<br>
<br>Well, my plan was to get at least minimum bits mainlined and then build
<br>additional features on top.
<br>
<br>Wens, it would be cool though, if you could share your plans.
<br>
<br>Unfortunately I have only single A10 device (with LVDS and mini-HDMI)
<br>but I don't actually have other LVDS-displays I could easily use with
<br>A20 devices (I have CubieTruck and A20-Olinuxino Micro).

<br>Päikest,
