-* Atlas Scientific EC-SM OEM sensor

-http://www.atlas-scientific.com/_files/_datasheets/_oem/EC_oem_datasheet.pdf
-
-Required properties:
-
-  - compatible: must be "atlas,ec-sm"
-  - reg: the I2C address of the sensor
-  - interrupts: the sole interrupt generated by the device
-
-  Refer to interrupt-controller/interrupts.txt for generic interrupt client
-  node bindings.

-Example:
-
-atlas@64 {
-	compatible = "atlas,ec-sm";
-	reg = <0x64>;
-	interrupt-parent = <&gpio1>;
-	interrupts = <16 2>;
