass the token
directly through VFIO_DEVICE_BIND_IOMMUFD using an optional field
indicated by VFIO_DEVICE_BIND_FLAG_TOKEN.

Alienware calls this key "Performance Boost". Dell calls it "G-Mode".
The goal is to have a specific keycode to detect when this key is

In this round, we've mainly updated three parts: 1) folio conversion by Matthew,
2) switch to a new mount API by Hongbo and Eric, and 3) several sysfs entries
to tune GCs for ZUFS with finer granularity by Daeho. There are also patches
to address bugs and issues in the existing features such as GCs, file pinning,
write-while-dio-read, contingous block allocation, and memory access violations.
Enhancement:
- switch to new mount API and folio conversion
- add sysfs nodes to controle F2FS GCs for ZUFS
- improve performance on the nat entry cache
- drop inode from the donation list when the last file is closed
- avoid splitting bio when reading multiple pages
Bug fix:
- fix to trigger foreground gc during f2fs_map_blocks() in lfs mode
- make sure zoned device GC to use FG_GC in shortage of free section
- fix to calculate dirty data during has_not_enough_free_secs()
- fix to update upper_p in __get_secs_required() correctly
- wait for inflight dio completion, excluding pinned files read using dio
- don't break allocation when crossing contiguous sections
- vm_unmap_ram() may be called from an invalid context
- fix to avoid out-of-boundary access in dnode page
- fix to avoid panic in f2fs_evict_inode
- fix to avoid UAF in f2fs_sync_inode_meta()
- fix to use f2fs_is_valid_blkaddr_raw() in do_write_page()
- fix UAF of f2fs_inode_info in f2fs_free_dic
- fix to avoid invalid wait context issue
- fix bio memleak when committing super block
- handle nat.blkaddr corruption in f2fs_get_node_info()
In addition, there are also clean-ups and minor bug fixes.
