Enable HDMI features on NanoPC-T6

[PATCH 0/2] Enable HDMI features on NanoPC-T6

Posted by Marcin Juszkiewicz 10 months, 2 weeks ago

This patchset follows other SBCs and enables second HDMI output and then
enables HDMI audio on both ports.

Tested with 1920x1080@60 and 3440x1440@60 displays. Worked nice, audio
played on both monitors.

Would be nice to have an option for more than 60Hz (larger screen can do
75Hz) but I assume that this will come one day.

3440x1440 can be used up to 90Hz with 600 MHz TMDS signalling [0].
So it does not require FRL and as far as I know should work once
the scrambling support patches from Cristian (added to Cc) land.
