Subject: [PATCH] gpsd: Add patch to enable + configure PPS in TSIP (trimble)
 driver

In the sysmoBTS 2050, we want to configure the 1PPS output of the
trimble to be active only if it has at least 1 satellite in view,
and want to make the receiver output its time information in UTC,
rather than GPS time.
