The support for interlaced video modes seems to be broken; we don't use anything other than the vtotal/htotal from the timing information to define the various sync counters.
Freescale patches for interlaced video support contain an alternative sync counter setup, which we include here. This setup produces the hsync and vsync via the normal counter 2 and 3, but moves the display enable signal from counter 5 to counter 6. Therefore, we need to change the display controller setup as well.
The corresponding Freescale patches for this change are: iMX6-HDMI-support-interlaced-display-mode.patch IPU-fine-tuning-the-interlace-display-timing-for-CEA.patch
This produces a working interlace format output from the IPU.
