gnss: add USB support2021-12-22T14:36:39+00:00Johan Hovoldjohan@kernel.org2021-12-20T11:19:00+00:00urn:sha1:ee4736e50ba261944ddae75469b3eb47a9e2847d
Add a generic driver for GNSS receivers with a USB interface with two
bulk endpoints.
The driver currently assumes that the device protocol is NMEA (only) but
this can be generalised later as needed.
