Remove the restriction on using the '/' character in the IPA name
string. This allows more flexibility in IPA directory structures where
different IPA modules might live in subdirectories under the usual
src/ipa/<platform>/ top level directory.

The STM32 contains a camera pipeline known as the DCMIPP (Digital
Camera-Memory Interface Pixel Processor) which receives data from a
parallel interface and dumps the post-processed data to memory. The
pipeline is capable of some processing in the form of downscaling
captured data through cropping or skipping the sensor's output.
The simple pipeline handler is quite capable of handling the DCMIPP
given its operation is handled entirely through configuring the pads
of a media graph, so add support for the driver to the pipeline's
supportedDevices array.

Just like we do for other pipeline handlers already.
This ensures we corretly pass on transforms that are not handled by the
sensor - e.g. rotations - back to the app via the config, which is
required on devices like the Pinephone.

At generateConfiguration() a YUV/RGB pixel format is preferred for the
StillCapture/VideoRecording/Viewfinder roles, but currently there are no
guarantees in place that the sensor provides a non-Bayer bus format from
which YUV/RGB can be generated.
This makes the default configuration generated for those roles not to
work if the sensor is a RAW-only one.
To improve the situation split the configuration generation in two,
one for YUV modes and one for Raw Bayer mode.
StreamRoles assigned to a YUV mode will try to first generate a YUV
configuration and then fallback to RAW if that's what the sensor can
provide.
As an additional requirement, for YUV streams, the generated mode has to
be validated with the sensor to confirm the desired sizes can be
generated as the ISI cannot up-scale. In order to test a format use the
newly introduced CameraSensor::tryFormat().

The ISICameraConfiguration::validate() function selects which media

of the first configured stream using the media bus code associated to it
in the formatsMap_ map.
In order to remove the PixelFormamt-to-mbus-code association in

As per the RAW format selection, the media bus format selection
procedure relies on the direct association of PixelFormat and media
bus code in the formatsMap_ map.
As the ISI can generate YUV and RGB formats from any non-Bayer media
bus format, break out the YUV/RGB media bus format selection to a
separate function.
The newly introduced getYuvMediaBusFormat() tests a list of
known-supported media bus formats against the list of media bus
formats supported by the sensor and tries to prefer media bus
codes with the same encoding as the requested PixelFormat.
Use the newly introduced function in
ISICameraConfiguration::validateYuv() to make sure the sensor can
produce a YUV/RGB media bus format.

The current implementation of the ISI pipeline handler handles
translation of PixelFormat to media bus formats from the sensor
through a centralized map.
As the criteria to select the correct media bus code depends on if the
output PixelFormat is a RAW Bayer format or not, start by splitting
the RAW media bus code procedure selection out by adding a function
for such purpose to the ISICameraData class.
Add the function to the ISICameraData and not to the
ISICameraConfiguration because:
- The sensor is a property of CameraData
- The same function will be re-used by the ISIPipelineHandler
during CameraConfiguration generation.

It's possible to construct a Camera with an unsafe controlInfo_.
This is the case in the Simple pipeline, where the camera controls are
not populated.
With Simple, if we attempt to set a Control, we end up with a segfault
because the default constructor for ControlInfoMap doesn't
intialized idmap_ which is initialized at class declaration time as
const ControlIdMap *idmap_ = nullptr;
Add some safeguards in ControlInfoMap to handle this case.

In `udevNotify()`, constructing an std::string from the device's
associated action is unnecessary as it is only compared against static
strings, and for that purpose an std::string_view works just as well,
while being cheaper to construct.
In the same vein, an std::string_view can be used to store the device's
devnode initially, and the string construction can be deferred until it
is needed.
Furthermore, previously `udev_device_get_devnode()` was called twice.
The extra call is now removed.

remove the `MediaDeviceDeps` object from the `pending_` list, which
would result in it being destroyed. However, there would still be

in the pipeline handlers due to unexpected request state.
If the status has not been reset to Request::RequestPending, it is
either not new, or has not been correctly procesed through

We could check both pointer validity and converter validity in the

the converter validity in the create() function and return a null
pointer when no valid converter is found.

