Nikolaus Schaller" Date: Tue, 31 Jul 2018 09:11:19 +0200 Subject: ARM: dts: omap3-gta04: map antenna detect GPIO to SW_LINEIN_INSERT key event GTA04 can detect presence/absence or plug-in of an external GPS antenna through a gpio. The best match for an event code is SW_LINEIN_INSERT. Signed-off-by: H.
