It started as an itch I wanted to scratch,\nbeing bothered by the explicit Span construction in the Raspberry Pi IPA\nmodule.\n\nThe series starts with patch 1/4 that refactors the gen-controls.py\nscript to make it (hopefully) more readable, without any functional\nchange. Patch 2/4 then improves the YAML notation for variable-size\narray controls, and patch 3/4 extends the Control class to provide\naccess, at compilation time, to the control size in addition to its\ntype. The result is patch 4/4, which reverts usage of the explicit Span\nconstructor in the Rapsberry Pi IPA module.\n\nAs described in patch 3/4, this could be extended with the ability to\nperform runtime checks on control sizes, but that's an exercise I'll\nleave for later.\n\nLaurent Pinchart (4):\n utils: gen-controls: Factor out YAML data handling in classes\n utils: gen-controls: Improve YAML notation for variable-size array\n controls\n libcamera: controls: Store array control size in Control class\n ipa: raspberrypi: Remove unneeded Span casts\n\n include/libcamera/controls.h | 20 +--\n src/ipa/raspberrypi/raspberrypi.cpp | 19 ++-\n src/libcamera/control_ids.yaml | 2 +-\n src/libcamera/controls.cpp | 37 ++++--\n src/libcamera/property_ids.yaml | 4 +-\n utils/gen-controls.py | 195 +++++++++++++++++++++-------\n 6 files changed, 197 insertions(+), 80 deletions(-)\n\n\nbase-commit: e1ca213609abb99cc1b6e6f16214bf5a0936f3b7"}
