+* Atlas Scientific ORP-SM OEM sensor
+
+https://www.atlas-scientific.com/_files/_datasheets/_oem/ORP_oem_datasheet.pdf
+
+Required properties:
+
+  - compatible: must be "atlas,orp-sm"
+  - reg: the I2C address of the sensor
+  - interrupt-parent: should be the phandle for the interrupt controller
+  - interrupts: the sole interrupt generated by the device
+
+  Refer to interrupt-controller/interrupts.txt for generic interrupt client
+  node bindings.
+
+Example:
+
+atlas@66 {
+	compatible = "atlas,orp-sm";
+	reg = <0x66>;
+	interrupt-parent = <&gpio1>;
+	interrupts = <16 2>;
+};
