I couldn't find the original tree. However, the original driver look awkward on my eyes. So, I decided to write a new version from it from the scratch, while trying to reproduce everything found there. TODO: - After locking, the original driver seems to have some routines to improve reception. This was not implemented here yet. - RF Gain set/get is not implemented.
