There are\n3 patches:\n\n1. Add the V4L2_CID_NOTIFY_GAINS control.\n\n2. Fix integer array controls.\n\n3. Update the Pi PH to send WB gains to the sensor when it exposes\nthis control.\n\nThanks!\n\nDavid\n\nDavid Plowman (3):\n include: linux: Add V4L2_CID_NOTIFY_GAINS control\n libcamera: v4l2_device: Add support for integer array controls\n ipa: raspberrypi: Update sensor's V4L2_CID_NOTIFY_GAINS control when\n present\n\n include/libcamera/ipa/raspberrypi.mojom | 1 +\n include/linux/v4l2-controls.h | 1 +\n src/ipa/raspberrypi/raspberrypi.cpp | 22 +++++++++++++++++++\n .../pipeline/raspberrypi/raspberrypi.cpp | 10 +++++++++\n src/libcamera/v4l2_device.cpp | 12 ++++++++++\n 5 files changed, 46 insertions(+)" }
