A\nfairly simple change is made identically to all of them.\n\nThanks!\nDavid\n\nDavid Plowman (2):\n ipa: rpi: Add an HDR algorithm to drive multi-channel AGC\n ipa: rpi: vc4: data: Update tuning files for HDR\n\n src/ipa/rpi/common/ipa_base.cpp | 49 +++\n src/ipa/rpi/controller/hdr_algorithm.h | 23 ++\n src/ipa/rpi/controller/hdr_status.h | 25 ++\n src/ipa/rpi/controller/meson.build | 1 +\n src/ipa/rpi/controller/rpi/hdr.cpp | 129 +++++++\n src/ipa/rpi/controller/rpi/hdr.h | 42 +++\n src/ipa/rpi/vc4/data/imx219.json | 388 +++++++++++++++-----\n src/ipa/rpi/vc4/data/imx219_noir.json | 388 +++++++++++++++-----\n src/ipa/rpi/vc4/data/imx477.json | 386 +++++++++++++++-----\n src/ipa/rpi/vc4/data/imx477_noir.json | 388 +++++++++++++++-----\n src/ipa/rpi/vc4/data/imx708.json | 350 +++++++++++++-----\n src/ipa/rpi/vc4/data/imx708_noir.json | 350 +++++++++++++-----\n src/ipa/rpi/vc4/data/imx708_wide.json | 350 +++++++++++++-----\n src/ipa/rpi/vc4/data/imx708_wide_noir.json | 350 +++++++++++++-----\n src/ipa/rpi/vc4/data/ov5647.json | 392 ++++++++++++++++-----\n 15 files changed, 2832 insertions(+), 779 deletions(-)\n create mode 100644 src/ipa/rpi/controller/hdr_algorithm.h\n create mode 100644 src/ipa/rpi/controller/hdr_status.h\n create mode 100644 src/ipa/rpi/controller/rpi/hdr.cpp\n create mode 100644 src/ipa/rpi/controller/rpi/hdr.h" }
