Dear Petr,
I missed the point that the second Community thread is from the space for the Freescale FAEs only, but there is no Linux driver in it either, just some additional settings, which, I thought, might be useful for your application (or not...).
The point with a Linux VADC driver is that the only development platform of ours (but not necessarily of our "board partners") with analog video inputs is the above-mentioned Vybrid Automotive board, whose code is not Linux-based; thus, I am afraid we do not have it - maybe timesyssupport...
BTW, in general, our policy for Vybrid is that boards based on it do not have Linux support (unlike for other processors).
Sincerely, Naoum Gitnik.
