    "content": "Hi,\n\nHere is an attempt at switching all time based variables in our IPA/Controller\nto use std::chrono::duration.  This change makes things much less error prone\nwhen converting time bases or performing arithmetic on various time based\nvariables.  It also makes things quite neat when defining time duration defaults.\n\nPatch 1 provides some simple helpers for using std::chrono::duration.  Patches\n2-4 do the conversion in stages.  Because of the nature of this conversion,\nsome of the changes in earlier patches get reverted back once all the conversions\nhave been completed.\n\nThanks,\nNaush\n\nNaushir Patuck (4):\n  ipa: raspberrypi: Add helper macros for std::chrono::duration\n  ipa: raspberrypi: Switch ipa/cam_helper to use RPiController::Duration\n  ipa: raspberrypi: Switch AgcAlgorithm API to use\n    RPiController::Duration\n  ipa: raspberrypi: Switch the AGC/Lux code to use\n    RPiController::Duration\n\n src/ipa/raspberrypi/cam_helper.cpp            | 17 ++--\n src/ipa/raspberrypi/cam_helper.hpp            | 10 ++-\n .../raspberrypi/controller/agc_algorithm.hpp  |  7 +-\n src/ipa/raspberrypi/controller/agc_status.h   | 12 +--\n src/ipa/raspberrypi/controller/camera_mode.h  |  5 +-\n .../raspberrypi/controller/device_status.h    |  6 +-\n src/ipa/raspberrypi/controller/duration.hpp   | 33 +++++++\n src/ipa/raspberrypi/controller/rpi/agc.cpp    | 89 ++++++++++---------\n src/ipa/raspberrypi/controller/rpi/agc.hpp    | 32 +++----\n src/ipa/raspberrypi/controller/rpi/lux.cpp    | 17 ++--\n src/ipa/raspberrypi/controller/rpi/lux.hpp    |  2 +-\n src/ipa/raspberrypi/raspberrypi.cpp           | 72 ++++++++-------\n 12 files changed, 181 insertions(+), 121 deletions(-)\n create mode 100644 src/ipa/raspberrypi/controller/duration.hpp"
