+ *  PXA2xx pin mux configuration support
+ *
+ *  The GPIOs on PXA2xx can be configured as one of many alternate
+ *  functions, this is by concept samilar to the MFP configuration
+ *  on PXA3xx,  what's more important, the low power pin state and
+ *  wakeup detection are also supported by the same framework.
