2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotRequired properties:
4*c66ec88fSEmmanuel Vadot	- compatible : Should be one of
5*c66ec88fSEmmanuel Vadot		"nxp,sc18is602"
6*c66ec88fSEmmanuel Vadot		"nxp,sc18is602b"
7*c66ec88fSEmmanuel Vadot		"nxp,sc18is603"
8*c66ec88fSEmmanuel Vadot	- reg: I2C bus address
9*c66ec88fSEmmanuel Vadot
10*c66ec88fSEmmanuel VadotOptional properties:
11*c66ec88fSEmmanuel Vadot	- clock-frequency : external oscillator clock frequency. If not
12*c66ec88fSEmmanuel Vadot	  specified, the SC18IS602 default frequency (7372000) will be used.
13*c66ec88fSEmmanuel Vadot
14*c66ec88fSEmmanuel VadotThe clock-frequency property is relevant and needed only if the chip has an
15*c66ec88fSEmmanuel Vadotexternal oscillator (SC18IS603).
