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>; }
