In kernel 5.11 the rkisp1 uapi had changed to support different hardware
revisions. Currently only revision 10 is supported by the rkisp1 IPA and
therefore 'init' should fail if the revision is not 10.
This changes depends on the kernel driver reporting the hardware
revision, and thus requires the rkisp1 driver from v5.11 or newer.

The IPA of rkisp1 relies on some of the camera's controls.
Therefore it can't work if those controls are not given.
Return -EINVAL from 'configure' in that case.
Also return error from the pipeline's 'configure' method
if the IPA configure fails.

According to the EXIF specification, the GPS method should be UNDEFINED,
and the first 8 bytes will designate the type. However, CTS expects the
first 8 bytes to be part of the data. Remove the 8-byte encoding

setRational was not working properly for EXIF tags in the GPS IFD due to
libexif not supporting those tags in exif_entry_initialize(). Manually
specify the size of the EXIF entry to fix this. While at it, add support
for setting multiple rationals, as that is a common use case for
rational EXIF tags.
As Rational types are no longer initialized by libexif directly, the
EXIF_TAG_{X,Y}_RESOLUTION exif tags will not have their default values
populated.

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.

Since commit 96aecfe36508 ("libcamera: camera_sensor: Use active area
size as resolution") the CameraSensor::resolution() method returned the
sensor's active pixel area size.
As the CameraSensor::resolution() method is widely used in the library
code base to retrieve the maximum frame size the sensor can produce,
in case it is smaller than the pixel area size the returned size cannot
be used to configure the sensor correctly.
Fix this by returning the maximum frame resolution the sensor can
produce, or the pixel area size in case the sensor embeds and ISP that
can upscale and the supported maximum frame size is thus larger that
the pixel array size.

Camera sensors can include an ISP. For instance, the AP1302 external ISP
can be connected to up to two raw camera sensors, and the combination of
the sensors and ISP is considered as a (smart) camera sensor from
libcamera's point of view.
The CameraSensor class has limited support for this already. Extend the
simple pipeline handler to support such sensors, by using the media
entity corresponding to the ISP instead of the raw camera sensor's
entity.
We don't need to handle the case where an entity in the SoC would expose
the MEDIA_ENT_F_PROC_VIDEO_ISP function, as pipeline containing an ISP
would have a dedicated pipeline handler.
The implementation is limited as it won't support other multi-entity
camera sensors (such as CCS). While this would be worth supporting, we
don't have a test platform with a CCS-compatible sensor at this point,
so let's not over-engineer the solution. Extending support to CCS (and
possibly other sensor topologies) will likely involve helpers that can
be used by other pipeline handlers (such as generic graph walk helpers
for instance) and extensions to the CameraSensor class.

When running with sensors that had no embedded data, the pipeline handler
would fill a dummy embedded data buffer with gain/exposure values, and
pass this buffer to the IPA together with the bayer buffer. The IPA would
extract these values for use in the controller algorithms.
Rework this logic entirely by having a new RPiCameraData::BayerFrame
queue to replace the existing bayer queue. In addition to storing the
FrameBuffer pointer, this also stores all the controls tracked by
DelayedControls for that frame in a ControlList. This includes include
exposure and gain values. On signalling RPi::IPA_EVENT_SIGNAL_ISP_PREPARE
IPA event, the pipeline handler now passes this ControlList from the
RPiCameraData::BayerFrame queue.
The IPA now extracts the gain and exposure values from the ControlList
instead of using RPiController::MdParserRPi to parse the embedded data
buffer.
