+	  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.
+
+	  This driver can also be built as a module. If so, the module
+	  will be called sch-gpio.
