The cci_update_bits() inside ov02c10_set_ctrl() can use the passed
data in the ctrl argument to access the vflip control value.
After changing this there is no need to store a pointer to the hflip
and vflip controls inside struct ov02c10, drop these.

The Dell XPS 13 9350 and XPS 16 9640 both have an upside-down mounted
OV02C10 sensor. This rotation of 180° is reported in neither the SSDB nor
the _PLD for the sensor (both report a rotation of 0°).
Add a DMI quirk mechanism for upside-down sensors and add 2 initial entries
to the DMI quirk list for these 2 laptops.
Note the OV02C10 driver was originally developed on a XPS 16 9640 which
resulted in inverted vflip + hflip settings making it look like the sensor
was upright on the XPS 16 9640 and upside down elsewhere this has been
fixed in commit d5ebe3f7d13d ("media: ov02c10: Fix default vertical flip").
This makes this commit a regression fix since now the video is upside down
on these Dell XPS models where it was not before.

During sensor calibration I noticed that with the hflip control set to
false/disabled the image was mirrored.
The horizontal flip control is inverted and needs to be set to 1 to not
flip. This is something which seems to be common with various recent
Omnivision sensors, the ov01a10 and ov08x40 also have an inverted
mirror control.
Invert the hflip control to fix the sensor mirroring by default.

bayer-pattern
The ov02c10 is capable of having its (crop) window shifted around with 1
pixel precision while streaming.
This allows changing the x/y window coordinates when changing flipping to
preserve the bayer-pattern.
__v4l2_ctrl_handler_setup() will now write the window coordinates at 0x3810
and 0x3812 so these can be dropped from sensor_1928x1092_30fps_setting.
Since the bayer-pattern is now unchanged, the V4L2_CTRL_FLAG_MODIFY_LAYOUT
flag can be dropped from the flip controls.
Note the original use of the V4L2_CTRL_FLAG_MODIFY_LAYOUT flag was
incomplete, besides setting the flag the driver should also have reported
a different mbus code when getting the source pad's format depending on
the hflip / vflip settings see the ov2680.c driver for example.

After commit d5ebe3f7d13d ("media: ov02c10: Fix default vertical flip")
the reported bayer-pattern of MEDIA_BUS_FMT_SGRBG10_1X10 is no longer
correct.
Change the 16-bit x-win register (0x3810) value from 2 to 1 so that
the sensor will generate data in GRBG bayer-order again.

The CRU version on the RZ/V2H SoC supports larger input sizes
(4096x4096) compared to the version on the RZ/G2L (2800x4095).
Store the per-SoC min/max sizes in the device match info and use them
in place of the hardcoded ones.
While at it, use the min sizes reported by the info structure to replace
the RZG2L_CSI2_DEFAULT_WIDTH/HEIGHT macros.

The Mali C55 driver uses the v4l2-isp framework, which performs
validation of the parameters buffer versioning in the
v4l2_isp_params_validate_buffer() function.
It is not necessary to replicate the validation of the parameters buffer
versioning in the platform-specific implementation.

Commit 6f504cbf108a ("media: convert media_request_alloc() to
FD_PREPARE()") moved the call to fd_install() (now hidden in
fd_publish()) before the snprintf(), making the later write to
potentially already freed memory, as userland is free to call
close() concurrently right after the call to fd_install() which
may end up in the request_fops.release() handler freeing 'req'.

declare and use module parameters. The rust_minimal sample module
demonstrates this, and the rust null block driver will be the first
to use it in the next cycle. This also adds the Rust module files
under the modules subsystem as agreed between the Rust and modules
maintainers.

- Add compile-time check for embedded NUL characters in MODULE_*()
macros. This module metadata was once used (and maybe still) to
bypass license enforcement (LWN article from 2003):

- Update some mis-typed allocations
These correct some accidentally wrong types used in allocations (that
didn't affect the resulting size) that never got picked up from the
batch I sent a few months ago.
- Enable GCC diagnostic context for value-tracking warnings
This results in better GCC diagnostics for the value range tracking,
so we can get better visibility into where those values are coming
from when we get out-of-bounds warnings at compile time.

