From 1f4f84e955342ebba3295f100693073a412c8f46 Mon Sep 17 00:00:00 2001 From: Andreas Kemnade Date: Thu, 31 Jan 2019 19:06:40 +0100 Subject: [PATCH] ARM: dts: gta04: add gps support 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.
