We have the driver in FreeBSD for almost two years now, whne I started to see how to upstream it I noticed a lot of problems and spent 4 or 5 days to try on all the SoCs mentionned in the serie, the only SoC I didn't include it the A83T as for some reason I couldn't make the driver work. I just hope that you understand that we cannot wait for Linux to have a driver to have some bindings.
