    "content": "To do actual lens dewarping, the dewarper will be configured based on\nthe tuning file. As a first step implement the basic loading of the\ntuning file and enable/disable the dewarper for the given camera based\non the existence of the \"Dewarp\" algorithm in the tuning file.\n\nTodo: This is an backwards incompatible change in that the dewarper is\ncurrently included in the chain unconditionally. Some users may want to\nnot use the dewarper, so it is sensible to make that configurable. If it\nshould be in the algorithms section or in a different one is open for\ndebate.\n\nSigned-off-by: Stefan Klug <stefan.klug@ideasonboard.com>\n\n---\n\nChanges in v2:\n- Drop unused params variable\n- Moved patch a bit earlier so canUseDewarper is available for handling\n  the orientation\n---\n src/ipa/libipa/module.h                  |  4 ++\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 48 +++++++++++++++++++++++-\n 2 files changed, 51 insertions(+), 1 deletion(-)",
