From 10f146639fee5ffaf7cf0081c1af518f7d0c533c Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 1 Jun 2018 10:22:59 +0200 Subject: gnss: add receiver type support Add a "type" device attribute and a "GNSS_TYPE" uevent variable which can be used to determine the type of a GNSS receiver. The currently identified types reflect the protocol(s) supported by a receiver: "NMEA" NMEA 0183 "SiRF" SiRF Binary "UBX" UBX Note that both SiRF and UBX type receivers typically support a subset of NMEA 0183 with vendor extensions (e.g. to allow switching to the vendor protocol).
