The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).
This also fixes !CONFIG_OF error:

Since dvb_frontend_detach() is not called in ttusb_dec_exit_dvb(),
which is called when the device is disconnected, dvb_frontend_free()
is not finally called.
This causes a memory leak just by repeatedly plugging and
unplugging the device.
Fix this issue by adding dvb_frontend_detach() to ttusb_dec_exit_dvb().

The function of "dvb_ca_en50221_write_data" at source/drivers/media
/dvb-core/dvb_ca_en50221.c is used for two cases.
The first case is for writing APDU data in the function of
"dvb_ca_en50221_io_write" at source/drivers/media/dvb-core/
dvb_ca_en50221.c.
The second case is for writing the host link buf size on the
Command Register in the function of "dvb_ca_en50221_link_init"
at source/drivers/media/dvb-core/dvb_ca_en50221.c.
In the second case, there exists a bug like following.
In the function of the "dvb_ca_en50221_link_init",
after a TV host calculates the host link buf_size,
the TV host writes the calculated host link buf_size on the
Size Register.
Accroding to the en50221 Spec (the page 60 of
https://dvb.org/wp-content/uploads/2020/02/En50221.V1.pdf),
before this writing operation, the "SW(CMDREG_SW)" flag in the
Command Register should be set. We can see this setting operation
in the function of the "dvb_ca_en50221_link_init" like below.
...
if ((ret = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_SW)) != 0)
return ret;
...
But, after that, the real writing operation is implemented using
the function of the "dvb_ca_en50221_write_data" in the function of
"dvb_ca_en50221_link_init", and the "dvb_ca_en50221_write_data"
includes the function of "ca->pub->write_cam_control",
and the function of the "ca->pub->write_cam_control" in the
function of the "dvb_ca_en50221_wrte_data" does not include
"CMDREG_SW" flag like below.
...
if ((status = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_HC)) != 0)
...
In the above source code, we can see only the "IRQEN | CMDREG_HC",
but we cannot see the "CMDREG_SW".
The "CMDREG_SW" flag which was set in the function of the
"dvb_ca_en50221_link_init" was rollbacked by the follwoing function
of the "dvb_ca_en50221_write_data".
This is a bug. and this bug causes that the calculated host link buf_size
is not properly written in the CI module.
Through this patch, we fix this bug.

IRQ handler netup_spi_interrupt() takes spinlock spi->lock. The lock
is initialized in netup_spi_init(). However, irq handler is registered
before initializing the lock.
Spinlock dma->lock and i2c->lock suffer from the same problem.
Fix this by registering the irq at the end of probe.

When adding proper support for V4L2_FIELD_ALTERNATE it was missed that
this field format should trigger an interrupt for each field, not just
for the whole frame. Fix this by marking it as progressive in the
capture setup, which will then select the correct interrupt mode.
Tested on both Gen2 and Gen3 with the result of a doubling of the frame
rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is
now 50, which is expected for alternate field capture.

Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening in
the driver core in the quest to be able to move "struct bus" and "struct
class" into read-only memory, a task now complete with these changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules for
all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most of
them actually did so.
Other than those changes, included in here are a small set of other

- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes

devm_clk_get() will return either an error or NULL, which the driver
handles, continuing to use the clock of reading the value of the
clock-frequency property.
However, the value of ov5670->xvclk is left as-is and the other clock
framework functions aren't capable of handling error values.
Use devm_clk_get_optional() to obtain NULL instead of -ENOENT.

Add new ioctls to set and get subdev client capabilities. Client in this
context means the userspace application which opens the subdev device
node. The client capabilities are stored in the file handle of the
opened subdev device node, and the client must set the capabilities for
each opened subdev.
For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which
indicates that the client is streams-aware.
The reason for needing such a flag is as follows:
Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain
reserved fields (usually a single array field). These reserved fields
can be used to extend the ioctl. The userspace is required to zero the
reserved fields.
We recently added a new 'stream' field to many of these structs, and the
space for the field was taken from these reserved arrays. The assumption
was that these new 'stream' fields are always initialized to zero if the
userspace does not use them. This was a mistake, as, as mentioned above,
the userspace is required to zero the _reserved_ fields. In other words,
there is no requirement to zero this new stream field, and if the
userspace doesn't use the field (which is the case for all userspace
applications at the moment), the field may contain random data.
This shows that the way the reserved fields are defined in v4l2 is, in
my opinion, somewhat broken, but there is nothing to do about that.
To fix this issue we need a way for the userspace to tell the kernel
that the userspace has indeed set the 'stream' field, and it's fine for
the kernel to access it. This is achieved with the new ioctl, which the
userspace should usually use right after opening the subdev device node.

