By default, after porting the adv7180 driver to android r10.3 on mx53, you will get the "rolling screen".
we solve the "rolling screen" issue with teammate's effort .
However, we get the "combing and feature artefacts" issue.
so, I porting the unit_test mxc_v4l2_tvin to android platform and run by android console,
I found the mxc_v4l2_tvin test program can run normally, there is no "combing and feature artefacts" issue!!!
so I compare the ioctl calling between the mxc_v4l2_tvin and android r10.3 camera hal + overlay hal,
then I add the ioctl which isn't appear in the android hal but not appear in the mxc_v4l2_tvin to the android hal.
However, there is no any improvement.
I can't find the key point about this issue.
anyone can get me some suggestion?
