Subject[PATCH v2] arm: dts: gta04: add gps support
Date
The GTA04 has a w2sg0004 or w2sg0084 gps chip. Not detectable
which one is mounted so use the compatibility entry for w2sg0004
for all which will work for both.

Signed-off-by: Andreas Kemnade <andreas@kemnade.info>
---
Changes in v2:
- some s/gps/gnss/
- not added vcc-supply because the regulator is not modelled
in dts at all

w2sg0004 bindings are in next-20190129
