u-blox GNSS Receiver DT binding
|
|
The u-blox GNSS receivers can use UART, DDC (I2C), SPI and USB interfaces.
|
|
Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
|
properties.
|
|
Required properties:
|
|
- compatible : Must be one of
|
|
"u-blox,neo-8"
|
"u-blox,neo-m8"
|
|
- vcc-supply : Main voltage regulator
|
|
Required properties (DDC):
|
- reg : DDC (I2C) slave address
|
|
Required properties (SPI):
|
- reg : SPI chip select address
|
|
Required properties (USB):
|
- reg : Number of the USB hub port or the USB host-controller port
|
to which this device is attached
|
|
Optional properties:
|
|
- timepulse-gpios : Time pulse GPIO
|
- u-blox,extint-gpios : GPIO connected to the "external interrupt" input pin
|
- v-bckp-supply : Backup voltage regulator
|
|
Example:
|
|
serial@1234 {
|
compatible = "ns16550a";
|
|
gnss {
|
compatible = "u-blox,neo-8";
|
|
v-bckp-supply = <&gnss_v_bckp_reg>;
|
vcc-supply = <&gnss_vcc_reg>;
|
};
|
};
