+ 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.

+ SPI driver for Microchip MCP23S08 I/O expander. This provides
+ a GPIO interface supporting inputs and outputs.
