Update the imx477 CamHelper to use long exposure modes if needed.
This is done by overloading the CamHelper::GetVBlanking function to return a
frame length (and vblank value) computed using a scaling factor when the value
would be larger than what the sensor register could otherwise hold.
CamHelperImx477::Prepare is also overloaded to ensure that the "device.status"
metadata returns the right value if the long exposure scaling factor is used.
The scaling factor is unfortunately not returned back in metadata.
With the current imx477 driver, we can achieve a maximum exposure time of approx
127 seconds since the HBLANK control is read-only.

Store the frame length into the DeviceStatus struct. The value is extracted
from embedded data when available, or calculated from the VBLANK value passed
from DelayedControls otherwise.
Update imx477 and imx219 CamHelper classes to extract the frame length from the
embedded data buffer.

Instead of having each CamHelper subclass the MdParserSmia, change the
implementation of MdParserSmia to be more generic. The MdParserSmia now gets
given a list of registers to search for and helper functions are used to compute
exposure lines and gain codes from these registers.
Update the imx219 and imx477 CamHelpers by using this new mechanism.

should include base/private.h.
Any interface which includes the private.h header will only be able to
build if the libcamera_private dependency is used (or the
libcamera_base_private dependency directly).
Build targets which are intended to use the private API's will use the
libcamera_private to handle the automatic definition of the inclusion

- Message
- Object
- Signal
- Semaphore

CameraSensorInfo structure is designed to pass in camera sensor related
information from pipeline-handler to IPA. Since the pipeline-handler
and IPA are connected via mojom IPC IPA interface, the interface
itself provides a more suitable placement of CameraSensorInfo,
instead of camera_sensor.h (which is a libcamera internal header
ultimately, at this point).
As CameraSensorInfo is already defined in core.mojom, it is just
a matter of removing [skipHeader] tag to allow code-generation
of CameraSensorInfo.
Finally, update header paths to include CameraSensorInfo definition
from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

The controller algorithms currently run on every frame provided to the
IPA by the pipeline handler. This may be undesirable for very fast fps
operating modes where it could significantly increase the computation
cycles (per unit time) without providing any significant changes to the
IQ parameters. The added latencies could also cause dropped frames.
Pass the FrameBuffer timestamp to the IPA through the controls. This
timestamp will be used to rate-limit the controller algorithms to run
with a minimum inter-frame time given by a compile time constant,
currently set to 16.66ms. On startup, we don't rate-limit the algorithms
until after the number of frames required for convergence.

CamHelpers get virtual Prepare() and Process() methods, running just
before and just after the ISP, just like Raspberry Pi Algorithms.
The Prepare() method is able to parse the register dumps in embedded
data buffers, and can be specialised to perform custom processing when
necessary.
The IPA itself only needs to call the new Prepare() and Process()
methods. It must fill in the DeviceStatus from the controls first, in
case the Prepare() method does not supply its own values.

imx290 and imx327 share the same kernel driver (imx290.c) and are
therefore both recognised here as "imx290". We add the necessary
CamHelper for these sensors, as well as a camera tuning file.
The tuning was done with an Innomaker STARVIS IMX327LQR module. These
have no IR cut filter so there is no proper colour tuning. However,
you should obtain reasonable results for most modules using this
sensor. Specific tunings for further modules can always be added
subsequently.
To use this sensor on the Raspberry Pi platform, please add
dtoverlay=imx290,clock-frequency=74250000
into your /boot/config.txt file.
