This document defines device tree properties common to Global Navigation

Satellite System receivers.

pattern: "^gnss(@.*)?$"

lna-supply:
|
|
description: A separate regulator supplying power for the Low Noise
|
|
Amplifier (LNA). This is an amplifier connected between the GNSS
|
|
device and the receiver antenna.

enable-gpios:
|
|
description: A GPIO line that will enable the GNSS receiver when
|
|
asserted. If this line is active low, the GPIO phandle should
|
|
consequently be tagged with the GPIO_ACTIVE_LOW flag so the operating
|
|
system can rely on asserting the line to enable the GNSS device.
