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).

are there any advices to test this feature?

Is it possible to use an old Raspberry Pi B (256 MB RAM) for this?

Thanks

I'm happy with the series and I'm just waiting for the DT ack.

[RESEND PATCH v2 0/7] drm/vc4: VEC (SDTV) output support

Sorry for the noise, but I forgot to Cc the DT maintainers.

Here is the 2nd version of the VC4/VEC series.

We still miss the two clock patches mentioned by Eric in the first
version to make the encoder work no matter the setting applied by the
bootloader.

Regards,

Boris
