Maxim's max12xx series is very similar to the max10xx series, with the
difference of the measurements depth which is upgraded from 10 to 12
bits per channel. Everything else looks the same.

+	  Say yes here to build support for Maxim SPI {10,12}-bit ADC models:
+	  max1027, max1029, max1031, max1227, max1229 and max1231.
 
 	  To compile this driver as a module, choose M here: the module will be
 	  called max1027.
