Hi Niklas,

Thank you for the patch.

For open-source IPAs that are shipped with libcamera this is fine, but
third-party IPAs, open-source or closed-source, won't have access to
internal headers.

For the open-source IPAs this isn't a blocker, but should still be
addressed sooner than later. For the closed-source IPAs, I notice you
include v4l2_controls.h in ipa_interface.h, and that's a problem as it
requires linking against libcamera. I would like to discuss how to solve
this issue. In the meantime,
