[libcamera-devel] [PATCH 00/23] Properties and compound controls

[Jacopo Mondi]

Hello,
   This series includes a few components I have separately sent in the previous
weeks:

- Support for libcamera properties and definition of location and rotation
- Support for compound controls with the introduction of Span<> class

The first part of the series defines the infrastructure to parse and generate
properties. Most of the patchs has already been reviewed, the biggest new
one is the 'rotation'  property definition, which I have already sent as
follow-up to my previouse series "[PATCH v4 00/10] Camera properties" which
is now superseded by this series.

The second half of the series adds support for compound controls, control that
can transport and arbitrary number of data elements.

Support for compound is realized with the introduction of a new Span<> class,
and later extended to the rest of the libcamera code base, including support
for serialization/deserialization in the last patches of the series.

A few patches not meant for inclusion added to test compound controls.

Thanks to Laurent off-line review effort I already squashed in some of the
proposed fixes and added his signed-off where opportune.

Thanks
   j
