+	  Say yes here to provide access to several register-oriented
+	  SMBus I/O expanders, made mostly by NXP or TI.  Compatible
+	  models include:
+
+	  4 bits:	pca9536, pca9537
+
+	  8 bits:	max7310, pca9534, pca9538, pca9554, pca9557
+
+	  16 bits:	pca9535, pca9539, pca9555
 
 	  This driver can also be built as a module.  If so, the module
 	  will be called pca953x.