On Raspberry Pi Compute Module platforms, it is possible to attach a
single camera device only to the secondary Unicam port. The current
logic of PipelineHandlerRPi::match() will return a failure during
enumeration of the first Unicam media device (due to no sensor attached,
or sensor failure) and thus the second Unicam media device will never be
enumerated.
Fix this by looping over all Unicam instances in PipelineHandlerRPi::match()
until a camera is correctly registered, or return a failure otherwise.

Add a new parameter to the pipeline handler config file named
"unicam_timeout_value_ms" to allow users to override the automatically
computed Unicam timeout value.
This value is given in milliseconds, and setting a value of 0 (the
default value) disables the override.
An example use of this parameter would be if an application configured a
RAW stream, and provides buffers for the stream on every request. If the
application holds off on sending requests for a particular reason (e.g.
a timelapse use case), then we will possibly hit the watchdog timeout as
it is only a small multiple of the frame length. This override allows an
application to select a larger value with the knowledge that it may
space requests longer than the calculated timeout value.

createPipelineHandlers
Currently the function `createPipelineHandlers` connects itself to the
`devicesAdded` signal at the end of each call. As the Signal object
supports multiple non-unique listeners connected to it, the former
function would be called exponentially often with each new emitted event
on `devicesAdded` (i.e. with udev plugging in a new camera)
Fix it by connecting the createPipelineHandlers() slot to `devicesAdded`
signal in CameraManager::Private::init() instead. This will prevent the
slot getting connected multiple times to the `devicesAdded` signal.

in the pipeline handler. Pass this result to the IPA on init.

Previously the x,y offsets in the min/max ScalerCrop control values
were zero. Here we make them the same as the sensor's analogue crop
offset which is I think less misleading.
With this change, it also seems reasonable to advertise the default
scaler crop value to be the true default that you will get. This makes
it possible for applications to see what that value will be without
having to start the camera and wait for frames.

Add support for Transform to the RkISP1 pipeline handler.
The pipeline rotates using the sensor's V/H flips, hence use the
CameraSensor helpers to handle transformation requests from
applications.

Augment the CameraSensor::setFormat() function to configure horizontal
and vertical flips before applying the image format on the sensor.
Applying flips before format is crucial as they might change the Bayer
pattern ordering.
To allow users of the CameraSensor class to specify a Transform,
add to the V4L2SubdeviceFormat class a 'transform' member, by
default initialized to Transform::Identity.
Moving the handling of H/V flips to the CameraSensor class allows to
remove quite some boilerplate code from the IPU3 and RaspberryPi
pipeline handlers.
No functional changes intended.

The two pipeline handlers that currently support Transform (IPU3 and
RaspberryPi) implement it by operating H/V flips on the image sensor.
Centralize the code that validates a Transform request against the
sensor rotation capabilities in the CameraSensor class.
The implementation in the IPU3 pipeline handler was copied from the
RaspberryPi implementation, and is now centralized in CameraSensor to
make it easier for other platforms.
The CameraSensor::validateTransform() implementation comes directly from
the RaspberryPi pipeline handler, no functional changes intended.

During the camera sensor driver validation, verify if the sensor
supports horizontal and vertical flips and store a flag as
CameraSensor::supportFlips_ class member.
The flag will be later inspected when applying flips.

Support for the OmniVision OV8858 sensor is scheduled for inclusion in
the Linux kernel in version v6.3.
Add support for the sensor in libcamera by providing static properties
and a camera sensor helper in libipa.
The camera sensor helper expresses analogue gain increments in 1/128
step which differs from what is reported in the sensor documentation in
section "5.8 manual exposure compensation/ manual gain compensation" [0]
A more detailed analysis of the sensor gain model is reported at:
https://patchwork.linuxtv.org/project/linux-media/patch/20221106171129.166892-2-nicholas@rothemail.net/#142267
Record with a \todo note a reference to discussion on the gain model
implementation.