Structures passed to subdev pad operations are all zero-initialized when
declaring variables. In most cases, this is done with designated
initializers to initialize some of the fields to specific values, but in
a minority of cases the structures are zero-initialized by assigning
them to '{ 0 }' or '{ }'.
Improve coding style consistency by using designated initializers where
possible, always initializing the 'which' field.

Structures passed to subdev pad operations are all zero-initialized, but
not always with the same kind of code constructs. While most drivers
used designated initializers, which zero all the fields that are not
specified, when declaring variables, some use memset(). Those two
methods lead to the same end result, and, depending on compiler
optimizations, may even be completely equivalent, but they're not
consistent.
Improve coding style consistency by using designated initializers
instead of calling memset(). Where applicable, also move the variables
to inner scopes of for loops to ensure correct initialization in all
iterations.

Several drivers call subdev pad operations, passing structures that are
not fully zeroed. While the drivers initialize the fields they care
about explicitly, this results in reserved fields having uninitialized
values. Future kernel API changes that make use of those fields thus
risk breaking proper driver operation in ways that could be hard to
detect.
To avoid this, make the code more robust by zero-initializing all the
structures passed to subdev pad operation. Maintain a consistent coding
style by preferring designated initializers (which zero-initialize all
the fields that are not specified) over memset() where possible, and
make variable declarations local to inner scopes where applicable. One
notable exception to this rule is in the ipu3 driver, where a memset()
is needed as the structure is not a local variable but a function
parameter provided by the caller.
Not all fields of those structures can be initialized when declaring the
variables, as the values for those fields are computed later in the
code. Initialize the 'which' field in all cases, and other fields when
the variable declaration is so close to the v4l2_subdev_call() call that
it keeps all the context easily visible when reading the code, to avoid
hindering readability.

Commit 9593126dae ("media: venus: Add a handling of QC08C compressed
format") and commit cef92b14e6 ("media: venus: Add a handling of QC10C
compressed format") added support for the QC08C and QC10C compressed
formats respectively.
But these also caused a regression, because the new formats where added
at the beginning of the vdec_formats[] array and the vdec_inst_init()
function sets the default format output and capture using fixed indexes
of that array:
static void vdec_inst_init(struct venus_inst *inst)
{
...
inst->fmt_out = &vdec_formats[8];
inst->fmt_cap = &vdec_formats[0];
...
}
Since now V4L2_PIX_FMT_NV12 is not the first entry in the array anymore,
the default capture format is not set to that as it was done before.
Both commits changed the first index to keep inst->fmt_out default format
set to V4L2_PIX_FMT_H264, but did not update the latter to keep .fmt_out
default format set to V4L2_PIX_FMT_NV12.
Rather than updating the index to the current V4L2_PIX_FMT_NV12 position,
let's reorder the entries so that this format is the first entry again.
This would also make VIDIOC_ENUM_FMT report the V4L2_PIX_FMT_NV12 format
with an index 0 as it did before the QC08C and QC10C formats were added.

MIPI CCS uses a 16-bit MIPI manufacturer identifier for firmware filenames
compared to older 8-bit identifier used by SMIA. The requested firmware
files used the MIPI manufacturer ID even for SMIA compliant devices,
effectively making the manufacturer ID 0.
While CCS static data is a feature of CCS 1.1, it has no hardware
dependencies. Making this feature available for SMIA devices helps adding
support for them and avoids requesting ill-generated CCS static data file
names. The files are named as:
ccs/smiapp-module-vv-mmmm-rrrr.fw,
ccs/smiapp-sensor-vv-mmmm-rr.fw and
ccs/smia-sensor-vv-mmmm-rr.fw
where vv is the manufacturer ID, mmmm is the model ID and rr or rrrr is

The "rotation" fwnode device property is intended to allow specify the
sensor's physical mounting rotation, so that it can be exposed through
the read-only V4L2_CID_CAMERA_SENSOR_ROTATION control and applications
can decide how to compensate for that.
The imx258 driver has read-only VFLIP and HFLIP enabled, resulting in
a 180 degrees image rotation being produced by the sensor. But this
doesn't imply that the physical mounting rotation should match the
driver's implementation.
Now that the driver registers V4L2_CID_CAMERA_SENSOR_ROTATION
and V4L2_CID_HFLIP/VFLIP correctly, userspace has all the required
information to handle the rotation correctly, hence it is not necessary
to require the 'rotation' property to be fixed to 180 degrees in DTS.
