imx8QXP bt656

[brian_kim]

I trying bt656 camera sensor with imx8qxp.

We have no error. but It's not fill isi buffer or pixel link buffer. (Our camera sensor already checked.)

This is log.

I think parallel-csi driver code of imx8qxp is not work for bt656. is right ?

As the blow link,

https://community.nxp.com/t5/i-MX-Processors/imx8qxp-support-bt656/m-p/825322#M126902

NXP tech support said,

"you need to change some source code, which depends on what camera and what mode you use"

Is it included "parallel-csi" driver code or just sensor driver code ?

Hi Brian

one can refer to TVIN patches below

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/ISL79987-and-adv7180-de-interlace-driver...
