Hi all:

   Now we use embeded sync(EAV/SAV) to do line and frame sync.

   But we find that some times the data signal be disturbed, then the protection bits(bit0-3) of EAV/SAV are not correct. so we want to disabe the protection bits checking.

   I have try to call _ipu_csi_ccir_err_detection_disable in  ipu_csi_init_interface(the original code is enable protection bits check by call _ipu_csi_ccir_err_detection_enable),

   But it looks like not work, because I also can not capture any TVin video data.

   So my question are:

1. how to disable the detection of EAV/SAV protection bits?

2. and if the protection bits is a wrong value, then whether we can capture the TVin video data?

   Thank you very much!
