All the A31/A31s devices I own have some kind of HDMI connector wired
to the dedicated HDMI pins on the SoC:
- A31 Hummingbird (standard HDMI connector, display already enabled)
- Sinlinx SinA31s (standard HDMI connector)
- MSI Primo81 tablet (micro HDMI connector)
Enable the display pipeline (if needed) and HDMI output for them.
