+description: |
+ 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.
+ maxItems: 1
+
+ timepulse-gpios:
+ description: When a timepulse is provided to the GNSS device using a
+ GPIO line, this is used.
+ maxItems: 1
+
+ current-speed:
+ description: The baudrate in bits per second of the device as it comes
+ online, current active speed.
