[libcamera-devel] [PATCH v3 04/23] libcamera: control_serializer: Support internal controls

[Jacopo Mondi]

The control serializer class uses tags to identify which ControlIdMap
to use to de-serialize a ControlList.

Add a value for internal controls to the ipa_controls_id_map_type
enumeration and use it to identify lists of internal controls.
