Apply these patches [1][2][3][4] in addition to this series, and you
should see the SDTV output when running modetest (this is what I used
to test/debug the driver).

This is the command I use to test the SDTV output in NTSC mode

modetest -s 39:720x480

I did most of my test on a RPi-2, but IIRC, Eric tested it on a RPi
(don't know which model).
