2bc657f47b libcamera: v4l2_pixelformat: Move DRM/V4L2 format conversion
Move the DRM/V4L2 format conversion code from V4L2VideoDevice to
V4L2PixelFormat. This is a more natural home for the code.

fd554f9dba libcamera: ipa: Add support for CameraSensorInfo
Add support for camera sensor information in the libcamera IPA protocol.

Define a new 'struct ipa_sensor_info' structure in the IPA context and
use it to perform translation between the C and the C++ API.

Update the IPAInterface::configure() operation to accept a new
CameraSensorInfo parameter and port all users of that function to
the new interface.

Verify that the sensor model matches the expected value. The whole model
extraction heuristic isn't fully tested as that would require being able

79ab0e925a libcamera: v4l2_device: Simplify usage of getControls()
The V4L2Device::getControls() function takes a ControlList that needs to
be pre-populated with dummy entries for the controls that need to be
read. This is a cumbersome API, especially when reading a single
control. Make it nicer by passing the list of V4L2 controls as a vector
of control IDs, and returning a ControlList.

256d0a4098 test: Use float values for brightness, contrast and saturation
Two tests use the brightness, contrast and saturation controls with
integer failures. They were not updated by commit eff4b1aa01 which
turned those controls into floats. This doesn't cause test failures as
the control API converts the value types. For correctness, update the
tests to use float values.

With the FrameBuffer interface the V4L2 buffer indexes are not visible
outside the V4L2VideoDevice so it's not possible to to test that the
expected indexes are used when using external buffers (allocated
directly from a V4L2 video device) with a Camera. Rewrite the test to
this limitation.

The idea of the test stays the same, test that buffers allocated from a
V4L2 video device (vivid) can be imported and used on a Camera (vimc).
As an added bonus the rewrite makes use of the FrameBuffer interface for
the allocation of buffers at the source (vivid) and imports them to the
Camera which still uses the Buffer interface internally.
