I also have impression that LVDS is only supported on TCON0, but that's
mostly from this comment in sun4i_lvds.c:
/* The LVDS encoder can only work with the TCON channel 0 */

Yes, I have the hardware (Cubieboard 2) at hand, but I cannot change the
any physical connections on it. FWIW, it is https://openvario.org, the
device we are (painfully) trying to upgrade from old kernel-3.4 with
proprietary mali drivers to contemporary software.
