e96e9e6e1d pipeline: raspberrypi: Avoid over-allocation for ISP Output 1
The V4L2DeviceFormat structure for the ISP Output 1 node was a copy of what is
used ISP Output 0 node, but with the size changed. However, the plane size and
stride values were not updated. So there is a possibility that the buffer might
be over-sized for the requested resolution.

Fix this by only copying the relevant fields from the ISP Output 0
V4L2DeviceFormat structure, and let the device driver size the planes as needed.

54398c1583 libcamera: base: timer: Drop start() overload with int argument
The start(unsigned int msec) overload is error-prone, as the argument
unit can easily be mistaken in callers. Drop it and update all callers
to use the start(std::chrono::milliseconds) overload instead.

The callers now need to use std::chrono_literals. The using statement
could be added to timer.h for convenience, but "using" is discouraged in
header files to avoid namespace pollution. Update the callers instead,
and while at it, sort the "using" statements alphabetically in tests.

074fa98ac4 pipeline: rkisp1: Match sensor aspect ratio when generating configurations
The RkISP1Path::generateConfiguration() function limits the maximum
resolution to the sensor resolution, to avoid upscaling. It however
doesn't take the sensor aspect ratio into account, which leads to a
maximum (and default) resolution of 1920x1920 when using the self path
with a sensor that has a higher resolution.

Fix it by constraining the minimum and maximum resolutions to match the
sensor's aspect ratio.

c7d4599565 ipa: rkisp1: Replace event-based ops with dedicated functions
The IPARkISP1Interface currently uses event-type based structures in
order to communicate with the pipeline-handler (and vice-versa).
Replace the event based structures with dedicated functions associated
to each operation.

The translated naming scheme of operations to dedicated functions:
  ActionV4L2Set         => setSensorControls
  ActionParamFilled     => paramsBufferReady
  ActionMetadata        => metdataReady
  EventSignalStatBuffer => processStatsBuffer()
  EventQueueRequest     => queueRequest()

The lexical of IPARkISP1::metadataReady() will now conflict with the
metadataReady Signal being introduced in this patch as part of the
interface change. Hence, rename IPARkISP1::metadataReady() to
IPARkISP1::prepareReady() to prevent the conflict.

7653021549 libcamera: base: object: Prevent the same signal being connected more than once
Objects are not expected to be connected to the same signal more than
once. Doing so likely indicates a bug in the code, and can be
highlighted in debug builds with an assert that performs a lookup on the
signals_ list.

While it is possible to allow the implementation to let objects connect
to a specific signal multiple times, there are no expected use cases for
this in libcamera and this behaviour is restricted to favour defensive
programming by raising an error when this occurs.

Remove the support in the test framework which uses multiple Signal
connections on the same object, and update the test to use a second
Signal.

e96d02015c pipeline: raspberrypi: Fix the buffer count calculation for the ISP input stream
The ISP input stream currently only allocates a single slot in the
V4L2VideoDevice cache as it follows the number of buffers allocated for use.
However, this is wrong as the ISP input stream imports buffers from Unicam
image stream.  As a consequence of this, only one cache slot was used during
runtime for the ISP input stream, and if multiple buffers were to be queued
simultaneously, the queue operation would return a failure.

Fix this by passing the same number of RAW buffers available from the Unicam
image stream. Additionally, double this count in the cases where buffers could
be allocated externally from the application.

7f1e39e3e2 libcamera: camera_sensor: Clear camera flips after opening the device
We clear the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls immediately

this to be the case so that it can be relied upon.

Clearing the flips is harmless where sensor flips do not affect the
Bayer order.

This also fixes a bug in the Raspberry Pi pipeline handler where the
native Bayer order was being computed wrongly, but the new behaviour
here will be helpful to other pipeline handlers too. A subsequent
commit will tidy up the Raspberry Pi pipeline handler in this area as
it can now be simplified.

5e5eadabd8 libcamera: camera: Add validateColorSpaces to CameraConfiguration class
This function forces raw streams to have the "raw" color space, and
also optionally makes all non-raw output streams to share the same
color space as some platforms may require this.

When sharing color spaces we take the shared value to be the one from
the largest of these streams. This choice is ultimately arbitrary, but
can be appropriate if smaller output streams are used for image
analysis rather than human consumption, when the precise colours may
be less important.

c8a4b52e3a libcamera: v4l2_subdevice: Add colorSpace field to V4L2SubdeviceFormat
This adds a ColorSpace field to the V4L2SubdeviceFormat so that we can
set and request particular color spaces from V4L2.

This commit simply adds the field and fixes some occurrences of brace
initializers that would otherwise be broken. A subsequent commit will
pass and retrieve the value correctly to/from V4l2 itself.

e86aed6166 libcamera: video_device: Convert between ColorSpace class and V4L2 formats
Add functions to the V4L2Device class to convert to and from
libcamera ColorSpace.

These functions are added to the base V4L2Device class so that they can
be shared both by the video device class and subdevices.

With the ColorSpace class, the color space and related other fields
are stored together, corresponding to a number of fields in the
various different V4L2 format structures. Template functions are
therefore a convenient implementation, and we must explicitly
instantiate the templates that will be needed.

Note that unset color spaces are converted to requests for the
device's "default" color space.

The ColorSpace field is actually optional. If it is not set you will

7aef77130a libcamera: pipeline_handler: Prepare Request
Before queueing a request to the device, any synchronization fence from
the Request framebuffers has to be waited on.

Connect the Request::Private::prepared signal to the function that
queues requests to the hardware and call Request::Private::prepare().

When the waiting request queue is inspected, verify if it has completed its
preparation phase and queue it to the device.

3fb3c0d791 libcamera: request: Add Request::Private::prepare()
Add a prepare() function to the Private Request representation.

The prepare() function is used by the PipelineHandler class to
prepare a Request to be queued to the hardware.

The current implementation of prepare() handles the fences associated
with the Framebuffers part of a Request. The function starts an event
notifier for each of those and emits the Request::prepared signal when
all fences have been signalled or an optional timeout has expired.

The optional timeout allows to interrupt blocked waits and notify the
Request as failed so that it can be cancelled.

f6b6f15b54 libcamera: pipeline: Introduce stopDevice()
Since a queue of waiting Requests has been introduced, not all Requests
queued to the PipelineHandler are immediately queued to the device.

As a Camera can be stopped at any time, it is required to complete the
waiting requests after the ones queued to the device had been completed.

Introduce a pure virtual PipelineHandler::stopDevice() function to be
implemented by pipeline handlers and make the PipelineHandler::stop()
function call it before completing pending requests.
