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

   21   lna-supply:
   22     description: A separate regulator supplying power for the Low Noise
   23       Amplifier (LNA). This is an amplifier connected between the GNSS
   24       device and the receiver antenna.
   25 
   26   enable-gpios:
   27     description: A GPIO line that will enable the GNSS receiver when
   28       asserted. If this line is active low, the GPIO phandle should
   29       consequently be tagged with the GPIO_ACTIVE_LOW flag so the operating
   30       system can rely on asserting the line to enable the GNSS device.

   33   timepulse-gpios:
   34     description: When a timepulse is provided to the GNSS device using a
   35       GPIO line, this is used.
   36     maxItems: 1

   38   current-speed:
   39     description: The baudrate in bits per second of the device as it comes
   40       online, current active speed.
