Zoom OMAP34x-II Mobile Development Platform uses a Silicon Image
SiI9022 HDMI encoder without HDCP.
SiI9022 (TFBGA84 6x6 mm 0,5mm pitch package) is included in baseboard
shematics found at http://omapworld.com/zoom.html
Google Sil9022.c and Sil9022.h for drivers.
NDA is required for SiI9022. However, it should be possible to
implement in your design without, if you can get your hands on samples
or a reel (490 pcs)...