Pull fd prepare updates from Christian Brauner:
"This adds the FD_ADD() and FD_PREPARE() primitive. They simplify the
common pattern of get_unused_fd_flags() + create file + fd_install()
that is used extensively throughout the kernel and currently requires
cumbersome cleanup paths.
FD_ADD() - For simple cases where a file is installed immediately:
fd = FD_ADD(O_CLOEXEC, vfio_device_open_file(device));
if (fd < 0)
vfio_device_put_registration(device);
return fd;
FD_PREPARE() - For cases requiring access to the fd or file, or
additional work before publishing:
FD_PREPARE(fdf, O_CLOEXEC, sync_file->file);
if (fdf.err) {
fput(sync_file->file);
return fdf.err;
}
data.fence = fd_prepare_fd(fdf);
if (copy_to_user((void __user *)arg, &data, sizeof(data)))
return -EFAULT;
return fd_publish(fdf);
The primitives are centered around struct fd_prepare. FD_PREPARE()
encapsulates all allocation and cleanup logic and must be followed by
a call to fd_publish() which associates the fd with the file and
installs it into the caller's fdtable. If fd_publish() isn't called,
both are deallocated automatically. FD_ADD() is a shorthand that does
fd_publish() immediately and never exposes the struct to the caller.
I've implemented this in a way that it's compatible with the cleanup
infrastructure while also being usable separately. IOW, it's centered
around struct fd_prepare which is aliased to class_fd_prepare_t and so
we can make use of all the basica guard infrastructure"

In preparation for making the kmalloc family of allocators type aware,
we need to make sure that the returned type from the allocation matches
the type of the variable being assigned. (Before, the allocator would
always return "void *", which can be implicitly cast to any pointer type.)
The assigned type is "struct iris_inst *", but the returned type is
"struct iris_inst_hfi_gen2 *". The allocation is intentionally larger as
the first member of struct iris_inst_hfi_gen2 is struct iris_inst, so
this is by design. Cast the allocation type to match the assignment.

Add a driver for Arm's Mali-C55 Image Signal Processor. The driver is
V4L2 and Media Controller compliant and creates subdevices to manage
the ISP itself, its internal test pattern generator as well as the
crop, scaler and output format functionality for each of its two
output devices.

Add to the V4L2 framework helper functions to support drivers when
validating a buffer of V4L2 ISP parameters.
Driver shall use v4l2_isp_params_validate_buffer_size() to verify the
size correctness of the data received from userspace, and after having
copied the data to a kernel-only memory location, complete the
validation by calling v4l2_isp_params_validate_buffer().

Add a v4l2 sub-device driver for the Sony IMX111 image sensor. This is a
camera sensor using the i2c bus for control and the csi-2 bus for data.
The following features are supported:
- manual exposure, digital and analog gain control support
- pixel rate/link freq control support
- supported resolution up to 3280x2464 for single shot capture
- supported resolution up to 1920x1080 @ 30fps for video
- supported bayer order output SGBRG10 and SGBRG8
Camera module seems to be partially compatible with Nokia SMIA but it
lacks a few registers required for clock calculations and has different
vendor-specific per-mode configurations which makes it incompatible with
existing CCS driver.

Smatch is confused by the control initialization logic. It assumes that
there can be a case where imx214->link_freq can be NULL and ctrls_init
returns 0.
Re-arrange the function to make smatch happy.
This patch fixes this smatch error:

Sometimes, users will not use all of the MIPI CSI 2 lanes available when
connecting to the MIPI CSI receiver of their device. Add a helper
function that checks the mbus_config for the device driver to allow
users to define the number of active data lanes through the
get_mbus_config op.
If the driver does not implement this op, fall back to using the maximum
number of lanes available.

Introduce 2x2 binning mode (1312x972@60fps). Since there are multiple
modes now, use v4l2_find_nearest_size() to select the appropriate mode
in .set_fmt().
For 2x2 binning the minimum shutter value supported is 17 instead of 9.
This effects the maximum allowed exposure time, and if not enforced then
the sensor produces very dark frames when the minimum shutter limit is
violated.
Lastly, update the crop size reported to the userspace. When trying 2x2
binning with the datasheet suggested pixel array size (i.e. 2592 / 2 =>
1296), on some platforms (Raspberry Pi 5) artefacts are introduced on
the right edge of the output image. Instead, using a higher width of
1312 works fine on all platforms.

While switching modes, updating to a different value of HBLANK isn't
sufficient, as this is a read-only control with a single allowed value,
and thus hblank_min == hblank_max == hblank of the default mode.
So to correctly update the user-facing value of the HBLANK parameter,
which is necessary for correct framerate calculation, update the whole
range when switching modes.

to the readout direction (normal/inverted) as mentioned in the

Since the register IMX335_REG_AREA3_ST_ADR_1 is based on the
flip (and is set via vflip related registers), it has been
moved out of the 2592x1944 mode regs.
