Please, see: https://lists.freebsd.org/pipermail/freebsd-arm/2014-March/007822.html

Gonzo did the LCD driver (which feed data into HDMI framer) and tried
to port the TDA19988 HDMI framer driver.

I've fixed the i2c controller issues on -head so you can skip that
part from gonzo's patch.

I also see some GPIO pins on schematics (like GPIO0_19 and GPIO1_27 on
page 3) which may need to be set for the HDMI support and i did not
check the gonzo's code to verify if they are properly set.
