This document defines device tree properties common to Global Navigation
|
||
|
|
Satellite System receivers.

$nodename:

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.

timepulse-gpios:
|

description: When a timepulse is provided to the GNSS device using a
|
||
|
|
GPIO line, this is used.

online, current active speed.
