+	  Say yes here to support GPIO interface on Intel Poulsbo SCH

 	  The Intel SCH contains a total of 14 GPIO pins. Ten GPIOs are
 	  powered by the core power rail and are turned off during sleep
 	  modes (S3 and higher). The remaining four GPIOs are powered by
 	  the Intel SCH suspend power supply. These GPIOs remain
 	  active during S3. The suspend powered GPIOs can be used to wake the
 	  system from the Suspend-to-RAM state.
+	  The Intel Tunnel Creek processor has 5 GPIOs powered by the
+	  core power rail and 9 from suspend power supply.
 
 	  This driver can also be built as a module. If so, the module
 	  will be called sch-gpio.
