+         Say yes here to support the MAX7319, MAX7320-7327 series of I2C
+         Port Expanders. Each IO port on these chips has a fixed role of
+         Input (designated by 'I'), Push-Pull Output ('O'), or Open-Drain
+         Input and Output (designed by 'P'). The combinations are listed
+         below:
+
+         8 bits:       max7319 (8I), max7320 (8O), max7321 (8P),
+                       max7322 (4I4O), max7323 (4P4O)
+
+         16 bits:      max7324 (8I8O), max7325 (8P8O),
+                       max7326 (4I12O), max7327 (4P12O)
+
+         Board setup code must specify the model to use, and the start
+         number for these GPIOs.
