This version is enough to\nhandle the new sensors that I'm looking at, though I expect there's\nstill some more discussion to go!\n\nThe commit message explains most of it, I think. The sensor in\nquestion has a few other quirks, to be addressed later, but this will\nbe enough to allow image statistics to be read from the sensor\nmetadata and used in place of the usual ISP-generated ones. It will\nalso support other sensors that are generating interesting metadata.\n\nThanks!\n\nDavid\n\nDavid Plowman (1):\n ipa: raspberrypi: Use CamHelpers to generalise sensor metadata parsing\n\n src/ipa/raspberrypi/cam_helper.cpp | 44 +++++++++++++++\n src/ipa/raspberrypi/cam_helper.hpp | 11 +++-\n src/ipa/raspberrypi/raspberrypi.cpp | 83 ++++++++++-------------------\n 3 files changed, 83 insertions(+), 55 deletions(-)"}
