Lukas Lao Beyer 5ecfa255d2 Add support for FreeSRP
This patch adds support for both receiving and transmitting using
the FreeSRP. More information on the FreeSRP can be found at:

http://freesrp.org

The gr-osmosdr blocks added make use of libfreesrp, the library
required for interfacing with this device. The libfreesrp source
code is freely available at

https://github.com/freesrp/libfreesrp

Usage example:

osmocom_fft -a "freesrp"

Dimitri Stolnikov 2b79811350 bladerf: implement options for clock configuration
Since firmware 2016.01-rc1 bladeRF has the ability to lock to an
external reference as well as produce arbitrary frequency signal
(25 MHz here) on its clock output.

Use gr-osmosdr source with the following arguments to produce 25
MHz on the SMB connector:

osmocom_fft -a bladerf,smb=25e6

smb=25e6

To lock the bladeRF itself to an external GPSDO reference, use
additional arguments tamer=external for 10MHz or tamer=external_1pps for
1PPS GPSDO signals.

osmocom_fft -a bladerf,smb=25e6,tamer=external

tamer={internal,external_1pps,external}

The described method requires https://github.com/Nuand/bladeRF/releases/
tag/2016.01-rc1

Carefully *read the instructions for external reference locking*
(especially max allowed voltage levels) on Nuand's blog https://
www.nuand.com/blog/2016-01-rc1-release/

Dimitri Stolnikov 5943919828 hackrf: introduce bias=0|1 and bias_tx=0|1 parameters
... to support antenna/phantom power via a new device argument "bias"
(to match Airspy's existing bias power syntax). 0=disable and 1=enable.
I also added a device argument to control bias power at transmit time. I
named this option differently - "bias_tx" - to avoid accidentally
enabling bias power in transmit mode when an LNA may be attached in an
input amplifier configuration.

Dimitri Stolnikov 154c4ddd5f airspy: add support for AirSpy wideband receiver
Requires https://github.com/airspy/host

Usage example:

osmocom_fft -a airspy

The following named gain stages are available:

LNA: 0 to 15, step 1
MIX: 0 to 15, step 1
IF: 0 to 15, step 1

At the moment the gains are not in dB but gain indices internal to R820t
tuner.

Dimitri Stolnikov 9c6ac9e3e3 rfspace: add support for RFSPACE SDR-IQ and SDR-IP
Usage example:

osmocom_fft -a sdr-iq=/dev/ttyUSB0
osmocom_fft -a sdr-ip=host[:port]
osmocom_fft -a netsdr=host[:port][,nchan=2]

The following named gain stages are available:

SDR-IQ: ATT: -20 to +10 dB, in 10dB steps
SDR-IP: ATT: -30 to 0 dB, in 10dB steps

The ftdi_sio driver is being used for SDR-IQ. It creates a character
device of the form:

crw-rw---- 1 root dialout 188, 0 Dec 19 22:14 /dev/ttyUSB0

To be able to open the device without root permissions add yourself to
the "dialout" group or do a "chmod 666 /dev/ttyUSB0" after pluggin in.

Dimitri Stolnikov e5f7b28093 bladerf: add support for nuand LLC bladeRF (WIP)
This is based on the original work (https://github.com/Nuand/gr-osmosdr)
done by folks at nuand LLC for the gr3.6 branch of gr-osmosdr.

The following modifications have been done in this commit:

* port to gr-osmosdr master codebase (gr3.7)
* moved shared properties to bladerf_common
* added & verified IF filter bandwidth setters
* set LMS6002D registers with values taken from FAQ 5.27
* print device information (serial/versions) on startup
* added fpga= and fw= device arguments to program MCU/FPGA
* added bladerf=# dev. arg. to select a specific bladeRF
* grc gain field controls RF path VGA for RX/TX
* grc BB gain field controls BB path VGA for RX/TX

Usage example:

osmocom_fft -a "bladerf,fpga=/tmp/hostedx115.rbf"

The following RX named gain stages are available:

LNA: 0 to 6 dB, in 3dB steps
VGA1: 5 to 30 dB, in 1dB steps; nonlinear mapping done inside the lib
VGA2: 0 to 60 dB, in 3dB steps; not recommended to be used above 30dB

The following TX named gain stages are available:

VGA1: -35 to -4 dB, in 1dB steps, BB side
VGA2: 0 to 25 dB, in 1dB steps, RF side

Thanks a lot to the team of nuand LLC for this major contribution.

Dimitri Stolnikov 3ce7c33981 fcd: add support for FUNcube Dongle Pro+
The gnuradio block https://github.com/dl1ksv/gr-fcdproplus must be
installed before building gr-osmosdr.

Available named gains:

Dongle Classic:

LNA: -5 to 30 dB, in 2.5 dB steps
MIX: 4 or 12 dB

Dongle Pro+:

LNA: 0 or 1, meaning off/on only. no information about real values.
MIX: 0 or 1, meaning off/on only. no information about real values.
BB: 0 to 59 dB, in 1 dB steps

This patch also introduces optional "device" and "type" arguments which
allow to override the values automatically picked by gr-osmosdr:

osmocom_fft -a "fcd,device=hw:2,type=2"

The "device" argument overrides the audio device used by the underlying
driver to access the dongle's IQ sample stream.

The "type" argument selects the dongle type, 1 for Classic, 2 for Pro+.

Thanks to Alexey Bazhin for the initial patch and Volker Schroer for
testing.

Dimitri Stolnikov 3ea0b38810 introduce device discovery api
This API allows to acquire a list of devices connected to the host and
creates an argument string ready to be passed to a source object for
cunstruction.

Each device_t entry contains a "label" entry, which holds the generic
device name which may be shown to the user for device selection.

For certain radio hardware extended entries ("name", "serial", "type")
may be available to make bijective device addressing possible.

The argument string for target types "rtl_tcp" and "file" might be
constructed using the osmosdr::device_t class facilities.

Example:

 #include <osmosdr_device.h>
 #include <osmosdr_source_c.h>

osmosdr::devices_t devs = osmosdr::device::find();

BOOST_FOREACH(osmosdr::device_t &dev, devs) // try to create each dev
  osmosdr_source_c_sptr src = osmosdr_make_source_c(dev.to_string());
