Camera video frame shift problem on IMX8MM CSI + NEXTCHIP N4 (NVP6324, NTSC)

This is a problem that occurred during the NEXTCHIP N4 (NVP6324, CSI) video decoder test on IMX8MM.

It uses mx6s_capture.c and mxc_mipi_csi.c drivers based on Linux 4.14.78-GA1.0.0 version.

There is a problem that the captured video frame shifts like the attached file.

Hi Yulsang

Linux 4.14.78 is old kernel and not more supported, suggest to try

latest for example L4.14.98, may be useful to look at

MIPI Camera Frame corruption in IMX8MM when MIPI_DOUBLE_CMPNT and MIPI_YU_SWAP is enabled in CSI_CSI... 

Best regards

Hi 

Fixed the problem of left rolling by setting FCC bit of CSICR1 register to 0.

Thank you!
