Subject: [PATCH v7 2/6] dt-bindings: gnss: add w2sg0004 bindings documentation

Add bindings documentation for Wi2Wi W2SG0004 GPS module.

This is a quite old module which does not support a WAKEUP
line and hence can't use a generic SirfStar driver.

+Wi2Wi W2SG0004 GPS module connected through UART
+
+Should be a subnode of the SoC UART it is connected to.
+
+Required properties:
+- compatible:	must be
+	"wi2wi,w2sg0004"
+- 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 */
+        };
+};
