+* Plantower PMS7003 particulate matter sensor
+
+Required properties:
+- compatible: must be "plantower,pms7003"
+- vcc-supply: phandle to the regulator that provides power to the sensor
+
+Optional properties:
+- plantower,set-gpios: phandle to the GPIO connected to the SET line
+- reset-gpios: phandle to the GPIO connected to the RESET line
+
+Refer to serial/slave-device.txt for generic serial attached device bindings.

+&uart0 {
+	air-pollution-sensor {
+		compatible = "plantower,pms7003";
+		vcc-supply = <&reg_vcc5v0>;
