Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.
Since the vb2_ops_wait_prepare/finish callbacks already rely on that field,
we can safely drop these callbacks.
This simplifies the code and this is a step towards the goal of deleting
these callbacks.

The vb2_thread is used for DVB support. This will queue and dequeue buffers
automatically.
It calls wait_finish/prepare around vb2_core_dqbuf() and vb2_core_qbuf(),
but that assumes all drivers have these ops set. But that will change
due to commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL").
So instead just check if the callback is available, and if not, use
q->lock, just as __vb2_wait_for_done_vb() does.

uvc_unregister_video() can be called asynchronously from
uvc_disconnect(). If the device is still streaming when that happens, a
plethora of race conditions can occur.
Make sure that the device has stopped streaming before exiting this
function.
If the user still holds handles to the driver's file descriptors, any
ioctl will return -ENODEV from the v4l2 core.
This change makes uvc more consistent with the rest of the v4l2 drivers
using the vb2_fop_* and vb2_ioctl_* helpers.
This driver (and many other usb drivers) always had this problem, but it
wasn't possible to easily fix this until the vb2_video_unregister_device()
helper was added. So the Fixes tag points to the creation of that helper.

Add a 'yuv' flag to the `rzg2l_cru_ip_format` structure to indicate
whether a given format is YUV-based and update the `rzg2l_cru_ip_formats`
array with this flag appropriately. This change enables a more efficient
way to check if the input and output formats use the same colorspace.
With this change, we can eliminate the use of `v4l2_format_info()` in
`rzg2l_cru_initialize_image_conv()` as the necessary details for the source
and destination formats are already available through the `yuv` flag.

Refactor the handling of supported formats in the RZ/G2L CRU driver by
adding `pixelformat` and `bpp` members to the `rzg2l_cru_ip_format`
structure.
New helper functions, `rzg2l_cru_ip_format_to_fmt()` and
`rzg2l_cru_ip_index_to_fmt()`, are added to retrieve format information
based on 4CC format and index, respectively. These helpers allow the
removal of the now redundant `rzg2l_cru_format_from_pixel()` function.
The new helpers are used in `rzg2l_cru_format_bytesperline()`,
`rzg2l_cru_format_align()`, and `rzg2l_cru_enum_fmt_vid_cap()`,
streamlining the handling of supported formats and improving code
maintainability.

`WARN_ON(!fmt)` check in `rzg2l_cru_format_bytesperline()` is unnecessary
because the `rzg2l_cru_format_align()` function ensures that a valid
`pixelformat` is set before calling `rzg2l_cru_format_bytesperline()`. As
a result, `rzg2l_cru_format_from_pixel()` is guaranteed to return a
non-NULL value, making the check redundant.
Additionally, the return type of `rzg2l_cru_format_bytesperline()` is
`u32`, but the code returned `-EINVAL`, a negative value. This mismatch is
now resolved by removing the invalid error return path.

The scope of the s_stream video operation is now fully supported by
{enable,disable}_streams. Explicitly document the s_stream() op as
deprecated and update the related documentation.

Move request_irq() to probe(), in order to avoid requesting IRQ during
device start which happens frequently. As this function is in probe(), it
is better to replace it with its devm variant for managing the resource
efficiently.
While at it, drop the IRQF_SHARED flag as currently there is a single user
for this IRQ.

If cci_read() fails, 'st' is set to 0 in cci_read(), so we return success,
instead of the expected error code.
Fix it and return the expected error.

Add support for Raspberry Pi CFE. The CFE is a hardware block that
contains:
- MIPI D-PHY
- MIPI CSI-2 receiver
- Front End ISP (FE)
The driver has been upported from the Raspberry Pi kernel commit
88a681df9623 ("ARM: dts: bcm2712-rpi: Add i2c<n>_pins labels").

Some R-Car SoCs are capable of capturing RAW10. Extend the format
enumeration, validation and setup to expose and configure for this
format if the particular device supports it.
The VIN is usually capable of converting from most media bus formats to
a range of different pixel formats. However if the input media bus
format is a RAW10 format this is not possible so the corresponding pixel
output format is forced.

Add the Gen4 family compatible. This will be used instead of a SoC
specific compatible for the new Gen4 SoC V4M. Two Gen4 boards (V3U and
V4H) have already been added prior and their bindings need to be kept
for backward compatibility.

The ISP Channel Selector IP is the same for all current Gen4 devices.
This was not known when adding support for V3U and V4H and a single SoC
specific compatible was used.
Before adding more SoC specific bindings for V4M add a family compatible
fallback for Gen4. That way the driver only needs to be updated once for
Gen4, and we still have the option to fix any problems in the driver if
any testable differences between the SoCs are found.
There are already DTS files using the V3U and V4H compatibles which
needs to be updated to not produce a warning for DTS checks. The driver
also needs to kept the compatible values to be backward compatible , but
for new Gen4 SoCs such as V4M we can avoid this.

The MAX96724 is almost identical to the MAX96712 and can be supported by
the same driver, add support for it.
For the staging driver which only supports patter generation the big
difference is that the datasheet (rev 4) for MAX96724 do not describe
the DEBUG_EXTRA register, which is at offset 0x0009 on MAX96712. It's
not clear if this register is removed or moved to a different offset.
What is known is writing to register 0x0009 have no effect on MAX96724.
This makes it impossible to increase the test pattern clock frequency
from 25 MHz to 75Mhz on MAX96724. To be able to get a stable test
pattern the DPLL frequency have to be increase instead to compensate for
this. The frequency selected is found by experimentation as the MAX96724
datasheet is much sparser then what's available for MAX96712.

The DEBUG_EXTRA register is not part of soon to be added MAX96724
device. To make it easier to understand the differences when reading the
code prepare for the addition by creating named defines for the
register.
