I didn't know that HDMI serializers send the logical levels of those lines, I thought some frame/field/line start/end codes are sent instead. I will have to have a closer look at this chip, then. > Do you have a datasheet for this device? No, there is only the current driver and also the old one (in Gateworks' Freescale/NXP kernel). Tim may have something perhaps under NDA, maaybe. I will see if I can find these bits in the registers.
