Help offering for AmLogic S905Y2 Mainline Effort

Hi,

recently bought a cheap HDMI Stick Computer with an AmLogic Chip (x96s) 
because i was told that it had mainline linux support. That seems to be 
true only partly because there are drm drivers missing for the gpu and 
no video encoding/decoding support.
Because i would like to get these things working in the future i would 
like to offer my help.
I already ripped that thing open to get acces to UART to see boot progress.
Could someone please guide me where i can help with the mainlining effort?

Thanks
