This driver enables the "takeover" of a serdev bus device by the GNSS
subsystem. It can be used to test the GNSS subsystem without needing to
write a specific hardware backend.
The new module supports the following parameters:
gnss_cmdline.serdev=driver/port/serdev
gnss_cmdline.type=<protocol number>
An example which allows GNSS to wrap a platform serial8250 port and
advertise NMEA-0183 data is:
gnss_cmdline.serdev=serial8250/serial0/serial0-0
^ ^ ^
driver port serdev
gnss_cmdline.type=0
^
GNSS_TYPE_NMEA
