It might be somewhere in the Android SDK on this download server (it seems that only SDK has source files - everything else is either documentation or binaries). Either way, I'm very surprised that people from linux-sunxi git repo are ignoring this, as official git repo for sunxi still has the old driver (which is pretty much unusable).
Also ov5640 driver is much better in the qubir link that I've sent you - not sure if it can be used for our stuff, as it seems that V4L2 integration is a bit different. The same goes for CSI unfortunately, so I'll probably have to use heavily modified kernel from git. By the way - on the download server that you've sent there is a nice document about A10's CSI unit - I'm just preparing to read it. Of course, if I find anything, I'll post back.
