[media] r820t: Add a tuner driver for Rafael Micro R820T silicon tuner
This driver was written from scratch, based on an existing driver that it is part of rtl-sdr git tree, released under GPLv2: https://groups.google.com/forum/#!topic/ultra-cheap-sdr/Y3rBEOFtHug https://github.com/n1gp/gr-baz http://cgit.osmocom.org/rtl-sdr/plain/src/tuner_r820t.c (there are also other variants of it out there) >From what I understood from the threads, the original driver was converted to userspace from a Realtek tree. 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.
