+NXP SC18IS602/SCIS603
+
+Required properties:
+ - compatible : Should be one of
+ "nxp,sc18is602"
+ "nxp,sc18is602b"
+ "nxp,sc18is603"
+ - reg: I2C bus address
+
+Optional properties:
+ - clock-frequency : external oscillator clock frequency. If not
+ specified, the SC18IS602 default frequency (7372000) will be used.
+
+The clock-frequency property is relevant and needed only if the chip has an
+external oscillator (SC18IS603).
+
+Example:
+
+ sc18is603@28 {
+ compatible = "nxp,sc18is603";
+ reg = <0x28>;
+ clock-frequency = <14744000>;
+ }
