Re: gr-osmosdr: add clock_source= parameter

[Michael Loeffler]

Hello,

over three years ago I submitted this patch and it probably wasn't 
noticed so I send it again. The patch still applies without conflict to 
the current version of gr-osmosdr.

Hello,

the attached patch allows to set the clock_source on uhd devices in
programs like gqrx.

Bye

Subject: [PATCH] uhd: add clock_source= parameter

Allow to set the clock_source on uhd devices in programs like gqrx.
Typical values for clock_source= are "internal", "external" or "gpsdo"
depending on the hardware.
