| |
| 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. |
