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-6m" |
|
"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>; |
|
}; |
|
};
