But that's for\nlater.\n\nThanks\n   j\n\nv4->v4:\n- Minor style and grammar fixes\n- [1/5]: Expand ControlInfoMap::validate() and ASSERT in the caller\n- Tested with CTS\n\nv2->v3:\n- Fix spelling in commit messages as suggested by Paul and collect tags\n\n- [1/5]:\n  - ControlInfoMap::validate()\n  - Rework ControlInfoMap documentation as suggested by Laurent\n\n- [2/5]:\n  - Moved test earlier and simplified code\n\n- [3/5]\n  - Drop 'enum class' and use Laurent's suggested naming\n  - Simplify de-serializer code that uses a localIdMap as suggested by Laurent\n\n- [4/5]\n  - Change IPAIPU3::init() prototype\n\n       init(libcamera.IPASettings settings,\n            libcamera.IPACameraSensorInfo sensorInfo,\n            libcamera.ControlInfoMap sensorControls)\n\n  - Move exposureTime_ initialization in PH back to initControls()\n\nv1->v2:\n- [1/5].
