Subject: [PATCH v2 4/5] DTS: gta04: add serdev node for w2sg00x4
Date: Sun, 12 Nov 2017 21:59:57 +0100 [thread overview]
Message-ID: <55121e359ace8568711411de7da68205fc039d56.1510520397.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1510520397.git.hns@goldelico.com>
In-Reply-To: <cover.1510520397.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.
