[libcamera-devel] [PATCH 0/3] libcamera: pipeline handlers: Fail if roles are not supported

[Jacopo Mondi]

The Camera API prescribes that if the list of roles supplied to
generateConfiguration() is not supported, the function shall fail.

All pipeline handlers but the IPU3 do not comply with the specification,
silently adjusting the generated configuration to their capabilities.

Fix this by failing explicitly if the provided list of roles cannot be
satisfied.

This small series prepares to rework the IPU3 generate configuration function,
which will be aligned to the implementation found in other pipeline handlers
(more spcifically to the raspberry pi one, which has similar constraints on the
number of supported output streams)

Thanks
