+         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.
