We have been getting\nmore and more reports of ov5647 seemingly hitting the Unicam timeout condition,\nlikely due to a sensor fault. There is no error handling as such, simply a log\nmessage indicating a timeout occurred, then an application gets stalled.\n\nThis series improves the timeout handling by putting the pipeline handler in\nan error state, and cancelling any outstanding/future requests. The application\ncan then make a decision on what to do (either close down or attempt a restart)\nwhen these requests come back as cancelled when it was not expecting this.\n\nThanks,\nNaush\n\nNaushir Patuck (2):\n pipeline: raspberrypi: Add an error state\n pipeline: raspberrypi: Improve Unicam timeout handling\n\n .../pipeline/raspberrypi/raspberrypi.cpp | 29 ++++++++++++++-----\n 1 file changed, 21 insertions(+), 8 deletions(-)"}
