+Wi2Wi GPS module connected through UART
+
+Should be a subnode of the SoC UART it is connected to (serdev).
+
+Required properties:
+- compatible: should be one of (depending on precise model)
+ "wi2wi,w2sg0004"
+ "wi2wi,w2sg0084"
+- enable-gpio: the GPIO that controls the module's power toggle
+ input. A positive impulse of sufficent length toggles the
+ power state.
+
+Optional properties:
+- lna-supply: an (optional) LNA regulator that is enabled together with the GPS receiver
+
+Example:
+
+&uart2 {
+ w2sg0004: gps {
+ compatible = "wi2wi,w2sg0004";
+ lna-supply = <&vsim>; /* LNA regulator */
+ enable-gpios = <&gpio5 17 GPIO_ACTIVE_HIGH>; /* GPIO_145: trigger for turning on/off w2sg0004 */
+ };
+};
