FYI, we cooked Linux driver which add compatibility layer on top of the HiSilicon DVB drivers.
It allows running on Poplar board the open-source Enigma2 software so the board acts as satellite or terestrial set-top-box.
Small demo shows very nice responsibility of the system:
PS: Out final intention is to have fully open-source drivers, but it is long run journey because HiSilicon drivers are not upstreamed nor open-sourced (yet).
