Subject: [PATCH v4 4/5] DTS: gta04: add serdev node for w2sg00x4
Date: Wed, 15 Nov 2017 22:37:56 +0100	[thread overview]
Message-ID: <02dde546157359316eebe8e90f5f1de7177bbffa.1510781876.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1510781875.git.hns@goldelico.com>
In-Reply-To: <cover.1510781875.git.hns@goldelico.com>

GTA04 has a W2SG0004/84 connected to UART2 of the OMAP3
processor. A GPIO can pulse the on/off toggle switch.

The VSIM regulator is used to power on/off the LNA of an external
active GPS antenna so that a driver can turn the LNA off if GPS is
not needed to save battery energy.
